Hollow Glass Sphere Hollow Glass Beads

About Hollow Glass Sphere Hollow Glass Beads:
What is hollow glass microsphere? Hollow glass microspheres, sometimes termed microballoons or glass bubbles, have diameters ranging from 10 to 300 micrometers. Hollow spheres are used as lightweight fillers in composite materials such as syntactic foam and lightweight concrete. The hollow glass bead is a kind of specially processed glass bead, which is mainly characterized by smaller density and poorer thermal conductivity than glass bead. It is a new kind of micron-grade light material developed in the 1950s and 1960s. Its main component is borosilicate, with a general particle size of 10~250μm and a wall thickness of 1~2μm. Hollow glass beads are characterized by high compressive strength, high melting point, high resistivity, small thermal conductivity and thermal shrinkage coefficient, etc., and they are known as the “space-age material” in the 21st century.
Hollow glass microspheres, also known as bubbles, microbubbles, or micro balloons, are usually formulated from borosilicate – sodium salt glass mixtures and offer the advantages of low density, high heat and chemical resistance. The walls of glass microspheres are rigid and are usually about 10% thick of the diameter of the spheres. At present, spherical particles have a wide range of densities, from as low as 0.06g/ C3 to as high as 0.80g/ C3, with particle sizes ranging from 5um to 180um. The compressive strength of the hollow sphere is determined by the wall thickness of the hollow sphere and, as expected, the greater the density of the sphere, the higher the compressive strength.The lightweight hollow glass sphere is chemically stable, non-flammable, non-porous, excellent water resistance. Tungstenmolybdenummetals is a trusted global Hollow Glass Sphere Hollow Glass Beads supplier.

Product Name	Content	Particle Size	True Density	Bulk Density	Color
Hollow Glass Sphere	Borosilicate glass	5- 100um	0.12-0.70 g/cm3	0.10-0.40 g/cm3	White

How are Hollow Glass Sphere Hollow Glass Beads Produced?
How do you make glass microspheres?
1. Glass powder method
The glass powder method uses pre-prepared glass powder containing gases such as SO3 to pass through the flame at the temperature of 1100-1500℃. At this time, SO3 and other gases dissolved in the glass powder overflow from the inside of the glass due to the decrease in solubility and the change in the atmosphere of the kiln. At the same time, the glass powder becomes spherical under high temperature due to the surface tension. The spillage gas is sealed in the spherical particles to form hollow glass beads.
2. Spray granulation method
Spray granulation method is made in advance with special auxiliary reagent (boric acid, urea, ammonium pentaborate) aqueous solution of sodium silicate, and then through the nozzle to the solution injection into the spray dryer, is expected to drop after drying to get a certain particle size of powder particles, the final will be powder particle heating foam-forming hollow glass beads.
3. The droplet method
The liquid drop method adopts the same raw materials as the spray granulation method. The raw materials are 500 copies of sodium silicate (M (SiO2): M (Na2O) =2), and the same amount of 10% ammonium perborate aqueous solution is added. After mixing evenly, the hollow glass beads are sprayed into the spray drying tower.
4. Dry gel method
The alkyl salt was added to dilute hydrochloric acid and decompose with water. After gelation, the gel was dried in two stages at 60℃ and 150℃ and then crushed by a ball mill. After grading, the dried gel powder was obtained, which was foamed in a vertical electric furnace at 1280℃ to prepare hollow glass microspheres.

Molybdenum Silicide MoSi2 Powder CAS 12136-78-6

About Molybdenum Silicide MoSi2 Powder:
MoSi2 is an intermetallic compound, molybdenum silicide is a refractory ceramic, mainly used for heating elements. It has a medium-density, a melting point of 2030 ° C, which is electrically conductive. At high temperatures, it forms a passivation layer of silica to protect it from further oxidation. The thermal stability of MoSi2 and the thermal stability of its high radiation make such materials and high radiation coatings in thermal shields from the atmosphere as they are used next to WSI2. MoSi2 is a material with a four-square crystal structure (α-modified) gray metal; its β-modification is hexagonal and unstable. It is insoluble in most acids but is dissolved in nitric acid and hydrofluoric acid.

Although molybdenum silicide has excellent oxidation and high Young’s modulus at temperatures above 1000 ° C, it is brittle at lower temperatures. Moreover, at 1200 ° C or more, it will lose creep resistance. These properties are limited to their structural materials but can be shifted by using it as a composite with another material.

Molybdenum disilicide (MoSi2) is a promising candidate material for high-temperature structural applications. It is a high melting point (2030 C) material with excellent oxidation resistance and a moderate density (6.24 g/cm3). However, low toughness at low temperatures and high creep rates at elevated temperatures have hindered its commercialization in structural applications. Much effort has been invested in MoSi2 composites as alternatives to pure molybdenum disilicide for oxidizing and aggressive environments.

Molybdenum disilicide-based heating elements have been used extensively in high-temperature furnaces. The low electrical resistance of silicides in combination with high thermal stability, electron-migration resistance, and excellent diffusion-barrier characteristics is important for microelectronic applications. Feel free to send an inquiry to get the latest price if you would like to buy Molybdenum Silicide MoSi2 Powder in bulk.

＞99%	＞60%	balance	0.2%	0.02%	0.19%	0.015%	0.05%

How is Molybdenum Silicide MoSi2 Powder produced?
Molybdenum disilicide and MoSi2-based materials are usually made by sintering. Plasma spraying can be used to produce dense monoliths and composite forms. The material produced by this method may contain a certain proportion of β-MoSi2 due to its rapid cooling.

Applications of Molybdenum Silicide MoSi2 Powder:
Molybdenum disilicide heating elements can be used for temperatures up to 1800 ° C, in electric furnaces used in laboratory and production environment in the production of glass, steel, electronics, ceramics, and in heat treatment of materials. Molybdenum disilicide is used in microelectronics as A Contact Material.

Heating element
MoSi2 is a conductive silicide that has an oxidation property due to a stable silica layer on its surface at a high temperature.
Although the top MoSi2 element can operate at temperatures up to 1800 ° C, the material is very brittle, which may suffer serious creep during use. However, they have process advantages because they can work under high electrical loads without aging, and will not exhibit increased resistivity during use. They have antioxidant properties in air, oxygen and oxygen-rich atmosphere.
Moreover, they can be used with ammonia, nitrogen, hydrogen, a rare gas, and limited vacuum, but due to the failure of the protective oxide layer, the operating temperature and life can be reduced.

MoSi2 elements are ready-made elements and can be made into a bending or straight form of a variety of sizes. These elements are mainly used in production furnaces and laboratory furnaces in ceramics, glass, steel, electronics and heat treatment industries.

High-temperature structure
Amazingness and high-temperature elasticity make MoSi2 a very promising material for high-temperature applications such as gas turbine engines. Many researchers strive to improve high temperature creep resistance and low-temperature ductility. However, there are no commercially available composites with all preferred features.
