Introduction to Graphite Powder

What uses is graphite? It’s used as a demolding lubricant for the production of chemical fertilizer industrial catalysts.
Graphite is a graphite powder that has high-temperature resistance and high lubricity. It can also be used as a high-temperature resistant lubricant and corrosion resistant lubricant.
It can be used to release powder metallurgy, as a metal alloy raw material, or as a lubricant in cable manufacturing.
It’s used for making carbon film resistor, dry mode conductive and preparing conductive coat.
To make fillers and performance enhancers of rubber, plastics, or any other type of composite material to increase wear resistance, pressure resistance, conductivity, or resistance.
Natural graphite can be used to mark pencils, motor brushes, and other professional applications.
An innovative application for nuclear-grade graphite are the ultra-high temperature reactor (UHTR), as well as the next generation nuclear power plants (NGNP).

What is graphite?
Graphite is a form of graphite, but it’s only a powder. This retains all its primary and secondary characteristics.
Graphite, an allotrope for carbon, is called graphite. It is opaque solid and grayish-black. It is oily and can pollute paper.
It has a hardness level of 1-2. With an increase in vertical impurities, the hardness will rise to 3-5. The specific gravity ranges from 1.9 to2.3. The specific surface area of the mineral is limited to 1-20m2/g. Under the condition of oxygen isolation, its melting point is above 3000, so it is one of the most temperature-resistant minerals. It can conduct heat and electricity.
Chemical stability, corrosion resistance. It is not easy to react against acid, alkali, or other agents. Graphite reacts with oxygen to produce carbon dioxide. Strong oxidants, such as potassium permanganate and concentrated nitric Acid, can oxidize graphite.
Natural graphite is not pure, so it often contains impurities, such as SiO2, Al2O3, FO, CaO and P2O5, or CuO. These impurities can often be found in the form quartz, pyrite or carbonate as well as other minerals. Water, asphalt, CO2, H2,CH4,N2 and other gases are also present. The analysis of graphite requires that, in addition to determining the fixed carbon content, volatile matter and Ash must be done simultaneously.

Is graphite dust toxic?
Exercising too much graphite can damage the respiratory system. There have been documented health effects such as pulmonary fibrosis or pneumoconiosis. This is an occupational lung disease. Workers’ lung function and cardiovascular system may also be affected.

What can you substitute for graphite powder in
Although graphite powder can be used as a dry lubricant, it can corrode aluminum when moisture is present. Graphite can be substituted by molybdenum-dioxide MoS2 powder.

What is Molybdenum Carbide Mo2C Powder?

Introduction to Molybdenum Mo2C Powder The molecular formula molybdenum carbide Mo2C is a Molecular Weight of 203.88 with a Carbon Content of 5.89%. It is a dark gray metallic dust that crystallizes into dense hexagonal lattices. The melting point is 2690 and the density is 9.18g/cm3.
This new material is a type of functional material with high melting points and hardness, good mechanical and thermal stability, and good resistance to corrosion. It is widely used in high-temperature resistance, friction resistance, chemical corrosion resistance, and other areas.
With similar electronic structure and catalytic properties to noble metals, it can be widely used as catalysts for reactions involving hydrogens, such as isomerization of alkanes, hydrogenation of unsaturated hydrocarbons, hydrodesulfurization, and denitrification. High hardness, wear resistance and abrasion resistant. It is an important component of molybdenum-molybdenum carbide hard coating and other cermet coatings, and can also be used as wear-resistance and scratch resistance coating.

Structure of Molybdenum Carbide Mo2C
The interstitial structure of metallic carbides is generally accepted. Normal gap alloys have metal atoms arranged in forms like face-centered cubic, hexagonal dense stack (HCP), simple hexagonal and HEX. Nonmetallic atoms enter the Spaces between the metal atoms. The most common gap between metal atoms is the triangular prism or octahedral. The crystal structure and electronic properties of metallic carbides are dependent on their geometrical and electronic elements. Hagg’s empirical rule can be used to describe the geometrical factors. A simple crystal structure is created when the atomic proportion of nonmetal metal is lower that 0.59. While metallic carbides may have simple crystal structures but few compounds have the exact same crystal structure as their parent metals, it is interesting. The molybdenum-molybdenum metal, for example, has a body-centered cubic structure. However, its stable carbides, which have a hexagonal compact piling structure, and carbon dioxides, which have a face center cube structure. The electron factor is another factor that affects the crystal structure in gap alloys. The cooperation between the SP-D orbital and the nonmetallic orbitals of the metal atoms results in bonding.

Rapid Preparation Process of Gadolinium Oxide

What exactly is Gadolinium oxide? Gd2O3 is the chemical formula for gadolinium dioxide. It has a molecularweight of 362.498000 with a melting temperature of 2330 and a density 7.407. It is white in color.

Physical And Chemical Properties of Gadolinium Oxide

Gadolinium oxide is a white, odorless and amorphous powder. It is not soluble, however it can be broken down by acid to create the salt. Exposure to air makes it easy to absorb carbon dioxide from the air and cause it to deteriorate. It reacts with ammonia and can precipitate gadolinium-hydrate.

Preparement Method of Gadolinium Oxide

To make micron-grade gadolinium dioxide powder, mix 10g with hydrochloric acids at 3.23mol*L. Then heat the mixture until it is completely reacted. Finally, add some polyethylene glycol to the solution (which disperses the gadolinium salt). After the colloidal precursor has been stable for quite some time, stir the mix to disperse and dissolve polyethylene glycol. Deionized water was mixed with the prepared colloid. This gave rise to 500 mL suspension. It was then dried by spray drying. For nano-gadolinium, oxide is obtained by calcining the precursor at different temperatures (600-900) over several hours.

Gadolinium Oxide

Development Opportunities 1. It is used in the preparation of gadolinium oxide ceramics. The solubility of gadolinium in stainless steel and nickel-based metals is not known. A second phase, gadolinium-rich eutectic product (Ni Cr, Gd) can easily be formed along the grain boundary. The possibility of anisotropy and second phases from hot rolling makes it possible to create them. Gadolinium oxide can be added to composite materials for a better neutron shielding. The advantages of gadolinium dioxide ceramics include high mechanical strength, excellent wear resistance and corrosion resistance. 2. It is used for the preparation of polyetheretherketone compound with gadoliniumoxid. It is one of the most important special engineering plastics families that has ever been created. The resin has excellent heat resistance, radiation resistance and hydrolysis resistance. The product has been used extensively in many areas, including aerospace, medical, health, electronics and electronic devices.
