Category: Molecular sieves

Molecular sieve is a synthetic hydrated aluminosilicate (zeolite) or natural zeolite with the function of screening molecules.Zeolite molecular sieve has a complex and changeable structure and a unique pore system, and is a catalyst with excellent performance.

Uses of Molecular Sieves

Molecular sieve is mainly caused by molecular attraction, which produces a “surface force” on the fixed surface. When the fluid flows through, some molecules in the fluid will make irregular movements and collide with the surface of the adsorbent. Molecular concentration occurs on the surface, and in the overall collision motion, the number of molecules is reduced, so as to achieve the effect of separation.

Calcium Nitride Ca3N2 Powder CAS 12013-82-0

About Calcium Nitride Ca3N2 powder
In most cases, calcium nitride is usually available in large volumes. Tungstenmolybdenummetals provides a wide range of products for hydrogen storage research, advanced fuel cells, and battery applications. Hydrogen is easily produced from renewable energy sources and is the most abundant element in the universe. Hydrogen comes from many sources, such as solid fuels, water, and renewable materials. Hydrogen is non-polluting and will form harmless water during use. Challenges related to the use of hydrogen as an energy source include the development of safe, compact, reliable, and cost-effective hydrogen storage and transmission technology. Currently, hydrogen can be stored in three forms: compressed hydrogen, liquid hydrogen, and chemical storage. High purity, submicron and Nanopowder forms can be considered. Calcium nitride is the main raw material for high-end phosphors. This phosphor is more stable, has better performance, and has better effects at high temperature and high humidity. Last but not least, calcium nitride can also be used as a chemical treatment agent, which is the key to determining the performance of water-based mud. Feel free to send an inquiry to get the latest price if you would like to buy Calcium nitride in bulk.

How is Calcium Nitride Produced?
When calcium burns in the air, it forms Ca3N2 with the oxide CaO. The distilled fibrous metallic calcium is heated to 450°C in a purified nitrogen stream, and then the metallic calcium is nitrided into calcium nitride after 3-4 hours.
Depending on the preparation temperature, the obtained calcium nitride is black at 350°C, milky white at 350 to 1150°C, or golden yellow at 1150°C or higher. It is easy to identify the calcium nitride formed because it can react with moisture or water and produce calcium hydroxide and ammonia.

Applications of Calcium Nitride
Ca3N2 can be used for obtaining reactive nitride ions, Calcium hydride (a desiccant) can be produced by heating calcium nitride with hydrogen at temperatures above 350 °C.

Product Performance of Calcium Nitride Ca3N2 powder:
Calcium Nitride Ca3N2 powder possesses the characteristics of high purity and uniform particle size distribution.
Calcium nitride hydrolyzes to give calcium hydroxide and release ammonia, it dissolves in dilute acids and decomposes in alcohol.

Technical Parameter of Calcium Nitride Ca3N2 powder:

Product Name	MF	Purity	Particle Size	Melting Point	Density	Color

Molecular Sieve Activated Powder

About Molecular Sieve Activated Powder:

Molecular sieve activated powder is the original powder of molecular sieve after roasting activated at high temperature to remove the water in the channel, with excellent dispersion and strong adsorption activity.

Trace water is an important issue in the production and preparation of Polyurethane (PU) products. Trace water in polyols reacts with isocyanate to form carbon dioxide, resulting in foaming. At the same time, a large amount of heat is released, resulting in a shorter service life (operation time). JLH series molecular sieve activated powder added to polyurethane and other products system, can be effective selective adsorption of trace water in typical polyurethane formula, inhibit the occurrence of side reactions, so as to reduce the bubble generation and extend the purpose of application period. Jlh-03-b and JLU-PU are especially suitable for polyurethane system.

RHCO+H2O–RNH2+CO2

In addition, in some special paint or coating system, raw materials, solvents, pigments and additives, etc.) in trace moisture can cause adverse effects, such as in zinc metal or coating, the existence of trace moisture will react with lively metallic pigment of zinc, aluminum and other generate hydrogen gas, will cause the tank pressure is too high, even in extreme circumstances cause leakage. JLH series molecular sieve activated powder can effectively adsorb trace water in the system, inhibit the formation of hydrogen.

JLH series molecular sieve activated powder has excellent chemical stability, molecular sieve activated powder itself will not react with the use of the system.

Applications of TRDN-2 Special Molecular Sieve Adsorbent For N2O:
TRDN-2 molecular sieve is loaded on the molecular sieve bed of the air purifier, with a thickness of about 100mm. It can carry out deep removal of N2O gas after preliminary treatment, and the removal rate is ≥98%.
In normal use, after TRDN-2 molecular sieve reaches to the adsorption saturation, it can desorb and regenerate at high temperature by variable temperature adsorption.

Molecular Sieve Waste Treatment & Disposal:
Molecular sieve can be treated and disposed of as general solid waste after use.
