High Purity Calcium Silicide CaSi2 Powder CAS 12013-56-8, 99% |

Calcium Silicide CaSi2 powder :
Calcium silicide (also known as calcium disilicide) is an inorganic silicide. The molecular weight of calcium silicide (96.2514g/mol) is CaSi2. Melting point is 1033degC. It can be off-white to dark gray. It is not soluble in water. However, it decomposes in hot water when it meets calcium hydroxide and hydrogen. It decomposes when heated water is added. It is flammable, and can spontaneously ignite in the air. Calcium silicide may be produced by reacting Ca and Si at 850degC in an inert gas atmosphere. It’s a solid that can range from white to dark gray and black, with a melt point between 700degC and 935degC.

What is Calcium Silicide CaSi2 Powder produced?
1. By melting calcium and elemental silicon, a silicium with a higher purity can also be produced. It is necessary to carry out the process in two steps.
The first step is to mix the pure silica powder and calcium shavings evenly. Next, pour the CO2 into a quartz reaction tube and quickly place the hard biscuit porcelain vessel into it. The boat is heated to 1000degC. In just a couple of seconds, the mixture melts. Remove the porcelain vessel, and the CaSi immediately coagulates and is crushed. CaSi, a porous material with a metallic sheen and a gray-lead color, is made of a block.
The second step is to mix CaSi evenly with the Si powder calculated, place it in a Nickel boat and heat it up at 1000degC under an H2 stream. It is necessary to heat it for 15 hours because the final phase of the reaction occurs slowly.
2. CaSi2 can be prepared by mixing pure CaO, silicon and appropriate fluxes CaF2 & CaCl2 at 1400degC. The silicon element is then added.

Calcium Silicide (CaSi2) Powder :
Calcium silicide is used in many ways. There are many uses for calcium silicide.
Calcium silicides are used in the production of special metal alloys. They can be used for phosphorus removal or as deoxidizers.
In the pyrotechnics business, it’s used to create special mixtures like smoke, flashing components and striking caps.
Some pyrotechnics components, such as initiators and pyrotechnics smoke, are made with calcium silicide.
The steel and foundry industries use silicon and calcium alloys primarily as deoxidizers and desulfurizers.
The calcium silicide found in refractory and other metals is highly corrosive.
CaSi2 is produced by reducing both the calcium oxide and silica in the electrolyte, as well as the carbon dioxide dissolved.
In some time-delay blends, silicon-based fuels are used, for example, to control explosive bolts and grenades. They can also be used as infrared decoys. The smoke components are usually hexachloroethane. They will, during combustion, produce silicon-tetrachloride. It is the same as the titanium-tetrachloride that’s used in smokescreens. Some mixtures contain gum arabic, which inhibits the decomposition process of calcium silicide.
During World War II, thermite-like iron oxide and calcium silicide were used in the cans to heat up. When the mixture is ignited it produces a suitable amount of heat, but no gas.
