Calcium Silicide CaSi2 Pulver:
Calcium silicide (also known as calcium diilicide) is an inorganic chemical, which acts as a silicide for calcium. CaSi2 is the molecular form of calcium silicide. Its molecular mass is 96.2514g/mol. A solid, off-white, dark gray, or black substance with melting points of 1033°C. Hot water can decompose it. Calcium silicide may spontaneously ignite in air and is highly flammable. Calcium silicide may be made by reacting Si and Ca in an inert environment at 850°C.
Characteristics Of Calcium Silicide CaSi2 Pulp:
CaSi2 CaSi2 (CAS 12013-56-78) is a calcium silicide with a high melting temperature, high corrosion resistance and high resistance to oxidation.

How isSilicide CaSi2 Chloridemanufactured?
1. By melting elemental calcium and silicon, you can obtain calcium silicide of higher purity. However, the process must be completed in two steps.
Mix the silica powder and calcium shavings together in a bowl. After that, you need to quickly place the porcelain vessel into the quartz reaction tube and add CO2. Once the temperature of the porcelain boat is at 1000°C, the mixture will melt quickly. You can remove the porcelain vessel and immediately boil the CaSi. CaSi, a porous stone with metallic luster and lead-gray coloring, is made.
Next, mix CaSi powder with the calculated amount Si powder. Finally, heat the mixture at 1000°C under an H2 gas stream. The final step of the reaction is slow and requires that it be heated for 15 hour.
2. To prepare CaSi2, mix pure silicon and pure CaO, with the appropriate fluxes CaF2 or CaCl2 at 1400°C. Then melt with a lot of silicon.
Calcium Silicide Powder
Calcium silicide has many applications. Here are some examples:
Calcium silicides are used in the manufacture of special metal alloys.
It’s used to create special combinations in the pyrotechnics sector, including smoke, flashing elements, striking caps, and flashing components.
For certain initiators and pyrotechnics, calcium silicicide can be used.
Silicon and calcium alloys are mostly used in the foundry and steel industries as desulfurizers or deoxidizers.
The corrosive nature of calcium silicide can be found in all metals.
Calcium intermetallic silicide (CaSi2) can be formed by simultaneously decreasing the calcium oxide content of the electrolyte as well as the silica particle and the dissolved CO2.
In some cases, silicon-based fuel can be used to slow down explosive bolts or grenades. The majority of the components used to smoke are made up of hexachloroethane. They will also produce silicon tetrachloride during combustion. It is similar to the titanium tetrachloride that’s used in smoke screens. Gum arabic is sometimes used in some combinations to prevent the breakdown of calcium silicide.
The ratio of iron oxide to calcium silicide was similar to thermite in self-heating canned military meals. The mixture can be ignited to produce the right amount of heat and not release any gas.
