Calcium Silicide CaSi2 Pulp
:
Calcium silicide (also known as calcium diilicide) is an organic compound and a silicide for calcium. CaSi2 is the molecular formula for calcium silicide. Its molecular mass is 96.2514g/mol. It is a solid, off-white to dark gray or black substance with a melting temperature of 1033degrees Celsius. It's not water-soluble, but it can be broken down by water to produce hydrogen or calcium hydroxide. Hot water can decompose it. Calcium silicide, which is highly flammable, can spontaneously ignite in the atmosphere. Ca metal and Si can react to form calcium silicide at temperatures of 850oC. The calcium silicide is a black or dark grey to white solid having a melting temperature of 700 to 935degC.

Calcium Silicide CaSi2 Powder
produced?
1. By melting elemental calcium and silicon, you can obtain calcium silica with higher purity. However, the process must be completed in two steps.
Mix the calcium shavings with the powdered silicon evenly in a ceramic porcelain boat. After the boat is set, you can pour CO2 into a quartz reaction tube. Once the temperature of the porcelain vessel has reached 1000 degrees Celsius, heat it. Within a matter of seconds the mixture will melt and proceed violently. You can take out the porcelain boat and immediately the CaSi will be coagulated. 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 1000C using an H2 gaz stream. The final step of the reaction is slow and requires that it be heated for 15 hour.
2. To prepare CaSi2, mix pure CaO and silicon together with the appropriate fluxes CaF2 or CaCl2 at 1400 degrees Celsius. Then, add a significant amount of silicon to this mixture.
Calcium Silicide CaSi2 Pulp

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 silicide can be used.
Most commonly, silicon and calcium alloys are used in the foundry and steel industries as desulfurizers or deoxidizers.
The corrosive nature of calcium silicicide 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.
