Production Method of Copper Silicide Cu5Si Powder

1. Direct Alloying
Mix copper and silicon powders in a 5:1 ratio. Heat the mixture in an electric furnace under an inert gas (argon) at 1000–1200°C. The metals melt and react to form Cu₅Si. Cool the alloy, then grind it into powder.

2. Powder Metallurgy
Press copper and silicon powders into a mold. Heat at 800–900°C for several hours in a vacuum. The powders bond through solid – state diffusion. Break the sintered block into small pieces and mill to get fine Cu₅Si powder.

3. Sol – Gel Process
Dissolve copper nitrate and silicon alkoxide in ethanol. Add water to hydrolyze the silicon compound. Stir to form a gel. Dry the gel at 100–150°C, then heat at 600–800°C to remove organic parts. The remaining solid is Cu₅Si powder.

4. Chemical Vapor Deposition (CVD)
Heat copper chloride and silicon tetrachloride gases with hydrogen at 800–1000°C. The gases react on a heated substrate:
5CuCl + SiCl₄ + 9H₂ → Cu₅Si + 14HCl.
Collect the deposited Cu₅Si powder from the chamber walls.

5. Arc Melting
Melt copper and silicon chunks in an arc furnace under argon. Pour the liquid alloy into a water – cooled mold. Crush the solidified ingot and grind to obtain Cu₅Si powder.
