Abstract
[Problem] To provide a method for producing fine silicon powder which allows for collection of high-purity flaky fine silicon powder from silicon cutting scraps generated during slicing of a silicon ingot, without using a mechanical pulverization means, such as a ball mill, jet mill, or the like. Further, to provide a method for producing fine silicon nitride powder using flaky fine silicon powder as a starting material. [Solution] A silicon ingot 3 fixed to a fixing plate 4 containing aluminum hydroxide is cut using a fixed abrasive grain wire saw 2, and a slurry containing a silicon cutting powder, impurities, and coolant liquid is recovered. The recovered slurry is subjected to solid-liquid separation to extract a cake 18 containing the silicon cutting powder and impurities. The cake 18 is washed for 20-60 minutes through immersion and stirring in an aqueous sulfuric acid solution containing 1-40 wt% of sulfuric acid and heated to 50-90°C.
