Abstract
PURPOSE: To prepare microcrystalline SiC at a low temperature, by reacting a compound having an acetylenic triple bond or a mixture thereof with a compound having a CN group with a silicic acid ions in a neutral or alkaline aqueous solution.
CONSTITUTION: A compound having an acetylenic triple bond, e.g. an organic compound such as C2H2, a metallic acethylide or methylacetylene, or a mixture thereof with a compound having a CN group, e.g. (CN)2, HCN, KCN a cyano complex compound, a thiocyanic acid and a salt thereof, is reacted with silicic acid ions, e.g. SiO2, capable of forming the silicic acid ions in an aqueous solution of an alkali. In the reaction, a nucleation promotor, e.g. SiC, is added thereto or polyvalent transition metallic ions, e.g. Ti, are present to accelerate the crystallization. The reaction proceeds at room temperature W110°C under ordinary pressure, and CO or CO2 gas formed by the reaction is taken out of the reaction system.
