Abstract

PURPOSE: To obtain SiCl4 at a reaction temp. far below a conventional temp. in a high yield by reacting a mixture of an Si-contg. substance and C with Cl2 after adding a B-contg. compound to the mixture.
CONSTITUTION: Powder of an Si-contg. substance such as silica having ≤100μm particle size is mixed with powder of C such as activated carbon having the same particle size, and to the mixture is added a B compound such as B2O3 so that B is contained by 0.03W2g atoms to 1g atom of Si. The resulting mixture is dehydrated by heating at 150W1,000°C in an inert gaseous atmosphere or under evacuated pressure. The dehydrated mixture is then reacted with Cl2 at 400W1,200, especially 450W1,000°C to obtain SiCl4. This reaction is smooth and gives gaseous SiCl4. The product SiCl4 can be recovered easily by condensation, distillation or other known method.
