Abstract
PURPOSE: To prepare long Si3N4 whiskers in high yield, by sending a SiO2 gas or a mixed gas of SiO and CO to a carbon reaction pipe impregnated with Mo, etc. using an inert gas, e.g., N2, etc. as a transporting gas, followed by nitrogenating it.
CONSTITUTION: The raw material 1 of a mixture of SiO2 and Si is reduced in the crucible 3 in the gas production furnace 4 kept at ≥1,300°C, to evolve the SiO gas 8. The SiO gas 8 is sent to the carbon reaction pipe 11 heated at ≥1,000°C by the inert gas 6 such as N2, etc. introduced from the gas pipe 7. The reaction pipe 11 is impregnated with a metal such as Mo, etc. The reaction pipe 11 is in a nitrogenating atmosphere by N2 9, etc. introduced from the gas pipe 10, and the Si3N4 whiskers 12 are precipitated and grown on the inner wall of the reaction pipe 11. By using the CO 9, etc. instead of the N2 9 and by reacting the gas under reducing and carbon-impregnating gas atmosphere, the SiC whiskers 12 are obtained.
