Abstract

PURPOSE:To produce a formed Si3N4 having excellent heat-resistance, oxidation resistance and mechanical strength, by reacting a silane halide with a polyhydric alcohol and ammonia, forming the resultant resinous compound and converting the product into Si3N4 by heating in a nitriding atmosphere. CONSTITUTION:A silane halide of formula I-IV (R is H, alkyl, ethyl or allyl; X is halogen) is made to react with a polyhydric alcohol (e.g. glycerol) in the presence of an ammonia-generating compound such as ammonia gas or ammonium carbamate at room temperature - 90 deg.C to obtain a resinous compound. The compound is formed optionally after mixing or impregnating with a material selected from carbon fiber (reinforced carbon composite material), a graphite material, a metal oxide, Si3N4 and SiC and is converted into Si3N4 by heating in ammonia gas or N2 gas atmosphere at 1,300-1,600 deg.C.
