Synthesis of Thermosetting Preceramic Copolymer

Abstract

Silicon carbide is a well-known ceramic material with high thermal and chemical stability, high mechanical strength and hardness, and high thermal conductivity. There has been much interest in the use of organosilicon polymers as precursors to silicon carbide based ceramics. Some of the advantages in the preparation of ceramic materials from these precursors include, compositional homogeneity in the final products, high purity ceramic products with uniform microstructure, amorphous to microcrystalline, and the preparation of refractory ceramics at relatively low temperatures.
