Synthesis of Boride Composite Powder via Fused and Carbon Thermal Reduction

Abstract:

In order to synthesize the high performance and low cost boride composite powder, in this experiment the cheap raw materials ZrSiO₄ and CaCO₃ combining with H₃BO₃, carbon source (graphite or petroleum coke), and the agent for crystal type conversion are used to synthesize ZrB₂·SiC and CaB₆·B₄C compound via the fused and carbon thermal reduction method in the electric arc furnace (EAF). Different types of the fine composite powder are obtained by grinding the corresponding compound.
