Combined Elemental Synthesis of Boron and Silicon Carbides

Combined Elemental Synthesis of Boron and Silicon Carbides Combined synthesis from powders of elements B, C, and Si at 1400, 1500, and 1650°C is used to prepare heterophase powders in the system SiC–B4C containing 80, 57, and 30 (mol.%) boron carbide. Powders containing only SiC and B4C phases are prepared at 1550°C from a mixture with 5% excess silicon given vibration grinding for 60 h. The powder has a unimodal particle size distribution and d 50 = 3.5 μm with a volume concentration of 12% submicron particles. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Refractories and Industrial Ceramics Springer Journals

Abstract

Combined synthesis from powders of elements B, C, and Si at 1400, 1500, and 1650°C is used to prepare heterophase powders in the system SiC–B4C containing 80, 57, and 30 (mol.%) boron carbide. Powders containing only SiC and B4C phases are prepared at 1550°C from a mixture with 5% excess silicon given vibration grinding for 60 h. The powder has a unimodal particle size distribution and d 50 = 3.5 μm with a volume concentration of 12% submicron particles.
