Ceramics Based on Reactively Sintered Boron Carbide
- 5 Downloads
The influences of various processing parameters on phase and structure formation during reactive sintering of B4C materials in a Si melt are studied. The reaction of B4C particles and C with molten Si during reactive sintering is examined. Dissolution of B4C particles in the Si melt during reactive sintering has a negative effect. Methods for increasing the content of B4C particles in the reactively sintered B4C ceramic are discussed.
