INFLUENCE OF THE MODES PRODUCTION OF REACTIVE-SINTERED CARBIDE CERAMICS ON THE STRUCTURE AND PROPERTIES
Abstract
The structure phase composition and properties of silicon carbide and boron carbide ceramics obtained by reactive sintering have been investigated. It has been found that they essentially depend on the charge composition and the parameters of carbide skeleton infiltrated with silicon (total and open porosity, pore shape and size) and on the free silicon content. It is shown that the density, bending strength, hardness of silicon carbide and boron carbide ceramics obtained by reactive sintering, increase with high the compacting pressure of carbide skeleton. The boron carbide and boron carbide with 50 % silicon carbide infiltrated with silicon exhibited the highest properties.
