REACTION MECHANISM OF SILICON AND CARBON IN ALUMINA CARBON SLIDE GATE PLATE

摘要

In the present work reaction between silicon metal and different type of carbons has been studied. The temperature dependence for the formation of nitrides, oxy-nitrides and carbides has been studied. The effect of particle size of starting materials with respect to formation of nitrides and carbides at different firing temperature has been investigated. A co-relation has been drawn between the formation of nitride and carbide with the thermo-mechanical and pyro-cheimcal properties of Al_2O_3-C. Al_2O_3-C slide plates were manufactured on the basis of mis investigation, which has given superior performance.
