Effect of charge composition on the structure and electrophysical properties of self-bonded silicon carbide

Computer treatment of experimental data using the method of Kriging permitted an analysis of the structure, phase composition, and electrophysical properties of silicon carbide materials produced by liquid-phase reactive sintering over a broad range of initial charge compositions. The optimal values of the electrophysical properties were determined, and the possibility of predicting the charge composition for the production of material with given electrophysical properties demonstrated.Institute of Materials Science Problems, Ukrainian Academy of Science, Kiev.

Refractory products from semiacid clays from the Barzassk region

Summary The main advantage of ladle semiacid refractories, having the same life as fireclay, is their low cost owing to the use of cheap, local raw materials and small contents of expensive grog.According to approximate calculations, the saving from the use of local semiacid clays and the reduction in grog consumption should be about 6 rubles per ton of goods at the KMC.
