Effect of ageing time on pressure slip casting of silicon

Binary silicon carbide powder mixtures with the particle size distribution designed to optimize the particle packing density were dispersed in aqueous medium in the absence and in the presence of different amounts of a deflocculant The influence of ageing time on the rheological behaviour of finer powder slurries and on relative green density and rate of wall buildup was studied for
