Study on gelcasting and properties of recrystallized silicon carbide
Source abstract
Abstract
Gelcasting of recrystallized silicon carbide (RSiC) was described in this paper. The Zeta potentials of recrystallized silicon carbide powders dispersing in aqueous solution and the rheological property of the suspension were investigated. A concentrated suspension of solid loading as high as 75 vol.% for gelcasting was prepared successfully. At the same time the complex green bodies with uniformity of density and high flexural strength were fabricated by gelcasting through this kind of suspension. The performance and microstructure of green bodies and sintered samples was measured and observed. Recrystallized silicon carbide parts were prepared by gelcasting.
