Abstract
- Abstract: Silicon carbide–aluminium nitride ceramic composites were prepared by gelcasting method. The effect of the solid contents of the slurry on the relative densities, mechanical properties of the green bodies and the pressureless sintered ceramic composites were investigated. When the solid contents increased from 35 to 40vol.%, the mechanical properties, such as elastic modulus, flexural strength and fracture toughness simultaneously increased due to the improving of the relative density. But when the solid contents reached to 42vol.%, the mechanical properties became noticeably worse, which caused by the sharply increase of the slurry viscosity, and many defects such as large scale and uneven pores also can be observed in the green bodies and the sintered ceramic composites.
