DENSE MULLITE CERAMIC SINTERED BY SPS AND ITS BEHAVIOR UNDER THERMAL SHOCK
https://doi.org/10.17073/1683-4518-2018-1-38-42
Abstract
This article reported the influence of raw material, sintering temperature, particle size and Al2O3 content on densification of mullite ceramics. Thermal cycle treatments were conducted to evaluate thermal shock resistance of samples. Microstructures of samples were also investigated to reveal effects of various parametersand thermal test. Flexural strength retention rises while density decreases, resulting from increasing extra space for stress release. Tridymite precipitation is found to be harmful in improving thermal shock resistance.
