Abstract
The rate of vacant space and compression strain on heating were evaluated as parameters of cushioning ability in 14 ceramic liners(A:rock wool type, B:ceramic fiber low temperature type, C:ceramic fiber standard type, D:ceramic fiber low temperature standard type, and E:kaolin type)and 3 asbestos ribbons.Concerning the rate of vacant space on heating, the liners could be classified into 2 groups:one that increased significantly and one that increased slightly between 200-400℃, or one that increased slightly and one that was unchanged over 400℃.Concerning compression strain on heating, the liners could be classified into 2 groups:one that decreased slightly and one that was almost unchanged at 200℃, or one that increased with temperature and one that was almost unchanged over 200℃.The coefficient of correlation between the rate of vacant space and the compression strain on heating was significant.
