1. Description
Our Senior silicon carbide refractory stand can offer good heat stability, high mechanical strength at high temperature, excellent thermal stability and distortion resistance at high temperature. Silicon carbide stand can be used in daily ceramics widely, such as sanitary ceramic, daily ceramic, art ceramic, pottery ,porcelain tableware and so on.
A ceramic ware support for use in kilns including a column of oxidic refractory material selected from the group consisting of alumina, aluminum silicate and fireclay, and supporting caps having portions which telescope about the ends of said column and confining said ends against splitting lengthwise thereof, said caps being made of refractory material having a tensile strength of at least 1000 p. s. i. at temperatures up to 2450 degrees F., said caps surrounding the said end laterally.
2. A ceramic ware support according to claim 1, in which the caps are composed of at least 80 percent SiC.
-3. A column of aluminum silicate refractory and supporting caps contacting and completely surrounding the ends thereof, said caps being. made of refractory material having a tensile strength of at least 1000 p. s. i. at temperatures up to 2450 degrees F. 1
4. A ceramic ware support including a hollow tubular column of aluminum silicate refractory and silicon carbide caps recessed to receive and support the ends of said column, said caps telescoping about said ends of said column and confining said ends against splitting lengthwise thereof.
