Heat Range of Ceramic Bodies
Heat Range of Ceramic Bodies
(OP)
I need a source to document, from a scientific standpoint but without being too technically complicated, the fact that a vitreous stoneware body fired at cone 5 (approximately 2200 deg F) will remain unchanged when subjected to temperatures of 1000 deg F.





RE: Heat Range of Ceramic Bodies
If you're mixing the clay yourself, or if this is a theoretical question, you may need to provide some more detail:
1) by "unchanged" are you referring to physical properties, microstructure, surface appearance, all of the above?
2) will the body be under some sort of load at 1000F, or in a particular atmosphere, or in contact with some other material?
3) Who is the audience for this document; how scientific should it be; what does it need to prove?
RE: Heat Range of Ceramic Bodies
Your firing temperature is in the porcelain range and if it is porcelain there will be not discernible change at RT. Physical properties do however change while at 1000°F, like the Modulus of Rupture, thermal expansion, and thermal conductivity.
here are two sites with some information on fired vitreous
clays.

Wouldn't an engineering ceramic be more appropriate?
