Difference In Pyrometric Cone Equivalent Between Raw And Calcined Clay, Charles Alfred Freeman

Bachelors Theses

"In a recent survey of the refractories field with particular respect to the Pyrometric Cone Equivalent of different clays it was suggested that a difference in the P. C. E. value of clays might be found due to different stages of heat treatment that these clays had previously undergone. At present there is considerable apparent lack of information regarding this problem. It is evidenced largely in the samples of clay sent into commercial testing and research laboratories by manufacturers who are attempting to develop definite properties from a given clay or clay body. There is a large difference in the …
