Diaspor refractories often possess the undesirable characteristic of continual shrinkage in service, and since it is not practical to alter such properties in the present manufacturing processes, the object of this study was to devise, if possible, a manufacturing process to overcome this shortcoming. This part of the paper reveals the mechanism of the firing shrinkage and describes the effect of particle size, time and temperature upon the shrinkage of diaspor clays of various compositions. The properties of the two major constituents of a typical sample are given, as well as photomicrographs of interesting samples. Part II will describe experimental work conducted to devise shrinkage processes and the properties of products so made.
