Description	Four different s#x0026les of pyrophyllite were tested for their various properties. Possibility of their utilization in making casting pit refractories and other highly thermal shock resistant type of bodies like saggers, combustion tubes etc. was investigated. It was observed that raw pyrophyllite could favourably replace clay grog by 30 to 60% in fireclay refractories with better volume stability on heating even up to 1400°C. As small as 10% of it helped in improving the reheat change and the thermal shock resistant characteristics of fireclay refractories. Tubes produced by slip casting from bodies containing 60 to 70% of pyrophyllite, on firing to about 1475° became almost impervious to air and at the same time showed good thermal shock resistance. These appear to be suitable as combustion tubes and due to their low power factor at high frequency, may be used as insulators in carbon resistors. © 1965, Taylor and Francis Group, LLC
