Abstract
Published data on Indian Refractory materials are meagre and are principally confined to chemical analysis. Physical data have not been readily available so far, as prior to the establishment of the Refractories Research and Testing Laboratory at Jamshedpur, by the Tata Iron & Steel Co. about ten years ago, no fully equipped laboratory for refractories study existed in India. Some of the data collected in this laboratory on Indian refractory materials are presented here. Data on corresponding foreign materials are also included.
