A composite, a sintered product of the composite, and a process for producing products from this composite. The composite has a very high volummetric proportion of TiC, and its remainder of a matrix. The TiC constitutes at least 70% by volume and as much as 95% by volume of the ultimate product. The process includes making a green body which can be handled and is thereafter pre-sintered to form a pre-form. The pre-form is oversized relative to the ultimate product. It is sintered and machined, again oversize. Then it is again sintered and subjected to hot isostatic compression, to assume at least a close approximation to the pre-determined dimension of the product. It is characterized by its light weight, resistance to erosion, and resistance to chemical attack.
