Development of CaF2 special refractory components

Among the non-oxide refractories, the fluorides of Ca and Mg are of considerable importance in the processing of reactive metals and alloys in nuclear industry. This work deals with the development of specific CaF2 shapes for casting of uranium metal ingots. Studies were carried out in optimizing the slip properties to fabricate dense green components which on sintering at 850 °C attain a theoretical density of approximately 85%. An important feature of this work is in providing a synergistic approach in waste recycling and, as well, in maintaining the assured high purity of the metal produced.
