INVESTIGATION OF THE THERMOSTABILITY OF GLASS-CERAMICS OF A LITHIUM ALUMOSILICATE COMPOSITION
E. I. Suzdal'tsev UDC 666.03.01 This paper presents the results of investigations of the thermostability of the glass-ceramics obtained by ceramic technology with the use of the method of casting blanks from high-density aqueous suspensions of lithium alumosilicate glass with their subsequent sintering and crystallization under combined conditions of treatment. It is shown that the basic factors influencing the thermostability of materials are the values of the elastic modulus, CTLE, and porosity. Experiments and calculations indicate that the glass-ceramics exceeds the known radiotechnical-purpose pyroceramics in thermostability and can be used in articles designed to operate under hard conditions.
