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.
