The influence of the temperature of thermal shock and 
the content of MoSi2 on the specific electrical resistance 
of a silicon-nitride ceramic with sintering additions has been investigated. 
The methods of mathematical experimental design and dispersion and 
regression analyses have been used for processing the results obtained 
for specific electrical resistance. It has been established that the 
greatest influence on the specific resistance is exerted by the content 
of molybdenum disilicide, regardless of the dispersity of the starting 
mixtures of powders.
