The specific features of the diamond treatment of products from silicon nitride based ceramic have been studied. It has been shown that such ceramic is intermediate between oxide and oxide–carbide ceramic by the degree of oxidation, the temperature in the zone of treatment in the process of grinding, and the force indicators of the diamond grinding of ceramic materials. It has been established that, in terms of specific energy intensity, oxide ceramics are characterized by the lowest energy intensity in the process of their treatment. As compared to these ceramics, the energy intensity of the grinding of oxide–carbide ceramic is 2–3 times higher, and nitride ceramic is characterized by the highest specific energy intensity under both deep and elastic grinding conditions, so this fact should be taken into account when determining the conditions for the treatment of products from nitride ceramic.
