FIELD: electronic engineering for internal- combustion engines. SUBSTANCE: compound is composed of boron-silicate glass, molybdenum disilicide, silicon carbide, aluminum oxide, and carbon; such composition ensures maintenance of resistor values between 4.0 and 13 kOhm at high voltages and temperatures, noise suppression, and reliable sealing of spark-plug central electrode. EFFECT: improved stability of resistance, noise immunity, and reliability. 2 tbl
