THERMORESISTIVE MATERIAL Russian patent published in 1995 - IPC

FIELD: electronics. SUBSTANCE: cobalt oxide in the amount of 50-70 per cent by mass is used as metal oxide in material containing zirconium oxide 24-45, yttrium oxide 5-10 per cent by mass. Use of certain quantity of CO₃O₄ in composition of thermoresistive material enhances specific conductivity by several orders leaving absolute dielectric permittivity of thermoresistive material without change. As a result of active and reactive resistances of thermoresistive material grows. EFFECT: enhanced specific electric resistance and thermoresistive factor of resistance at temperature 200 C. 1 tbl
