Use of KO type heat-resistant organo-silicon enamels for insulation of thermal-electrode wires

Experimental data are presented on the mechanic and insulation characteristics of organo-silicon enamels for insulation of thermal electrode wires. The behaviour of microthermocouples with the enamel insulation irradiated by the integral dose of thermal neutrons of approximately 1.5x1021 n/sm2 has been observed. The insulation is highly elastic and has good adhesion to wire. The organo-silicon clad microthermocouples can be applied for long-term measurements up to 700 and 850 deg C, and for short-term measurements-up to 800 and 1000 deg C. The insulation is highly efficient when irradiated in a reactor up to the thermal neutron fluences of 1x1021 n/sm2, at temperatures near 450 deg C
