摘要（英）：

The invention relates to an anode material of a K-type thermocouple capable of stably measuring temperature at high temperature for a long time and a preparation method. The anode material of the K-type thermocouple comprises the compositions of, by weight, 8.0-12.0% of Cr, 0.2-0.8% of Fe, 0.1-0.7% of Al, 0.1-0.5% of Si, 0.1-0.3% of Co, 0.03-0.08% of Y, 0.1-0.4% of Mo, 0.005-0.03% of Zr, 0.005-0.03% of La, less than and equal to 0.015% of C, and the balance Ni. The anode material of the K-type thermocouple has oxidation resistance and carbonization resistance, and can keep the integrity and temperature ability of wire material at high temperature; the using temperature range of the K-type thermocouple is increased, and the anode material of the K-type thermocouple can be used in high temperature environment (the using temperature can reach 1320 DEG C in a short time within 30 hours).
