Abstract:
     The heat treatment is characterized in that the kiln is heated from room temperature with a rate of 50-100 deg.C per hr., when the temperature has gone up to 490-550 deg.C, keep the temperature for 1-4 hr., then cool down with a rate of 10-17 deg.C per hr. until room temperature. The zinc oxide resistance sheet treated by present method features good quality, good thermal stability and anti-ageing.
