摘要
For use as linings in a vacuum resistance furnace, the yttria on grain boundaries of MgO acts as an intrinsic lubricant, facilitating slipping of particles during sintering. According to x-ray phase, x-ray structural, and microprobe tests, the reduction in volatilization due to yttria cannot be explained by the formation of solid solutions or chemical compounds.
