magnesia cupel is a better conductor of heat -cs ceramic co.,ltd

For example, the temperature of the cupeling alloy in a dense magnesia cupel does not rise so far above muffle temperature as it does in a bone-ash cupel, because the magnesia cupel is a better conductor of heat. This is the principal reason for good magnesia cupels giving lower losses than bone-ash cupels.
