Phase transformations in a ceramic mold filled with high alloy


After a high alloy is poured into a corundum-sillimanite mold the phase composition in the mold changes and the chemical activity of the mold increases. The post-kilning and post-filling phase composition of disthene-sillimanite is studied. It is proposed that alumina be added to disthene-sillimanite and the mixture be kilned at temperature 1643 K. As a result mullite will form and have a positive effect on the quality of the mold. The new refractory powder can be used to form the lining layer of the ceramic mold.
