Induction melting of reactive MgO in a cold crucible in the Kristall-402 equipment makes it possible to produce a periclase with a mass fraction of MgO>99%. Noncontaminating crushing, sieving, and mixing together powders of a specified grain composition plus heat treatment at 1600°C in air ensures that the highest quality periclase in accordance with GOST 13236-73 is obtained. The combined heat treatment of the periclase and an addition of talc increases the electrical resistivity and the general resistivity to hydration. [ABSTRACT FROM AUTHOR] |
