Abstract

Procedure for the production of insulating material with high electrical resistance based on granulated, melted or sintered magnesium oxide, with a degree of purity above 94% by weight, characterized in that with the granulated product, before the subsequent treatment of If known to form the insulating material, 0.1 to 7, preferably 1 to 5% by weight, of silica gel with high specific surface area and with a grain size below 370 μ, preferably below 70 μ, are mixed.
