Pure White Large Crystal Fused Magnesite 97.5%

Fused magnesia is superior to deadburned magnesia in strength, abrasion resistance and chemical stability. Major applications are in refractory and electrical insulating markets. Producers of fused magnesia commonly fall into one of two categories: those producing refractory grades and those producing electrical grades. Few producers serve both markets on a mainstream basis. The addition of fused magnesia grains can greatly enhance the performance and durability of basic refractories such as magcarbon bricks. This is a function of a higher bulk specific gravity and large periclase crystal size, plus realignment of accessory silicates. Refractory grade fused magnesia has exacting specifications and is normally characterised by the following: • Generally high magnesia content (minimum 96 per cent MgO and up to/exceeding 99 per cent MgO) • Low silica; lime:silica ratios of 2:1 • Densities of 3.50 g/cm3 or more • Large periclase crystal sizes (>1000 microns)…
