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)

The use of large crystal fused magnesium: 
Large crystal electric melting magnesium is mainly used in refractory materials, spray filler, electric fusion ramming material, furnace filler, coating material, refractory mud, building materials, etc., is made of pure natural high purity light burned magnesium powder by 3000KVA electric melting and large crystal electric melting sand, is a senior alkaline refractory material. With high purity, good ratio of calcium to silicon, large crystal size, stable physical and chemical properties, mainly used in metallurgy, chemical industry, electrical appliances, aerospace and national defense and other industrial fields.
