Product Description

Electrical Grade Magnesia is used as insulating material for atomic energy producing sector, highly pure magnesium oxide ceramics, automotive brakes, and for manufacturing of refractory bricks. It can be used as a filler material between coil and outer sheath of heating elements. This compound is produced by treating raw magnesite material over temperature of 2800 degrees Celsius. Electrical Grade Magnesia has low amount of boron, iron, and sulphur.



  • Can withstand high temperature of up to 950 degrees Celsius

  • Optimum silicone and lime ratio

  • Has moisture resistance nature





Electrical grade magnesium oxide is fused magnesia that has been manufactured at a temperature in excess of 2800oC.

Due to electrical grade magnesium oxide's great thermal conductivity, good electrical insulation properties at high-temperatures, high melting point: It is an ideal material for electrical equipment.

There are four main types of electrical grade magnesium oxide that are generally produced:

1. Ordinary: Operates between 300-600oC

2. Low-temperature, moisture resistant: Operates between 300-500oC

3. Medium-temperature moisture resistant: operates between 500-800oC

4. High-temperature: Operates at 800-100oC, it typically does not operate above 950o


 If you need something slightly different we should be able to help you. Please remember our company specializes in magnesite (MgO) based products.
The stated minimum order is FCL, however the preferred minimum order is 100 tons, as we may have to set up the product line.
However usually have already these products in stock, then great value can be achieved by ordering by FCL or more, as there is a cost per order and per container.

Please contact us if you have any questions; as many things are negotiable as long as there is mutual benefit.
When you contact us please inform us of the use, chemical index, quantity and packing, delivery time.
As different grades (electrical, animal feed, fertilizer, industrial) have different prices.
