                                    Magnesia Refractory  Brick

What is the magnesia refractory brick?

It is made by burned magnesia or electric fused magnesia, its MgO content is above 91%.

it has High pressure forming, and high-temperature 1600-1700°C sintered.

Features

1. High refractory,usually the refractoriness is above 2000°C.

2. Refractoriness under load about 1500-1550°C because of poor high-temperature intensity.

3.Strong ability to resist basic (alkaline) slag,can not contact with acid refractory material.

4.Poor Thermal shock resistance,so keep the temperature of furnace stabilized.

5.Poor Volume stability at high temperature,must set aside appropriate expansion joint when laying brick.

6.Strong ability of thermal conductivity,sometime need insulating material.

7. Hydrability, keep product away from moisture during storage.
