Sintered Magnesia Brick MgO 85%
Sintered Magnesia Brick MgO 85% for cement rotary kiln burning zones. High alkali resistance and thermal stability; ideal for lime kilns, industrial glass furnaces, and non-ferrous smelting furnaces.
// Key Features
- High refractoriness under load for rotary kiln burning zone stability
- Excellent alkali and CO gas corrosion resistance
- Good thermal shock resistance under rotary kiln cycling conditions
- Low apparent porosity reducing slag and alkali infiltration
