1. White corundum powder is widely used in steel, cement, ceramics, petroleum and other industries.

2. It is an ideal raw material for making large-scale ladle castables, medium and high-grade iron trough castables, gunning materials, preforms and other unshaped refractory materials.

3. It is also the main raw material for various corundum products such as corundum bricks, corundum and mullite corundum saggers, corundum porous plugs for refining, integral spray guns and composite nozzles, and high-temperature industrial furnace lining materials.

Other spec are available upon request. Low sodium, Micro sodium WFA are both available.

Product Advantages

1. Low sodium and micro sodium WFA can be provided. Na2O can be double 0.

2. Bulk density can really reach 3.6 g/cm3, which can meet needs of various high-grade refractory materials.

3. YUFA spends 24hours non-stopping melting the WFA with a diameter of 6.5m in order to pursue the high-grade and stable quality.

4. Various specifications can be supported.
