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, using a tilting furnace with a diameter of 6.5m in order to pursue the high-grade and stable quality.
4. Various specifications can be supported.

Applications
