Zhengzhou Yufa Abrasives Group Co., Ltd. grasps the demand, keeps up with the market, and has the courage to innovate and actively explore on the road of new product research and development. It took more than five years to develop a mature electrofusion process sodium removal technology. Through continuous improvement of raw material/additive mixing, electrofusion, crushing, screening and other processes, we have finally developed micro-sodium white corundum blocks, section sand, particle size sand and milling powder with sodium oxide content between 0.01 and 0.10%.

Micro-sodium white corundum improves the melting point, particle density, bulk density, flexural strength, compressive strength, true density, hardness and other properties of white corundum products, laying a solid foundation for the product to enter the high-end market.
