Zhengzhou Yufa Group: 30 years of high-end white Fused Alumina abrasive research

Zhengzhou Yufa Group: 30 years of high-end white Fused Alumina abrasive research, innovation does not stop As a necessity for industrial construction, abrasives can promote the process of industrialization to a large extent. At present, two-thirds of the industrial abrasives are still artificial Fused alumina(corundum) and silicon carbide. In the field of abrasives, the sodium content of corundum has always been a headache. As an impurity in white corundum, its content directly affects the performance of white corundum abrasives. The sodium content in the white corundum abrasive is too high, which will generate a certain amount of β-alumina, which will affect the performance of the white corundum. The most obvious effect is that the crystal hardness of white corundum is reduced, the cutting ability is reduced, it is easy to be pulverized and broken, and the thermal stability is low. The Na2O in white corundum mainly appears in the form of Na2O·11Al2O3. For example, the alumina raw material contains more than 0.6% sodium oxide, and the white corundum produced with it will contain more than 10% β-Al2O3. Therefore, white corundum with high sodium content has relatively poor comprehensive properties, which limits its application in the field of refractory materials and...
