Cheap Aluminum Oxide Abrasive Media Wholesale Price

In recent years, due to rising prices and rising electricity prices, the production pressure of brown fused aluminium oxide is increasing, and market competition is so fierce that the quality of white corundum produced by many illegal merchants is getting worse. As a wear-resistant material, white corundum often has unstable quality in recent years, and powdering and bursting often occur.

Therefore, it is very important to judge the quality of white fused alumina price in the process of purchasing white alumina. Some of the impurities in refractory materials are fusible materials, and some have high melting points, but when coexisting with the main component, fusible materials can be produced. During this period, Alcoa (now renamed Almatis) has developed a series of plate-shaped white aluminum oxide abrasive products based on low-Na2O industrial alumina.


Therefore, the white fused alumina presence of impurities often has a strong fluxing effect on the main component. Although the fluxing effect sometimes helps the liquid phase sintering of the material, it has serious harm to the material's resistance to high temperature. There are two methods for making white corundum. The most important is to produce white fused aluminium oxide by electrofusion. The production process is based on high-quality bauxite, no annoying coal, and iron filings.


Purification, impurity removal, crystallization, separation, crushing, magnetic separation, sieving and other black aluminum oxide media processing methods at high temperatures above ℃ make products of various particle sizes. The quality of white corundum will affect its effect. How to judge the quality of white corundum? White corundum contains impurities during the production process. The main impurities are SiO2, Fe2O3, and TiO2. The less impurities, the higher the quality of pink fused alumina.


If it contains impurities, it will affect its fire resistance. Judging the content of impurities in white aluminum oxide has become a method to judge the quality of white corundum. In addition, the amount of Al2O3 in white corundum directly indicates the quality of white corundum. Plate-shaped alumina, also known as plate-shaped alumina, is a kind of sintered alumina. It is quickly sintered at a high temperature of 1925 ° C, which is slightly lower than the fused aluminium oxide melting point of α-Al2O3 (2050 °).


pink aluminium oxide can also be used as a refractory material. Showing a two-dimensional planar plate-like shape with many intercrystalline and intracrystalline cylindrical closed pores. The slab corundum was obtained by sintering in the shaft kiln invented by Thomas S. Curtis in 1934. It was commercialized in 1935 after an intermediate test and used as a lining material for refractory and ceramic industry furnaces. In the 1950s, it was only used in the aluminium oxide grit suppliers refractory industry as a bulk refractory aggregate.
