Generally, white fused alumina with grits F60/F80/F120/F220 works as the sandblasting medium for gel coat mold. The higher the mesh number, the smaller the particles of white fused alumina. Accordingly, it will get a finer matte effect.
Aluminium oxide sandblasting powder is suitable for the restoration of dental ceramic dentures. Especially for bonding zirconia substrate and decorating zirconia ceramic materials.
White fused Al2O3 powder for paint always works as a filler material for paints. It can improve wear resistance, corrosion resistance performance. In the formulation of coating paint, there are necessary fillers besides the main resin material. The adding fillers can adjust coating performance such as durability, flatness, etc.
In the smelting of white fused alumina, industrial alumina powder is used as raw material. There always are some impurities in the crystallization process of white corundum during the smelting process. These impurities mainly include SiO2 (silicon dioxide), Na2O (sodium oxide), CaO (calcium oxide), Fe2O3 (iron oxide), and so on. They will directly affect the white-fused alumina quality.
During the second week of December, the aluminum oxide price drops at the pace of last week. In the past month, the price of industrial Al2O3 powder dropped about24% from 660USD to 505 USD per ton. From the end of the market, demand for white fused alumina is still weak. So there is not much support for the white fused alumina price trend.
Generally speaking, white tabular alumina is a refractory material superior to white fused alumina. However, in some specific applications, adding White fused alumina 325 mesh can increase the quality of refractory castables.
This week, the price of raw aluminum oxide powder is about 4.2% percent lower than last week. The average white fused alumina price decreased as well. But manufacturers have less willing to get full capacity. In the meantime, white-fused alumina grit factories don’t stock many materials in case the price gets down more.
From Nov.22th, the raw alumina price drops a lot. So white corundum price is lower accordingly. In the meantime, there is a low demand for white corundum on the user end. Some of the white corundum manufacturers in China begin to offer lower prices to promote sales.
This week, the price of raw Al2O3 powder is getting down more and affecting WFA price. The cost of fused alumina blocks drops. As a result, the price of WFA section sand is lower than last week. On the other hand, many WFA plants in China have less intention to purchase WFA blocks.
Last week, The raw material alumina price decrease slightly. So the function to support the price of WFA is weakening.
