White fused alumina W3.5 is a high-hardness abrasive for Tantalum metal polishing. Tantalum is a high-refractory metal. It is suitable for making crucibles, jewelry, etc. It has the following benefits when grinding refractory metal jewelry tantalum products
White electrocorundum is one of the most important refractory raw materials. There are several properties of WFA:
White Fused Aluminum Oxide 320# is a good lapping powder for grinding piezoelectric ceramic atomization discs. White fused alumina 320# is a kind of aluminum oxide powder made from a fusing process. It gains high hardness and grinding power.
Glaze is an important component of ceramic tiles. Good glaze can not only improve the practicality of ceramic tiles but also enhance their aesthetics and grade. Adding 99% aluminum oxide powder 6000 # and 8000 # to ceramic tile glaze can improve its wear resistance, scratch resistance, corrosion resistance, and other performance. The cost of aluminum oxide powder is also much lower than that of zirconium silicate powder.
Choosing the wrong blasting media always causes uneven surface or black surfaces when sandblasting acrylic, plastic, and aluminum products. However, white fused alumina F012 and F016 will not blacken or contaminate the objects that need to be treated.
UV coatings, also known as photosensitive coatings or photocurable coatings, typically use ultraviolet radiation as the curing energy source and can quickly solidify into a film without the need for heating. UV-curable coatings can be applied to different substrates such as paper, PVC plastic, wood, leather, and other materials. Fused alumina powder is an important functional additive in UV coatings, in addition to photosensitive resins, film-forming agents, and photoinitiators. White aluminum oxide powder F240, F360, and F800 are commonly used grits.
The insulating powder used for sintering ceramic sheets usually refers to the insulating material spread under the sagger during the sintering process of the sintered ceramic sheets. The use of white electro-corundum 24A F230 for sintering ceramic sheet insulating powder has obvious advantages.
White electro-corundum, also known as white melted aluminum oxide. The grades of white electro corundum 25A 24A 23A are abrasive types in the Russian market according to the aluminum oxide purity and grits.White electro corundum 25A 24A 23A is a high-temperature resistant abrasive in the form of grain and powder. It is mainly composed of aluminum oxide (Al2O3), but in fact, it is artificial corundum, and the performance of artificial abrasives is not inferior to that of natural abrasives. May contain small amounts of other impurities. It is produced by arc melting of industrial aluminum oxide loose powder.
Since the appearance of white fused alumina and quartz are similar, some suppliers of white fused alumina mixed quartz sand in the sand. That is very harmful to the quality and caused to poor grinding performance. To identify white fused alumina (WFA) and quartz sand, users can consider the following characteristics:
Low sodium white aluminum oxide is an advanced form of white corudum. White Fused aluminum oxide with Na2O content of less than 0.2% and less than 0.1% is fused from a mixture of low soda alumina powder and special additives. It reduces the smelting process β The content of alumina has increased α Aluminum oxide conversion rate. β Aluminum oxide is harmful to all aspects of the performance of white alumina without any benefits. It has a negative impact on the microhardness, bending strength, thermodynamic properties, specific gravity, and density of white alumina. The α-phase conversion rate of normal WFA is about 90% with sodium content of 0.3-0.4%. That is not conducive to the better grinding and fire resistance performance of white alumina.
