White fused Aluminum oxide grain F180 for ceramic tile glaze

White corundum 180mesh wear-resistant sand is an artificial wear-resistant material. It also known as white fused Aluminum oxide grain F180.  The particle size range of WFA F180  is 60 to 90 microns. It has the following advantages as a wear-resistant layer for ceramic tile glaze

What is the material of ceramic coating of WFA?

WFA is a traditional abrasive grit for making abrasive discs. It has high self-sharpening capacity and is sharp enough for cutting steel and iron.

But WFA toughness is a little lower than brown fused alumian. Thus, coating a layer of Rare earth or metallic elements can improve the cutting & grinding performance of WFA.

The price of white fused alumina plummeted in 2025!

After the price increase for nearly half a year in 2024, the price of white fused alumina finally loosened at the beginning of 2025. Just after the Spring Festival in 2025, the white fused alumina price plummeted, with a price reduction of about 15%. The price of WFA grit dropped about 130 USD per metric ton compared with before the Spring Festival. However, even so, the increase in the previous price increase was still not taken into account.

New White fused alumina furnace put into production

Recently, the company upgraded the white fused alumina tilting smelting furnace. After the transformation, the output of a single furnace also reached 14 tons, and the production capacity was greatly improved. At the same time, the furnace adopts a circulating smelting method. It can reduce the loss of heat energy and makes the smelting temperature more stable. The upgrading and transformation of production equipment has a great impact on the production of white fused alumina. The performance of white fused alumina has been improved as well. With more complete smelting,  WFA will get higher volume density than ordinary WFA tilting furnace, lower porosity, and reduced cost.

White aluminum oxide WFA/WA 120# for nano-spraying

Before nano-spraying, it is usually necessary to sandblast the surface to improve the adhesion of its nano-film layer. White aluminum oxide WFA/WA 120#,80# and even finer WFA 500# are suitable for this application.

What is platelet alumina powder used for?

Platelet alumina powder adopts a unique calcination process, so that its alumina crystals appear in the form of  tabular shape after calcining. Then the production process including crushing, moisture, precipitation, drying and other processes to make platelet alumina ultrafine powder. This powder has the advantages of high α-alumina conversion rate, mechanical strength and hardness. Here we mainly discuss the use of flat alumina powder.

WFA powder for ceramic industry

WFA powder (WA fine powder or white fused alumina powder) is not only an excellent grinding and wear-resistant material, but also plays an important role in the field of ceramics. The application scenarios of WFA powder in the ceramic field mainly include

White Fused Alumina F24 F36 F60 for bacteriostatic floor coating

White Fused Alumina has wide application range in the anti-slip industry. It is also an excellent aggregate adding to bacteriostatic floor coating.  That usage is from the chemical stability of white fused alumina. 

White fused alumina Grit F24 F36 F60 are proper size for the addtives, it has appearant advantages:

White aluminum oxide 800# for Semiconductor package blasting

Semiconductor packaging is one of the important semiconductor manufacturing processes for connecting between chips and external circuits. Sandblasting of packaging materials is a necessary step for surface treatment. White aluminum oxide 800# is an ideal abrasive medium for metal Semiconductor package blasting. White fused alumina is an artificial abrasive made by high-temperature electric melting. It has excellent self sharpening, hardness, and grinding force.
