How is chromite powder used as pigment in Ceramics?

On August 20, 2024, we completed the port transportation and loading of 500 tons of chromite sand. 500 tons of AFS45-55 chromite sand is ready to be shipped to customers for foundry use. At the same time, let me introduce the chromite sand we produce for foundry use: Chromite sand is a naturally occurring spinel consisting …

Chromite ore powder is a naturally occurring spinel consisting primarily of the oxides of chrome and iron.
It is a by-product of ferro-chrome production and is mainly used in foundry applications and in glass production.

Walnut sand abrasive is a product made from walnut shells after being crushed, strictly screened, classified and refined through multiple processes.
Its main use is in the sandblasting cleaning industry, such as removing paint, rust, chemicals and other residues on the surface of workpieces to achieve a smooth surface.
Walnut sand abrasive is widely used in various industrial fields due to its special physical and chemical properties, including but not limited to spray cleaning of glass, wood and plastic.

The main differences between green silicon carbide and black silicon carbide are raw materials, production process, physical and chemical properties, and application areas.

The functions and uses of green silicon carbide are very extensive, mainly including abrasives, refractory materials, functional ceramics, metallurgical mineral processing, electrical and chemical industries and other fields. ‌

In today’s chemical industry, the chemical stability of materials is a crucial performance. Especially in the face of complex conditions such as high temperature, high pressure, and corrosive environment, whether the material can maintain its stable properties is directly related to the efficiency of industrial production and the quality of the product. Zirconia, as an important inorganic non-metallic material, has a wide range of applications in many fields due to its unique physical and chemical properties. This article will focus on the chemical stability of zirconium oxide and its importance in the chemical industry.

Brown fused alumina is made from Calcined Bauxite. It is a hard and tough material, used in manufacturing of grinding wheels (both vitrified and resin bonded) and coated products.
These grains are also used for shot blasting and as polishing media.
Refractory grade BFA is used as a raw material in the manufacture of high alumina refractory..

White Fused alumina (WFA）was made from the high quality alumina by melting above 2000 in the electric arc furnace and cooling.
It is white with the main crystal phase α-Al2O3.
The white alumina produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved.

Compared with brown corundum, white corundum has higher purity and greater hardness than brown corundum, and it will not color the surface of the workpiece during polishing and other operations. It has many advantages that brown corundum does not have. Why can’t white corundum replace brown corundum? The editor of Haixu Abrasives will introduce it to you.
