Refractory - China

The following are the products about Refractory from China supplier and manufacturer TAOANG. Refractory materials must be chemically and physically stable at high temperatures. They must be resistant to thermal shock, chemically inert, and have specific thermal conductivity ranges and the coefficient of thermal expansion. Refractory materials are helpful for the following functions: Serving as a thermal barrier between a hot medium and the wall of a containing vessel; Withstanding physical stresses and preventing erosion of vessel walls due to the hot medium; Protecting against corrosion. They are providing thermal insulation. Refractories have multiple valuable applications. In the metallurgy industry, refractories are used for lining furnaces, kilns, reactors, and other vessels which hold and transport hot mediums such as metal and slag. The refractory materials can be divided into Acidic refractories, Basic refractories, Neutral refractories, Shaped refractories, Unshaped refractories. China TAOANG Fused aluminum oxide is a professional plant of White fused aluminum oxide, brown corundum, dense fused aluminum oxide, and bubble aluminum oxide.

Refractory - (FAQ) - China Manufacturer

What is silicon carbide?

Silicon carbide is a chemical compound of silicon and carbon and belongs to the group of carbides. The chemical formula is SiC.Silicon carbide is at the same time the hardest and lightest ceramic material and is also highly resistant against acids and alkaline solutions.

What is the specific surface?

The specific surface means the outer surface of a substance including all accessible pores in relation to the mass. It is determined using the Brunauer-Emmett-Teller (BET) method.

What is porosity?

Porosity is defined as the gas proportion (cavity volume) of a particle’s total volume. It can be determined using different measurement techniques, such as gas adsorption and mercury porosimetry. With the same grain size and shape, a lower bulk density corresponds to a higher porosity of the grains.

What does the form factor (grain shape) indicate?

The description of the grain shape can range from “angular” to “acicular” to “spherical”. When the value of the dimensionless form factor is 1, the grain is spherical. The smaller the form factor, the pointier the grain.
