SEPPE Cenosphere With High Refractoriness

Views: 202     Author: SEPPE     Publish Time: 2023-08-08      Origin:

Cenosphere is a lightweight, inert, hollow sphere filled with inert air or gas, typically produced as a byproduct of coal combustion at thermal power plants.

The main chemical composition of cenosphere is silicon and aluminum oxide, of which silicon dioxide is about 50-65% and aluminum oxide is about 25-35%. Because the solubility point of silicon dioxide is as high as 1725 degrees Celsius, and the solubility point of aluminum oxide is 2050 degrees Celsius, both are high refractory materials. Therefore, cenosphere has a very high refractoriness, generally up to 1600-1700 degrees Celsius, making it an excellent high-performance refractory material.
