Silicides Ceramics Perts

Silicides Ceramics Perts


Silicides ceramics or aluminosilicate ceramics are a class of materials that include compounds based on silicon and other alloying additives. The class of materials has gained its popularity and popularity due to the relatively low cost and universal properties that satisfy many basic applications.

The main materials are:


  • Magnesium Steatite Silicate Mg3(Si4O10)(OH)2, with impurities of iron, aluminum, manganese, etc.

  • Cordierite is an alumosilicate of magnesium and iron (Mg,Fe)[Al3Si5O18]*nH2O

  • Mullite - aluminosilicate 3Al2O3*2SiO2, 2Al2O3*SiO2
