Abstract

Provides an overview of the highly porous ceramic materials currently used for filtration of metal melts and hot gases, filter manufacturers and methods for their production. Gas permeability and high specific surface area in combination with refractory properties allow using of highly porous oxides in processes carried out at high temperatures in chemical media when other materials are not applicable. Ways of improving the operational properties of porous ceramic filters, such as operating temperature, strength, oxidative resistance, bimodal porosity, as well as possibilities of improving the technological process of their production: reduced cost, increased environmental safety of production, reduced time of the technological cycle wereconsidered.
