Special requirements apply to ceramic materials for optical glass making, such as:

  • high purity material suitable for optical melting;
  • high glass resistance and corrosion resistance;
  • lack of interaction of ceramics with glass melt;
  • low wettability by glass melts;
  • resistance to thermal shock (heat resistance);
  • refractoriness;
  • shape stability and strength at maximum operating temperature;
  • low thermal expansion coefficient.

 

Ceramic materials are used in optical glass making for the production of the following products:

  • crucibles, pots for pot-type glass melting furnaces;
  • screw and paddle mixers;
  • elements of lining pot and bath-type furnaces.

 

The main material performance:

  • quartz ceramics (SiO2);
  • aluminum oxide (Al2O3);
  • zirconium dioxide (ZrO2);
  • various ceramic compositions.
