Critical products (pots, crucibles, mixers) from ceramic materials are used in the manufacturing of optical glass.

 

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.
