Product category

ZA-33D products are developed based on the production technology of ZA-33 and improve the glassy phase quality by reducing glass phase content. They also increase their creeping resistance property and decrease of glass phase exudation.

ZA-33D products are suitable for the superstructure of high-quality furnaces and the melter crown etc.
