HD-65B is recommended for installation as melter sidewalls, bottom paving or patch tile for LCD glass, ceramic glass, low-alkali borosilicate glass furnaces,etc..
HD-69A/B is recommended for installation in the glass contact areas in alkali-free fiberglass furnaces which request high thermal stress or high glass quality, such as tuckstone in melter tank, flow blocks, and bushing blocks, as well as critical areas in low-alkali borosilicate glass furnace
