Dense zircon blocks have the characteristics of dense crystal structure, high volume density, high temperature resistance, high mechanical strength at room temperature and high temperature, good wear resistance, good thermal shock stability, small reheat shrinkage and high temperature creep, extremely high chemical stability and resistance to alkaline medium corrosion, etc. They are mainly used in glass contact parts with high thermal stress requirements in alkali-free glass fiber kilns - embedded stones in the molten pool, channel blocks, casing blocks and key parts in low-alkali borosilicate glass kilns.
