Dense zircon/zirconia refractory bricks are made by isostatic pressing production technology, characterized by good homogenous and dense structure, good resistance to high temperature, thermal shock, and glass liquid erosion, mainly used in non-alkali glass and borosilicate glass: the bottom blocks, superstructure blocks tuckstones, transition bricks, flow blocks, and thermalcouple blocks, and peephole blocks etc.
