Zirconia bricks has the advantage of mechanical strength, excellent stability of thermal shocking and resistance to corrosion of glass liquid. It is used in soda-lime glass kiln as neutral brick,skew brick etc.
Zirconia bricks has the advantage of mechanical strength, excellent stability of thermal shocking and resistance to corrosion of glass liquid. It is used in soda-lime glass kiln as neutral brick,skew brick etc.It is suitable for paving and sub paving, channel blocks as well as sidewall of meter of glass fiber furnace and floating glass tanks
NR-65 mainly used in upper area of flame space or frequent thermal shock region of alkali-free or low-alkali glass, sodium-calcium glass, boron-silicate glass, lead glass and other technical glass melting furnace, such as transition region between up roof silica brick and fusion zirconia-corundum brick or fusion zirconia-mullite brick, transition region between silica brick and magnesia brick, crown, burner, thermal couple, peep hole, secondary layer of melter bottom and its back its back lining, and also used in ladle lining for metallurgical industry.
NRHZ-65 mainly used in glass contact portion of alkali free or low-alkali glass melting furnace, especially some special region of glass tank, such as paving part and secondary layer of paving bottom, wall and bottom of forehearth, flowing spout and spinning portion and melter, back lining of forehearth, and also used in lining of other quality glass furnace and special glass furnace with high corrosion resistance, such as boron silicate glass, ceramic glass, low-alkali or other technical glass.
Zircon brick / Zirconia bricks produced by stable zircon sand have the advantage of mechanical strength, excellent stability to thermal shock, resistance to corrosion, high refractoriness under load and inertness, high density, etc. It is widely used in glass furnace, non-ferrous metal smelting furnace, and pure steel furnace. Please see listed applications on lower right of this page.

We handle many types of Zircon/Zirconia bricks and other Zircon related refractory bricks: High quality Zircon Brick, AZS Brick or bonded AZS brick, Oxidized Fused Cast AZS Brick, and Zirconia-Mullite Brick, etc.
Zirconia bricks can be used with fixed diameter nozzle of billet caster, can also be used for immersion nozzle and long nozzle slag line. Melting zirconia bricks can be used for soda-lime glass melting furnaces the fluid holes and side walls, can also be used in borosilicate and aluminosilicate glass furnace side-walls, curtain walls of glass furnace and fluid.
Zirconium oxide content of zirconium bricks produced by our company is 65%, the bulk density of 3.65 per cent. While also producing zirconia body density is 4.25 tall dense brick. Welcome new and old customers to buy!
