Before you search the Zirconia Brick in the Internet, you may have so many questions such as: What is an introduction for the zircon brick? Where is zircon brick mainly used? What is the specific chemical and physical index for Zircon bricks? RS can help you solve these problems.

High Quality RS Group Zirconia Bricks for Sale


Zirconia bricks / Zircon brick 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. 

What is the main applications of zircon brick? 

 Zirconia bricks are mainly used in the glass industry. They are installed as lining for working ends and feeder channels in melting tanks. Consequently, zircon refractories are only installed in the lower bottom courses of the melting tank with lower temperatures if soda - lime glass is being produced.

Why is Zircon Brick mainly used in the glass industry?

Zircon bricks has a very high melting point of 2700˚C. Zirkon bricks is a highly refractory material with good resistance to corrosion. In addition, zircon refractories have an important function as seperation layer between silica and fusion cast materials in order to prevent contact reactions.

In the glass industry bricks out of zircon and corundum are installed occasionally. Such bricks have higher corrosion resistance against glass than pure zircon and are also installed in glass contact areas or in the superstructure of glass melting tanks.

The Zircon - corundum materials are also advantageous for hot repair work due to their more favorable thermal shock resistance in comparison to the fusion cast meterials usually installed.

Refractory mixes on a corundum –zirkon base are ofter installed in bottoms of glass melting tanks as a monolothic bottom layer fort he upper paving course out of fusion cast bottom plates.

Typical Application for Zirconia Bricks:
  • Ladle lining for metallurgical industry
  • Glass contact portion of alkali free or low-alkali glass melting furnace
  • Soda-lime glass kiln as neutral brick, skew brick
  • Paving and sub paving, channel blocks, sidewall of meter of glass fiber furnace and floating glass tanks
  • Upper area of flame space or frequent thermal shock region, lining of alkali-free or low-alkali glass, sodium-calcium glass, boron-silicate glass, ceramic glass, lead glass, and other technical glass melting furnace
  • Special region of glass tank, such as paving part and secondary layer of paving bottom, back lining, wall and bottom of fore hearth, flowing spout and spinning portion, melter, etc.
  • 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, areas of crown, burner, thermal couple, peep hole, and secondary layer of melter bottom and its back lining, etc
RS Group Refractories handle many types of Zirconia/Zircon 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. Please contact RS for detailed information and datasheet of the best quality at the most competitive prices worldwide.

Corundum high-strength wear-resistant refractory castable is a wear-resistant refractory castable formed by high-strength and low-cement combination materials cemented with corundum, silicon carbide and other substances. Corundum is a trigonal crystal mineral with a melting point as high as 2050°C and a thermal expansion coefficient of 8.6*10-6K-1. It is a material with moderate to low thermal shock resistance. The hardness of corundum is 9, which is only lower than diamond and a few synthetic high-hardness minerals. Corundum products have high strength. For example, the compressive strength of alumina ceramics can reach 2000MPa, the flexural strength can reach more than 250MPa, and the hot flexural strength at 1000°C is 150MPa. Therefore, the corundum in the corundum high-strength wear-resistant refractory castable has strong resistance to wear. Corundum high-strength wear-resistant refractory castable Corundum high-strength and wear-resistant refractory castables are mainly used at ...

The Technical Development of EAF Steelmaking   has a history of about 100 years. Although always facing the challenges and competition of several other steelmaking methods, especially the impact of high-efficiency oxygen converter steelmaking, the proportion of steel production in electric arc furnace steel production in the world's total steel output continues to rise year by year. Electric arc furnace steelmaking relies on graphite electrodes to generate electric arc, which converts electric energy into thermal energy in the arc light. Steelmaking method of melting furnace charge and removing impurity components such as sulfur and phosphorus, and then adding required elements (such as carbon, nickel, manganese, etc.) to smelt various steels or alloys with different properties. Furnace temperature can be accurately controlled with electric energy heating, which produces less high-temperature exhaust gas, and the thermal efficiency of electric arc steelmaking fur...

Graphite electrodes are mainly divided into ordinary power graphite electrodes, high power graphite electrodes, impregnated graphite electrodes, high bulk graphite electrodes, and ultra high power graphite electrodes. Due to its thermal and electrical properties, it is widely used in various industries. The main uses of graphite electrodes are as follows.   Uses of Graphite Electrodes First, for electric arc steelmaking furnace Graphite electrodes are mainly used in electric furnace steelmaking. Electric furnace steelmaking uses graphite electrodes to introduce current into the furnace. A strong current generates an arc discharge through the gas at the lower end of the electrode, and uses the heat generated by the arc to perform smelting. According to the capacity of the electric furnace, graphite electrodes with different diameters are used. In order to make the electrodes continuously used, the electrodes are connected by electrode screw joints. Graphite electrod...
