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.

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

Why use zircon bricks for the construction of glass kiln?

In the glass melting furnace, the molten glass liquid and the flame flying material will cause certain erosion and damage to the   zircon refractory bricks   refractory lining of the kiln, which in turn affects the service life of the glass melting furnace. In addition, it is necessary to reduce the pollution of the molten glass. From the performance indexes of representative  zircon bricks  for glass kiln at home and abroad, zircon bricks are more wear-resistant, more resistant to corrosion, and can reduce the pollution of molten glass. Zircon brick with such properties for glass kiln:  1. High refractoriness and high softening temperature.  2. anti-slag liquid erosion ability, strong acid resistance.  3. High compressive strength.  4. Good thermal shock resistance. The zircon brick is used for the working layer of the glass kiln wall, and its density is high, and it is strong against the glass liquid as the working layer of the pool wall. Therefore, the choice of  zir
