With the advantage of its lower cost, the main chemical components of fireclay brick are SiO and Al. And the main raw materials are heat resistant bonding clays and fired clays.
Silica brick is a kind of acid refractory mainly made from tridymite, cristobalite and a small amount of residual quartz as well as glass phase. The raw refractory material is natural silica sand whose SiO2Â content should be more than 96%. The higher SiO2Â content in silica sand, the higher temperature silica bricks resist, its refractoriness under load is as high as 1640 ~ 1670.
Glass kiln silica brick has high temperature and volume stability, no pollution to glass liquid, chemical corrosion resistance, small bulk density, and can reduce the weight of furnace body. It also has the ability of resistance to acidic and alkalic steam attack with high performance of flushing resistance.
It is mainly used to build the doghouse crown, suspended wall of channel, top crown and inlet sealing, and also to be used to build the checker chamber, chute, combustion chamber, coking chamber and furnace arch in glass melting furnaces.
Silica brick has good corrosion resistance to glass liquid. It is the preferred refractory for crown construction of glass melting furnaces, in terms of cost, strength and of defect potential.
Zircon brick is an acid refractory brick with the advantages of good slagging resistance, mechanical strength, high refractoriness under load, excellent thermal shock stability, good creep resistance and good corrosion resistance to glass liquids.
Our zircon brick is made from stable zircon sand, it is widely used in the high erosive zones of glass furnace, non-ferrous metal smelting furnace, pure steel furnace, chemical industry, and metallurgy industry, especially 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.
Features:
1. It has advantages with small bulk density, high cold crushing strength, and high refractoriness under load, small dimension tolerance and good thermal shock resistance.
2. It has the lowest and most stable thermal conductivity in various insulating refractory bricks.
3. It can reduce the total weight of furnace body and the thickness of furnace wall effectively, improve heat efficiency, lower energy consumption, improve work conditions and production efficiency, and considerable economic benefit can be obtained.
Application:
It is not only widely used in insulating layers of various of thermal processing equipments, such as hot blast furnace, coke oven, glass kiln, etc, but also apply to linings in parts of furnace without strong high-temperature molten material erosive.

A brief introduction of silica brick
Silica brick is a kind of acid refractory mainly made from tridymite, cristobalite and a small amount of residual quartz as well as glass phase. The raw material is natural silica sand whose SiO2 content should be more than 96%. The higher SiO2 content in silica sand, the higher temperature silica bricks resist. Silica bricks are used in the roof and superstructure of glass melting tanks as well as for hot repairs.
Our silica brick advantages
--Adopts high quality silica and advanced technology, our silica bricks enjoy the advantages of high purity, long service life, good thermal conductivity, high refractoriness under load, and good creep resistance.
--In addition, it has accurate size tolerance, pure color and luster appearance.
--Because of the good thermal shock resistance of silica brick, it is mainly used in the continuous operating furnace.
--Supporting the use of other high quality refractories, our silica brick can extent the service life of float glass furnace to 8 years and double the service life of bottle glass furnace.
Applications
The silica brick can be widely used in coke oven, hot blast furnace, glass furnace and carbon furnace. In glass industry, it is mainly employed to build the doghouse crown, suspended wall of channel, top crown and inlet sealing. In detail, silica bricks plays the following role in different fields:
--being the partition walls in coke oven carbonization and burning chamber;
--metallurgy industry: used as refractories for steel making open hearth regenerator, slag pocket, soaking pit;
--arch crown and other weight bearing areas in ceramic kilns, hot blast furnace and acid open hearth;
--worked as building checker chamber, chute, combustion chamber, coking chamber and furnace arch in glass melting furnaces.
Specifications
1.Higher SiO2 content of more than 96%, with true density of 2.34g/cm3, thus it has good performance in corrosion of acid slag.
2.Excellent resistance in high temperature. The melting temperature under load is 1620-1670â??. Durable, with no deformation under high temperature.
3.Good thermal shock resistance, High heat conductivity.
4.At 1450, there is 1.5-2.2% overall expansion which makes the joint-cutting dovetailed, thus silica bricks have good air tightness and strong structure.
