Jul 24, 2018 · In recent years, in the high temperature zone of hot blast stoves, more and more silica bricks have been applied instead of high-alumina bricks. Because silica brick always maintains a high strength before reaching the softening point due to its good thermal expansion, high load softening point, fluctuating between 1640℃ and 1680℃, close to the melting point of tridymite and cristobalite
The silica brick is composed mainly of mullite, corundum, SiC and glass. It is formed at the junction of granules as mullite, glass and SiC. Features: 01:the product structure is compact and good wear resistance. 02:high temperature and high temperature performance. 03:lower the temperature of the kiln and good insulation performance. Application:
Industrial Quartz Stone Silica Brick Refractory Fire Bricks For Coke Oven / Glass Kiln. Specifications. Silica brick for coke oven silica brick for glass kiln silica bricks for coke oven silica brick is made of quartz stone material, the content of SiO2 is above 93%,it has good resistance to acid slag and good heat conductivity.
Silica Brick Product Description: The Silica brick is the acid refractory,which consist mainly of tridymite,cristobalite, and a small amount of residual quartzand glass phases.The silica content is 95.6% or more.It has acid corrosion resistance and higher temperature strength.
Alibaba.com offers 758 silica brick for glass furnace products. About 94% of these are refractory, 5% are bricks. A wide variety of silica brick for glass furnace options are available to you, such as brick, block. You can also choose from silicon carbide (sic), alumina block, and castable.
Thermal expansion under load (creep) and content of liquid phase are adversely affected by the Al2O3 content in particular. The requirements for silica bricks, which have increased during recent years for coke ovens, blast furnace stoves, and glass furnace have led to the development of extremely dense bricks low in fluxing agents.

Refractories for Glass Furnaces We supply complete refractories for glass furnaces AZS (Alumina Zirconia Silica) is main structural refractory material for glass furnaces primarily since it is not easily wetted by molten glass and because of its low reaction with them.
Silicon fire brick belongs to silicon refractory materials, silica brick is a kind of quality refractory materials products with over 93% SiO2 content. silicate refractory brick has excellent features of good resistance to acid corrosion, great heat conductivity, high refractoriness under load at over 1620℃. and also silica bricks have fratures of strong acid slag erosion resistance, high refractoriness under load, and volume stability at high temperature. silicon rerfractory brik is
General grade silica bricks are most often used in the iron & steel industry, while the super grade to be used on the glass industry. The silica brick refractories have a main characters of high dense( good for thermal conductivity),high RUL and high tridymite content, lower true density, low expansion, low creep and low residual quartz
Silica Insulation Brick has only a small amount of residual expansion and better thermal stability than dense silica refractory bricks. Silica Insulation Bricks can service in the high temperature between 1500~1550℃ for long term but cannot directly contact with molten materials and corrosive gases.
Thermal expansion from 20 to 950°C and physical data of silica brick from various producing districts in the United States and Europe are presented. The variations in thermal expansion of brick from various parts of kilns are given for plants in the United States.
