Composition of Silica Bricks

What is silica bricks? Silica brick is a good refractory consisting of several key components, including silica dioxide (SiO2), alumina oxide (Al2O3), and iron oxide (Fe2O3). The price of silica bricks varies with the content of these components.

Silica (SiO2)

Silica (SiO2) is the main component of silica bricks, with a content of over 94%. It has a high melting point and low thermal conductivity, which gives the silica bricks excellent resistance to high temperatures and thermal stability.

Alumina (Al2O3)

The alumina content in silica bricks from 0.5% to 2.5%, alumina is often added to silica bricks as a stabilizer and strength enhancer. It improves the mechanical strength and resistance to deformation of the bricks at high temperatures.

Iron Oxide (Fe2O3)

Iron oxide (Fe2O3) is another component found in silica bricks in the range of 0.3%-2.5%. Although the Fe2O3 content is generally kept low, it can influence the firing behavior and overall characteristics of silica bricks.

Acid Resistant

Silica bricks have excellent resistance to acidic environments. The high silica content makes them highly resistant to acid corrosion, including sulfuric, hydrochloric and phosphoric acids.

Load Softening Temperature

Silica bricks are high-load softening temperature refractory bricks. It refers to the temperature at which the brick begins to deform under a specific load. Silica bricks can withstand high temperatures without significant deformation or loss of strength.

Thermal Stability

Silica bricks have excellent thermal stability. Their high melting point and low coefficient of thermal expansion allow them to retain their shape and integrity under extreme thermal conditions.

Volume Stability

Silica bricks have good volumetric stability, which means they shrink or expand minimally when exposed to heat or temperature changes. This property ensures that the brick retains its shape and dimensional stability.

Thermal conductivity

Silica bricks thermal conductivity is low, which helps to minimize heat loss and maintain uniform temperatures within furnaces. It also helps to improve energy efficiency and reduce fuel consumption during high-temperature processes.

Silica Bricks Uses in Various High-temp Furnace

Different furnaces have different requirements for the performance of silica bricks, which results in various prices for different kilns. The following are the uses of lime silica bricks in different furnaces. If you don’t know whether the equipment is suitable for silica bricks, you can also Contact Us at any time.

Coke Oven

Coke ovens are used to produce coke. Silica bricks are used in the walls, roofs and combustion chambers of coke ovens because of their high temperature resistance and excellent acid resistance. These bricks can withstand the high temperatures and chemical conditions in coke ovens.

Hot Blast Furnace

The hot blast furnace is an essential component of steel production. Silica bricks are suitable for lining hot blast furnaces because of their high refractoriness and ability to withstand heat and chemical environments. The bricks help maintain the structural integrity of the furnace and provide insulation to prevent heat loss.

Glass Kiln

Glass kilns are used to produce various glass products. Silica bricks are suitable for the walls and arches of glass kilns because of their excellent thermal stability and resistance to chemical attack. Meanwhile, these bricks help maintain the high temperatures required for the glass melting and forming process. Silica bricks also provide insulation and reduce heat loss from the kiln.


Silica bricks are used in incinerator linings for waste treatment. They are able to withstand high temperatures and resist chemical reactions with combustion gases and ashes. Silica bricks help control and direct the heat generated during the incineration process, which ensures efficient waste combustion and reducing the risk of structural damage to the incinerator.

Using Case of Silica Bricks

Automated Production Process of Silica Brick

The refractory bricks manufacturing process plays an important role in determining their price, which includes selecting raw material, mixing, forming, drying, firing, cooling and checking, packaging and shipping. The complexity of the silica bricks manufacturing process, production efficiency and the production equipment directly affect the overall production cost. Ultimately these will influence the price of silica bricks on the market.
