Fired refractory bricks can be broadly categorized into five main types based on the composition of the refractory material: carbon-containing refractory bricks, silicon-alumina refractory bricks, zircon-containing refractory bricks, and basic refractory bricks, among others. Let's take a closer look at the main components of these materials!

One of our company's news items is about refractory bricks made of alumina (Al2O3) and silicon dioxide (SiO2), mainly including:

Silica brick, primarily composed of SiO2, is an acidic refractory brick.

2. Clay bricks, high-alumina bricks, and corundum bricks are primarily composed of Al2O3, which categorizes them as aluminum refractory bricks.

Alkali refractory bricks, primarily composed of MgO and CaO, include:

Magnesium-based refractory bricks, primarily composed of MgO, are classified as basic refractory bricks.

2. Magnesia brick, primarily composed of CaO, is an alkaline refractory brick produced mainly from magnesite.

3. Magnesia olivine brick is a refractory brick primarily composed of MgO and SiO2.

Carbon-containing refractory bricks, primarily composed of carbon in different forms, are classified as neutral refractory bricks.

Carbon bricks, primarily composed of carbon, are manufactured from carbon-based materials.

2. Graphite carbon bricks, primarily composed of carbon, are a type of carbon refractory brick.

3. Silicon carbide bricks, primarily composed of SiC, are refractory bricks belonging to the carbonaceous compounds.

Zirconium耐火 bricks, primarily composed of ZrO2.

Zirconia Bricks

2. AZS, also known as electric melting zirconia alumina bricks.

3. Zirconia-mullite electric melting bricks.

These three types are zirconia refractory bricks, primarily composed of ZrO2.
