Fireclay bricks are a type of refractory brick made from high-quality clay materials. Their physical properties may vary depending on the manufacturing process and the specific application, but here are some typical ranges:
1.Density
The apparent density of fireclay bricks is typically in the range of 2.0-2.3 g/cm³, which means they have a relatively high weight compared to their size.
2.Porosity
Fireclay bricks have low porosity, usually in the range of 15-25%, indicating good resistance to penetration by gases or liquids.
3.Thermal conductivity
The thermal conductivity of fireclay bricks is generally low, ranging from 0.6-1.0 W/m·K at room temperature, which means they offer good thermal insulation.
4.Compressive strength
Fireclay bricks exhibit high compressive strength, typically ranging from 100-150 MPa, indicating excellent resistance to crushing under load.
5.Refractoriness
Fireclay bricks have a high refractoriness, typically ranging from 1580-1750°C, meaning they can withstand extremely high temperatures before softening or melting.
Overall, the physical properties of fireclay bricks make them an ideal material for use in high-temperature applications, such as furnaces, kilns, and other industrial equipment that require excellent resistance to heat, wear, and corrosion.
