Standards and Applications of Insulating Fired Bricks

Insulating Fired bricks are advanced refractory materials known for their exceptional thermal insulation properties and high-temperature stability. These bricks find extensive use in industries where high temperatures and thermal efficiency are critical, such as lithium Battery,ceramic, metallurgy, petrochemical, aluminium and glass manufacturing etc..

Standards for Insulating Fired Bricks

The quality of insulating fired bricks is governed by several international standards. These standards ensure that the bricks meet specific requirements related to their physical, chemical, and thermal properties.

ASTM C155: Specifies the method for determining the density and porosity of refractory products. This ensures that the bricks have a controlled porosity for optimal thermal insulation.

ISO 10081: Provides guidelines for the chemical analysis of refractory materials, ensuring that the mullite bricks have the desired chemical composition for high-temperature stability.

ASTM C201 and ISO 8894-2: These standards outline methods for measuring the thermal conductivity of refractories, which is critical for assessing the insulation performance of insulating bricks.

Physical Properties:

The bricks should have a uniform density and porosity to achieve optimal thermal insulation. The standard ASTM C155 specifies the density and porosity limits for refractory bricks.

Chemical Properties:

The chemical composition of the bricks should be controlled to ensure their resistance to corrosion and high-temperature stability. Standards such as ISO 10081 provide guidelines for the chemical analysis of refractory materials.

Thermal Properties:

The thermal conductivity are critical for their insulation performance. Standards like ASTM C201 and ISO 8894-2 specify methods for measuring these properties.
