Inorganic insulation materials can be used to replace fiber products for kiln insulation. Inorganic thermal insulation materials are a type of material with excellent thermal insulation properties in high-temperature environments. They are usually made of inorganic minerals, such as alumina, silicon oxide, magnesium oxide, etc.

Compared with fiber products (such as refractory fibers), inorganic thermal insulation materials have some advantages and applicability, such as:

High-Temperature Resistance: Inorganic insulation materials are generally able to withstand higher temperatures because they are composed of inorganic minerals that are resistant to high temperatures.

Resistance to vibration and mechanical stress: Due to their hard nature, inorganic insulation materials have better resistance to vibration and mechanical stress and are suitable for some environments that require higher durability.

Resistance to chemical corrosion: Inorganic insulation materials have good resistance to chemical corrosion and can be used in some applications involving corrosive gases or chemicals.

Stability: The performance of inorganic thermal insulation materials is relatively stable under long-term high temperatures and is not prone to pyrolysis, decomposition, or reduction of thermal insulation performance.

However, some issues need to be noted

Weight: Inorganic insulation materials are generally dense and relatively heavy. This may affect the design of some applications.

Thermal Conductivity: Some inorganic insulation materials may have higher thermal conductivity compared to refractory fibers and may require thicker layer thicknesses to achieve the same insulation effect.

Processing Difficulty: Some inorganic insulation materials can be relatively difficult to process and install.

Whenever possible, material selection should be based on specific application requirements, budget, and available resources. Whichever material you choose, you need to ensure that it provides the required insulating properties and durability to meet your kiln insulation needs.
