Our top fireproof minerals
Fire-resistant materials play a crucial role in modern construction, infrastructure, and industrial applications. At LKAB Minerals, we offer a range of high-temperature and refractory minerals designed to enhance fireproofing capabilities in various industries. But which minerals provide the best fire resistance, and how do they contribute to safer, more durable applications?
The importance of fireproof minerals
Fireproof minerals are essential for applications where high heat resistance is required, such as refractory linings, foundries, ceramics, and industrial coatings. These minerals must withstand extreme temperatures without breaking down, making them ideal for industries that rely on thermal stability and durability. Whether used in fire-resistant panels, industrial kilns, or insulation materials, these minerals ensure longevity and safety in high-temperature environments.
Key fireproof minerals from LKAB Minerals
Andalusite is an alumino-silicate mineral widely used in refractory linings for furnaces and kilns. It offers excellent thermal stability and resistance to thermal shock, making it a preferred material for industries that require high heat endurance. As a naturally occurring mineral, Andalusite enhances energy efficiency by reducing heat loss in industrial applications.
Fused Alumina, or aluminium oxide, is produced in an electric arc furnace and is known for its exceptional hardness and ability to withstand extreme temperatures. It is commonly used in high-performance refractories, abrasives, and fireproof coatings, ensuring durability in harsh environments.
Aluminium Trihydrate or ATH is a key ingredient in fireproof coatings, polymers, and construction materials. When exposed to heat, ATH releases water, which helps suppress flames and prevent the spread of fire. This makes it a valuable component in fire-resistant panels, electrical cables, and insulation materials.
Olivine is a magnesium iron silicate with a high melting point and excellent thermal stability. It is used in foundry applications, refractory linings, and high temperature casting due to its ability to withstand extreme heat without degrading.
Refractory-grade Bauxite is calcined at temperatures above 1600°C, producing a dense and thermally stable material. It is a key ingredient in the production of castables, bricks, and other refractory products designed to endure prolonged exposure to high temperatures.
Applications of fireproof minerals
These minerals are widely used across industries that require extreme heat resistance, including:
- Construction: Fireproof panels, high-performance concrete, and insulation materials.
- Foundries and refractories: Linings for furnaces, kilns, and casting applications.
- Industrial coatings and polymers: Flame-retardant coatings for enhanced safety.
- Energy and infrastructure: Heat-resistant materials for power plants and heavy industry applications.
