Refractory Bentonite


Refractory Bentonite

Bentonite is commonly used in refractories due to its unique properties, which can enhance the performance and characteristics of refractory materials. Refractories are materials designed to withstand high temperatures and harsh conditions, making them essential in various industrial applications, including metallurgy, ceramics, and glass manufacturing.


  • Binder: Bentonite acts as a binder in refractory formulations, helping to hold the refractory materials together and maintain their shape and integrity at high temperatures. It provides plasticity and cohesion to refractory mixes, allowing them to be molded into various shapes and forms before firing.
  • Plasticizer: Bentonite serves as a plasticizer in refractory compositions, improving their workability and forming characteristics. It enhances the plasticity and moldability of refractory mixes, making them easier to handle and shape during installation and construction.
  • Moisture Control: Bentonite helps control the moisture content of refractory mixes, ensuring proper hydration and setting of refractory materials. It prevents excessive drying or cracking of refractory products during manufacturing and installation, leading to improved strength and durability.
  • Thermal Stability: Bentonite imparts thermal stability to refractory materials, enhancing their resistance to high temperatures and thermal shocks. It helps minimize thermal expansion and contraction of refractory products, reducing the risk of cracking and spalling under extreme heat conditions.
  • Alkaline Activation: Bentonite can undergo alkaline activation processes to further enhance its binding and bonding properties in refractory applications. Alkaline activation increases the swelling capacity and adhesive strength of bentonite, improving its effectiveness as a binder in refractory formulations.
  • Refractory Coatings: Bentonite-based refractory coatings are applied to the surfaces of refractory bricks and linings to protect them from oxidation, corrosion, and erosion. These coatings form a protective barrier that extends the service life of refractory materials and enhances their resistance to chemical attack and wear.
  • Packaging – 25 kg, 50 kg, 1mt Bags or customized packing as per requirement.
