What are the types of refractory materials?

There’re various types of refectories’ available now. They differ in the structural and chemical makeup and heat threshold capacities. When rightly used, your heating facilities reap the gifts of an effective heat containment device. The correct refectory content well makes a safe, cost efficient as well as low maintenance heating system which delivers regularly. The incorrect option of the refractory content comes with delays, tools failure and the potential for the wound (injury).

What are the types of refractory materials?

Refractory Materials (contents) are stored primarily based on their chemical strength and behavior. Contents which can withstand specific sorts of slag (noxious (toxic) waste of metal burn off) and particularly valued for their durability. Here’re the main types of refractory contents and their uses:

  • Alumina

Alumina refectories’ are used mainly in and around blast lime, furnaces, glass tanks, cement, and ceramic kilns and for melting a range of metals.

  • Fireclay

Fireclay brick is very durable and reasonably priced, making it the most ordinary type of refractory brick applied in kilns, furnaces, stoves, and kilns.

  • Silica Brick

Silica brick is extremely strong, even at temperatures that move toward their fusion spot. A range of types of silica brick are applied widely in the steel and glass industry.


The physical properties of MAGNESITE brick are literally poor, with their rate mainly in their resistance to iron-rich slags and lime. Magnesite refectories’ are vital to the steelmaking procedures.

  • Chromite

Chromite refectories’ (chrome – MAGNESITE) are applied for in high level temperature furnaces. These contents can withstand corrosive gases and matter, making them very suitable for use in steel metal as well as similar functions.

  • Monolithic

The monolithic refectory is the umbrella period to describe the entire un-shaped refractory items, loaded as a powder mixed with a fluid that hardens to shape a solid mass (same to poured  or sprayed concrete.)

  • Zirconia

These refectories’ have extremely impressive power at room temperature, a power that is maintained up to temps reaching 15000 C. Zirconia refectories’ does not react with fluid metals and molten glasses. This creates them particularly helpful in glass furnaces.

Professional Guidance

Without wide knowledge of the sorts of refractory materials or contents, you place yourself at serious risk of selecting the incorrect one. Sound, expertise guidance is extremely vital to making the correct option your refectories’ needs.
