Refractory bricks are available in numerous types to suit different applications. They vary based on their precise heat handling capacities and arrangement, as well as their structural and chemical formulations. With the accurate sort of bricks used, they are tremendously useful in heat control in a heater, fireplace, furnace, or similar situation.

Using suitable refractory bricks for applications means a low maintenance, lucrative, and safe and sound heating system for multilateral performance. But the defectively chosen bricks for the boiler can mean bigger workplace accidents, regular equipment failures, and recurrent downtimes.

A few major types of bricks are:


Bricks in these classes are manufactured in a mixture of alumino-silicates. The maximum quality bricks are made with aluminium in 90% to 95%. These bricks, with the superior concentration of alumino-silicates, are more effective. The less effective bricks have much lower concentrations of aluminium and are not as flexible at standing up to the temperature of the flames. Also, this type of element is hard-wearing to defend against corrosion from chemicals, excellent abrasion-proof and high wear-resistance.

Silicon carbides

Silicon carbides are a realistic choice when in an atmosphere with very high heat and high abrasion resistance. This type of substance can give higher durability. Also, its elevated strength property means it has the aptitude to last longer than most other types of liners.

Ceramic bricks

Ceramic bricks are useful with their vast features. Ceramic is a realistic choice for its elevated heat tolerance levels, abrasion confrontation, and outstanding wear. Plus, ceramic materials are fairly easy to shape to a definite shape to make it reasonably straightforward to match a precise use or application.

Working temperature range

The utmost temperature range refractory bricks are designed to handle varies with the meticulous unit. For instance, alumino-silicates are set as an average duty brick and are likely to work up to a working temperature of 900 degrees Fahrenheit. These bricks may be made up of 50% silica and 35% alumina. It is proposed to work in an atmosphere that heats up and cools down rapidly. In the advanced temperature range of up to 1500 degrees Fahrenheit, the substance of alumina is likely to increase to 50% or more. They are sensible for a heater that needs a steady high-heat application.

Important applications and huge varieties

Fire bricks are used for a broad range of purposes. It finds application in various sectors, including aluminium and steel plants. Thermal shields in space shuttles are made up of these bricks. Pizza ovens are also made with these kinds of bricks.

Refractories manufacturers in India offer a variety of types of bricks through their online stores which include silicon carbide blocks, zircon blocks, acid-proof blocks, constructional high alumina blocks, low alumina blocks, industrial high alumina blocks, low alumina blocks, fly ash blocks, ceramic and tailored blocks. In addition to these varieties, there are electric-resistant bricks available in many industries around the world. Most of these elements are accessible at comprehensive price rates too.

Nowadays, fire bricks are created by refractory exporters in Kolkata using a range of advanced machinery. There are diverse brick manufacturing machines available in many online stores at various rates.
