All You Need to Know about Fire Clay

by Barkha Pahuja SEO/Writer Fire clay bricks are also called fire bricks, fire clay, refractory brick, fireplace brick, industrial ceramic brick, chamotte brick, and heat resistant brick. But these are traditionally called as fire clay bricks because of their simple construction from the ordinary mud. These are easily found in nature with the accurate refractory properties and with the exact ratio of alumina and silica in them.
Applications of fire clay bricks
Fire clay bricks act stubbornly, and this is why the application areas need to choose fire bricks accordingly. Accurate dimensions, crushing power, porosity, and a few other things that their application. These types of bricks are used in
Building wood fired ovens
Creating fireplaces
Different fire boxes
Linings of the wood heaters
Linings of industrial furnaces, etc.

Characteristics of a fire clay brick

Heavyweight
Dense in nature
Contains low porosity
Can be reheated numerous times
Sustains for longer times under the continuous flame

How to choose the appropriate fire clay bricks for any application?

Whenever people choose any dense refractory object or a fire clay brick for their applications, what matters the most is the amount of alumina present in it. Normally an average of 17-40% of alumina can make the composition tough and long lasting under heating.

It is the percentage of the alumina that decides the right product at the proper temperature. Here is a chart for that.

21% alumina is good for 1620 degree Celsius temperature
24% alumina is good for 1640 degree Celsius temperature
27% alumina is good for 1670 degree Celsius temperature
33% alumina is good for 1700 degree Celsius temperature
38%-40% alumina is good for 1720 degree Celsius temperature
