Carbon Bricks: Basic FAQs are all here!


Carbon bricks, also name Co2 brick and carbon black brick, they are known for their high strength, unique heat resistance properties, and excellent thermal conductivity. But despite that, there are still many questions surrounding carbon bricks that need to be addressed. For this reason, we have compiled a list of frequently asked questions (FAQs) and answered them in this blog post. By reading on, you will learn what carbon bricks are, their composition, and the different types of carbon bricks, among other things.

What is a carbon brick?

Carbon bricks are high-quality refractory bricks that are made of carbon-rich materials. They are known for their high density, high thermal conductivity, excellent insulation properties, and resistance to high temperatures. As a result, carbon bricks are ideal for use in high-temperature environments such as blast furnaces, incineration plants, and glass-melting tanks.

What are carbon bricks used for?

Carbon bricks are used in many applications requiring high temperatures and exceptional strength. They find use in steel, glass, and ceramics production. Additionally, carbon bricks are used in heating elements, fuel cells, electrodes, and even electronic components.

What is the composition of carbon bricks?

Carbon bricks are made from various carbon-rich raw materials, including graphite, carbon black, petroleum coke, and coal tar pitch. The exact composition will vary depending on the bricks’ desired strength, density, and thermal conductivity properties.

What are graphite bricks?

Graphite bricks are a type of carbon brick made purely from graphite. Graphite bricks have high thermal conductivity, excellent electrical resistivity, and good erosion and oxidation resistance properties. They are used in the metallurgy, glass, and chemical industries.

What are the different types of carbon bricks?

The different types of carbon bricks vary in composition, strength, size and shape, and are designed to suit a wide range of applications. The main types of carbon bricks are high-density carbon bricks, low-density carbon bricks, and graphite bricks. High-density carbon bricks are commonly used in blast furnaces, while low-density carbon bricks are used in incinerators and oxy-fuel burners.

What is the size and density of carbon bricks?

Carbon bricks come in different sizes and densities, depending on their intended use. Typically, carbon bricks may range from 230mm to 500mm in length and width and up to 600mm in height. The density of carbon bricks ranges from 1.4g/cm3 to 2.1g/cm3.


In conclusion, carbon bricks are commonly used refractory bricks known for their strength, thermal conductivity, and high resistance to heat. They find use in a broad range of global industries, including steel, glass, and ceramics production. Understanding the composition, types, size, and shape is critical in selecting the right carbon bricks for specific applications.
