1.High – temp resistance: Withstands extreme heat stably. 2.Low thermal expansion: Resists cracking from temp changes. 3.Strong corrosion resistance: Defends against acidic and alkaline media. 4.Good thermal conductivity: Transfers heat efficiently.
Carbon bricks are used in blast furnaces for iron – making, lining reactors in chemical plants, and as linings in non – ferrous metal smelting furnaces due to their unique properties.
