🧱 color and shape

The color of firebrick is naturally white. But it is possible to make different colors in such a way that the stains are mixed inside the watery substance (slurry) so that the brick is colored during the manufacturing process; Some popular colors used for facades include espresso, moss green, red, and black. The shape of refractory bricks used in building facades is uniformly rectangular, while ordinary bricks may have different shapes. 🧱 thermal conductivity The thermal conductivity of ordinary bricks is much higher than refractory bricks. Firebricks can withstand high temperatures because materials such as ceramics, ferric oxide and other chemical additives do not absorb and transmit high temperatures. Low thermal conductivity makes firebricks a good option for wall insulation and provides more insulation than ordinary bricks. Due to high heat absorption and low thermal conductivity, refractory bricks have become a suitable option for places such as furnaces, cement industries, and steel industries. Being denser, more resistant to wear and damage are among the characteristics of refractory bricks.
