Refractory bricks: what it is

THE refractory bricks they are those that boast the ability to withstand very high temperatures, and by very high I also mean a thousand degrees centigrade. It is not over: the great usefulness of these building elements is also based on the fact that they are capable of withstand high thermal shocks and they do not show any failure, they do not allow themselves to undergo deformations or even to crack.

Made using clay with a high percentage of silica and alumina, i Refractory bricks in addition to being thermally resistant, they are also resistant from a mechanical point of view and they owe it to the fact that the materials that compose them have a compact and thin grain.
