company news about The process of refractory bricks

Refractorie bricks are materials that are formulated to retain their shape and tensile  strength in the presence of extremely high temperatures.Today, most refractory bricks  are made with aluminum and silicon oxide, magnesium, zirconium, silicon carbide and  graphite.
Ceramic formulation and adjustment technology can be approached on different levels:  The pure oxide, the oxide in the presence of others with which to interact, the  mineral, the material, the recipe and the process.
The materials we use are powders and we assess their physical presence on that level.  However these powders are generally composed of microscopic mineral particles (except  for frits of course). In many materials these particles are homogeneous,
Some oxides exist as physical powders we can add to a recipe, but oxides in the  context of glaze chemistry is more of a theoretical concept
Oxide chemistry is not normally factored into understanding what bodies do when fired,  it is difficult to draw relationships between the chemistry of vitreous bodies and  their physical fired properties. This is because bodies are not melted during firing  as are glazes, normally firing creates conditions of crystal growth in the body.  Chemistry needs to be put in context with the other levels. For example, consider a  glaze that is crazing: If it contains a lot of Na2O, then it has a high thermal  expansion, that is almost certainly the cause.

In the home, refractory materials may be found in fire brick and around heating  systems. Some types of refractory products are designed to withstand corrosive  chemicals, such as various types of acid.
