company news about Geometry of refractory bricks having a regular crystal

Geometry of refractory bricks having a regular crystal, rather than the crystal is not, because the composition of the crystal particle is regularly arranged in the space of a certain point, the formation of spatial lattice (lattice), rather than the arrangement of the crystal particleIt is irregular and no rules. Crystal has a fixed melting point. When the crystal is heated to a certain temperature, that is, the melting point, the crystal begins to melt, but the crystal material has not been fully melted before the heating, the temperature is no longer rising.
