What is the classification of lightweight thermal insulation bricks

Lightweight insulation refractory bricks. Refers to refractories with high porosity, low bulk density, and low thermal conductivity. It includes high-aluminum heat-insulating lightweight refractory bricks, clay-based heat-insulating lightweight refractory bricks, diatomite heat-insulating lightweight refractory bricks and floating beads These four categories of bricks.
