Introduction
Clay insulation bricks, also known as lightweight fireclay bricks or insulating firebricks, are a type of insulating refractory material made primarily from fireclay, which consists mainly of hydrated aluminum silicates.
They have low bulk density, low thermal conductivity, and good thermal shock resistance, making them suitable for use in various high-temperature applications where thermal insulation is essential.
