Firebricks, also known as refractory bricks, are specialized building materials designed to withstand high temperatures and harsh conditions. These bricks are made from heat-resistant materials, typically ceramic or silica-based compounds, that can endure extreme heat without losing their structural integrity. Firebricks find extensive use in industries like metallurgy, glassmaking, ceramics, and more, where they are used to line furnaces, kilns, and other high-temperature equipment. Their ability to withstand intense heat and maintain their shape makes them essential for creating durable and efficient heat containment systems.
