Refractory bricks, or fire bricks, are specialized ceramic materials used in fireboxes, furnaces, fireplaces, and kiln linings. These bricks are engineered not only to withstand extreme heat but also to conserve energy through their low thermal conductivity.

Given their exposure to intense thermal, chemical, and mechanical stresses in environments like furnaces or wood-fired kilns, choosing the right refractory bricks is critical. Poor selection can result in frequent equipment failures, costly downtimes, and increased safety risks.
