Fire brick is a generic term that encompasses any brick that can withstand repeated heating and cooling at various temperature ranges.
Made out of non combustible material masonry brick veneer etc.
102 mm brick wythe alone provides a 1 hr fire resistance rating for the exterior surface of the wall.
Additionally fire bricks must be able to withstand different atmospheres provide various structural or insulating qualities and due to the difficulty in cutting them must be available in a variety of shapes to add flexibility to kiln design and construction.
This is done by extrapolating from known fire resistance periods for a given thickness of wall.
Brick veneer wall assemblies with wood stud backing routinely attain fire ratings of up to 2 hr.
Since the primary ingredient in brick is clay which is fired to around 20008 f it is a non combustible material.
