A fire brick, firebrick, or refractory is a block of ceramic material used in lining furnaces, kilns, fireboxes, and fireplaces. A refractory brick is built primarily to withstand high temperature, but will also usually have a low thermal conductivity for greater energy efficiency.
There are mainly three varieties of refractory bricks;
a) Acid Refractories
i. Ordinary Fire Bricks
ii. Silica Bricks
iii. Ganister Bricks
b) Basic Refractories
i. Magnesite Bricks
ii. Dolomite Bricks
iii. Bauxite Bricks
c) Neutral Refractories
See lessi. Chromite Bricks
ii. Carborundum
iii. Chrome Magnesite Bricks
iv. Spinal Bricks
v. Forsterite Bricks
