Mostly, normal refractory brick created of natural fire clay is as good as acid brick, but if additional acid resistance is required then an additional amount of silica is added to on fire clay which may range up to 97% of its composition.. For binding bases, 1 to 2% lime may be added on.Acid bricks are burnt at large temperatures for lengthy periods.. 2. Ordinary Refractory Brick

The refractory cement is a type of newly developed material that has excellent heat-resistant performance and is widely used in the industrial field. The most common refractory cement is calcium aluminate cement (or high alumina cement), which is a kind of hydraulic cementitious material made by grinding the aluminate cement clinker.
Refractory mixes are mixed with a minimal amount of water (up to 10 %), then pressed into steel moulds under pressures from 3.4 MPa to 10.3 MPa by hydraulic presses or compressed air rams. Drying and firing Wet bricks from moulding or cutting machines contain a large quantity of moisture, depending upon the shaping process.
EXTREMELY TOUGH MATERIAL FOR CERAMICS AND REFRACTORIES. Chamotte—also known as 'grog', 'firesand' or "fireclay" —is calcined clay containing a high proportion of alumina. It is produced by firing selected fire clays in a rotary kiln to temperatures between 1,400°C and 1,600°C, before grinding and screening to specific particle sizes.
