Refractory | Millers & Base Minerals | African Pegmatite

Glass powder, made entirely of recycled materials, can replace the silica traditionally used in refractory production. Due to the nature of the industry, it’s vital that your refractory materials meet the specifiions required by your appliions.

Products | Ashapura

Refractory Mortars amongst Monoliths are basically finely ground refractory materials, which become plastic when mixed with water. These are used to bond the brickwork into solid unit, to provide cushion between the slightly irregular surfaces of the brick, to fill up spaces created by a deformed shell, and to make a wall gas-tight to prevent penetration of slag into the joints.

Ceramic forming techniques - Wikipedia

Materials prepared for dry powder forming are most commonly formed by "dry" pressing in mechanical or hydraulic powder compacting presses selected for the necessary force and powder fill depth. Dry powder is automatically discharged into the non-flexible steel or tungsten carbide insert in the die and punches then compact the powder to the shape of the die.
