Silica bricks are the main species of silica-based refractories, where the mass fraction of SiO2 is not less than 93%. Silica brick is a typical acid refractory bricks, the acid slag has a good resistance to Al2O3, FeO, Fe2O3 and other oxides also has good resistance, but the resistance to alkaline slag is poor, easy to CaO, K2O, Na2O and other oxides and damage.
Features:
1.Good acid and erosion resistance, powerful anti high-temperature strength.
2.Soften melting temperature is 1620~1670 °C.
3.Low thermal shock resistance.
4.Natural silica as raw material, plus regular mineralizer.
5.Ensure good bonding and structural strength of furnace.
6.Good heat resistance and long service life.
Application:
1.Glass melting furnace, ceramic frit kiln, sodium silicate furnace, soaking furnace, ceramic kiln, etc
2.Coke oven's coking chamber, combustion chamber walls, steel open-hearth's regenerator and sediment chamber, etc.
3.Load-bearing parts of high temperature hot air furnace and acid open-hearth furnace roof, etc.

High alumina description generally means content of alumina percentage is higher than 45. Alumina is one of the most chemically stable oxides, and it offers excellent hardness, strength and spalling resistance. Alumina refractories are suitable for lining furnace operating up to 1850C. Alumina refractories have the advantages of a high resistance in oxidizing and reducing atmosphere and is extensively used in heat processing industries.
