The following are the qualities of Zirconia

#The following are the qualities of Zirconia:

The melting point of pure zirconia is 2650 ° C. But the melting point of commercial zirconia ranges from 1800 ° C to 2750 ° C. The relative importance of zirconia ranges from 4.0 to 5.61. Its relative importance depends on the purity and incineration temperature. Zirconium oxide can be used with selenium, alumina, silica and chromite. Its relative importance depends on the purity and incineration temperature. Zirconium oxide can be used with selenium, alumina, silica and chromite.


# Zircon Refactories:

Zirconium silicate (ZrSion) is called zircon. The characteristics of zircon refractory bricks are given below. Zircon refractories can be used up to 24006 C in oxidized state. It is less volatile at high temperatures, excellent thermal shock resistant. It is 50% to 90% alumina
Safe up to 1800 ° C with chrome, chrome magnesite, ferrite and silica. It is safe up to 1550 ° C with fire bricks. At high temperatures it has low quality electrical resistive properties. It does not change the granules of acid refractories. It is highly resistant to molten metals, except in the case of excessive corrosion. It is resistant to borosilicate glass meta phosphate sodium chloride, zinc chloride potassium pyro 'sulphate. It is resistant to sodium pyru sulfate. It is attacked by sodium carbonate and sodium chloride fluoro cryolite, molten barium sulfate and tetra-sodium pyrophosphate.
