High temperature resistance refractory Zirconia crucible
99.9% high purify Zirconia crucible bulk density is 6.00, mainly used in melting metal, have good thermal stability.high temperature stability ,the highest working temperature is 2200 degrees, i
Zirconium dioxide melting point higher than zirconium, can reach up to 2700 ℃, is fireproof performance is one of the best materials in the nature.
The thermal performance is poor, but the conductive ability is very strong,
Corrosion resistance ability is very strong, even if heated to 1900 degrees Celsius or higher
also won't react with molten metal, such as aluminum, iron, nickel, platinum, silicate and acid slag.Thus it can be used to create melting metal crucible, fireproof, heat resistant glass tube and heat resistant enamel, etc.
Add zirconium dioxide in enamel and glass can make them to enhance the ability of resistance to acid, alkali corrosion.With zirconium dioxide high temperature furnace lining, volume will not increase a lot after heating, the temperature changes little impact on it, the furnace will not produce due to the heat bilges cold shrink crack, can greatly prolong the life of the stove.With zirconium dioxide as refractory material, adding 5% of the calcium oxide as a stabilizer, its heat resistance than alumina high 500 degrees, three times higher than that of before adding insulation ability.Added white zirconium dioxide into ceramic, can make the ceramic white light, heat, strength also increased, with this kind of ceramic manufacturing high temperature insulation porcelain, insulating ability is very strong, expansion coefficient is small.
Case: can according to customer demand customize various non-standard shaped zirconia crucible!
