High quality industrial Zirconia ceramic pin used for machine
1. Description
Zirconia ceramic Uses Yttria-stabilized zirconia powder as raw material, so the refractoriness, etch resistance,
Chemical stability ofit are much higher than alumina articles.
The highest temperature of zirconia needle is 2200 degrees, is
mainly used in melting metal, good thermal stability.
Zirconia pin, owning high temperature stability,is an ideal high
temperature refractory products for experiment.
Zirconium dioxide melting point is higher than zirconium, up to 2700 °C, is one of the best fireproof performance materials in the nature.Its thermal performance is poor, but the conductive ability and corrosion resistance are very strong, It won't have effect on molten metal, such as aluminum, iron, nickel, platinum, silicate and acid slag even if heated to 1900 degrees celsius.
Thus it can be used to create melting metal crucible, fireproof
tube, heat resistant glass and heat resistant enamel, etc.
Adding zirconium dioxide into enamel and glass can make them to
enhance the ability of resistance to acid, alkali corrosion.
2. Characteristic:
For zirconia ceramic, it has many featutres as follows.
1. High strength
2. High fracture toughness
3. High hardness
4. Wear resistance
5. Good frictional behaviour
6. Non-magnetic
7. Electrical insulation
8. Low thermal conductivity 9Corrosion resistance in acids and alkalis
Zirconia ceramic has the best hardness and wear resistance, it is more and more widely used in many fields,we love this material, it plays more and more important role in industry ceramic, and many company need products made of this material. This is really good material, but price is also not cheap, raw material is very expensive, really good.
