Zirconia Ceramic Sheet

Under normal temperature use, zirconia ceramic sheet has very good mechanical strength in industrial fine ceramic products. The thermal expansion rate of zirconia plate is similar to that of metal, and it is particularly suitable for use in combination with metal materials. Zirconia ceramic plates have low thermal conductivity and high toughness. Zirconia (Zirconium Oxide & ZrO2) Ceramic is a material that overcomes the shortcomings of ceramics that are too brittle and fragile.

The advantages of zirconium oxide sheet are as follows:

(1) High hardness, high toughness, high bending strength, the density of zirconium oxide plate is between 5.95-6.05g/cm³, the main superhard ceramic products (alumina, silicon carbide, silicon nitride, zirconia) produced by UNIPRETEC are between these three, ZrO2 Zirconia has the highest toughness, over 8MPa•m1/2.

(2) High wear resistance, low friction coefficient, wear resistance is 15 times that of alumina ceramics, and the friction coefficient is only 1/2 of aluminum oxide ceramics. After grinding, the surface finish of ZrO2 plate is higher, reaching Ra 0.05um, It is mirror-like, extremely smooth, and has a smaller friction coefficient.

(3) Good insulation, strong corrosion resistance, no static electricity, high temperature resistance, excellent heat insulation performance, and thermal expansion coefficient close to steel.

(4) Zirconia ceramics are self-lubricating, which can solve the pollution and inconvenience of adding lubricating media.

Technical Characteristics

With the development of advanced ceramics in the various industries in recent years, the application field of zirconia ceramic has also undergone a major change. From the past application of metallurgical chemical industry as a fire-resistant and anti-corrosion material, it has now been applied to automotive energy, digital home appliances, and medical equipment, industrial electronics and many other industries as structural ceramics, bio-ceramics and electronic ceramics.
