Zirconium dioxide (chemical name: ZrO2), is zirconium's main oxide. It's a powder with an odorless, white color.
Pebble size: 20nm - 200nm
Zirconium oxide ZrO2 powder:
Zirconium dioxide also known as Zirconia or zircon (not to confuse with zircon) is a white crystalline oxide of zirconium. The mineral baddeleyite, which is a monoclinic crystal structure, is its natural form. The cubic zirconia dopant stabilized cubic structured zirconia can be made in different colors and used as a gem or a replica of a diamond.
Zirconia does not react chemically. Concentrated sulfuric acid or hydrofluoric acid slowly destroy it. If heated, it becomes zirconium carbonide. If heated in chlorine with carbon, it becomes zirconium trichloride.
Zirconiumoxid has been one of the most researched ceramic materials. ZrO2 is a monoclinic crystal at room temperature, but transitions to tetragonal at higher temperatures. When the structure shifts from monoclinic, to tetragonal, to cubic it experiences large volume changes that cause cracking upon cooling at high temperatures.
It is possible to identify three types of phases. It is common to see higher symmetry at higher temperatures. The cubic phase is stable for a very small number of the yttrium and calcium oxides. Cubic is also the case for rare minerals like tazheranite (Zr Ti and Ca)O2. TiO2 has six-coordinated Ti in all phases. Monoclinic Zirconia, however, has seven coordinated zirconium center. This is due to the difference in size between the zirconium and titanium atoms.
ZrO2 bands are dependent upon the preparation and phase. Typical estimates range from 5 to 7 eV. Tetragonal zirconia Polycrystal (TZP) is a special example of zirconia. It is a form of zirconia made up of the metastable and tetragonal phases.

Zirconium oxide ZrO2 powder performance:
Inactive zirconium dioxide chemically has high melting points, high resistanceivity and low coefficients of thermal expansion. This makes it an important ceramic insulating material, ceramic sunscreen material, artificial drills, as well as a main component of artificial drilling machines. raw material. The band gap lies between 5-7eV and 5-8eV.

How does Zirconium oxide ZrO2 Powder get made?
Stabilly Zirconia is used as an industrial refractory and is where most electric mete comes from. To the zircon fuse, carbon and stabilizable Calcium oxide were combined. The solution was then used to produce a solid solution. Finally, stably Zirconia, which was made from the combination of the calcium and zirconia, was used for forming a solid mixture. The majority of stable, partially stabilized zirconia used for fine ceramics was prepared using wet.
It is also the most popular and widely used method. Pure water is used to dissolve the purified chloride Zirconium. Filter the insoluble material, adjust the concentration of the solution for zirconium, add cerium chloride solutions (or any other rare earth metals or alkaline chloride solutions), and finally add ammonia water medium and precipitation. Hot water was used to wash the precipitate. Then it was dried, calcined and filtered. You can make ultrafine zirconia dust by treating the calcined material.
To control how much stabilizer is used, partial stabilization of zirconia can be done. This is necessary to maintain stability. Partially stabilized zirconia is strong and resistant to thermal shock, so it has a wide range of applications in structural ceramics.
Zirconium Oxide ZirO2 powder:
Metal zirconium or zirconium compound, fire bricks/crucibles, high frequency ceramics, and abrasive material, as well as ceramic pigments. Zirconates can be used for piezoelectric ceramic products and daily ceramics.
Zirconia fibers can be described as a polycrystalline refractory fibre material. Because of its high melting temperature, non-oxidation, and other excellent high-temperature characteristics, ZrO2 fibers have higher use temperatures that other refractory fibres like alumina, mullite, or aluminum silicate fibers. Zirkonia fibers can be stored for extended periods in extremely high temperature oxidation conditions above 1500°C. The highest temperatures are as high at 2200°C and as low as 2500°C. Even 2500°C is able to retain a full fiber shape. Fiber material.
A plasma spray zirconium oxide thermal barrier coating has made tremendous progress on-air gas turbines. This has been applied to turbine sections of gas turbines in a limited range. The coating is capable of reducing the temperature from 50 to 200°C of the hot-cooled member. This can greatly improve its durability, temperature, and maintain it at a lower temperature. This improves the engine's performance.
Zirconium Oxide Ceramic Material
The refractive value of zirconia, which is also large and has high melting points, is very corrosion resistant, making it a popular choice for the kiln sector. The products of piezoelectric ceramic are filters, speakers and ultrasonic detectors. You can also find zircon tubes, industrial ceramic glazes and zircontiles for precious metals smelting. The nano-grade zirconia is also used to polish, glaze, and create high-temperature pigment matrix materials.
Additionally, zirconia may be used for the production of enamel, white-hot gas masks and the white glass refractorycrucible. X-ray photography. Grinder material. The light source lamp is made from thick circuit capacitive material and piezoelectric crystal transducer formulations for infrared meters.
