Zirconium oxide ZrO2 powder:

Zirconium dioxide, also known as Zirconia or zirconium, 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 various colors and used as a gem or a replica of a diamond.

Zirconia does not react chemically. It can be slowly attacked with concentrated sulfuric acid or hydrofluoric. If heated, it becomes zirconium carbonide. If heated in chlorine with carbon, it becomes zirconium trichloride.

Zirconium oxide has been one of the most researched ceramic materials. ZrO2 is a monoclinic crystal at room temperature but transitions to a tetragonal structure at higher temperatures. When the structure shifts from tetragonal, monoclinic, or cubic, it causes a large volume change. This can 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, is made up of seven coordinated zirconium centers. 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 an exceptional case of Zirconia. It is made up of the metastable phase of the tetragonal phase.

How does Zirconium oxide ZrO2 Powder get made?

Chlorination and oxidation

Chlorination and oxidation are one of the main methods for the production of zirconia. The chlorination process is to react zircon sand with a chlorinating agent (such as chlorine gas or hydrochloric acid) to produce zirconium tetrachloride and then react it with pure oxygen at a certain temperature and pressure to produce zirconia. The oxidation method is the reaction of zircon sand with pure oxygen at high temperatures to produce zirconia. The advantages of these two methods are that the process is simple, easy to operate, and the product quality is high. Still, the quality of the raw materials is high, and the consumption of a lot of energy.

Carbon reduction method

The carbon reduction method is a method of reacting zirconia with carbon to form zirconia at high temperatures and then reacting zirconia with pure oxygen to form zirconia. The advantage of this method is that high-grade zircon sand can be processed without the need to use a lot of energy and equipment. However, the process of this method is long, the operation is difficult, and the product quality is relatively low.

Chemical vapor deposition

Chemical vapor deposition is a method of reacting zircon sand with chlorinating agent and hydrogen to produce zirconium tetrachloride at a certain temperature and then reacting zirconium tetrachloride with pure oxygen to produce zirconia. The advantage of this method is that high-purity zirconia can be directly obtained, and the product quality is high. However, the process of this method is long, the operation is difficult, and it needs to consume a lot of energy and equipment.

Thermal decomposition method

The thermal decomposition method is a kind of high-temperature thermal decomposition of zircon sand to obtain zirconia. Zirconia and carbon dioxide were obtained by mixing zirconia sand with sodium carbonate solution for high-temperature thermal decomposition. The advantage of this method is that high-grade zircon sand can be processed without the need to use a lot of energy and equipment. However, the process of this method is long, the operation is difficult, and the product quality is relatively low.

Production Method Zirconium Oxide ZirO2 powder:

Chlorination and roasting method

Chlorination and roasting are one of the common methods for producing zirconia. First, zircon sand is reacted with chlorine gas or hydrogen chloride to form zirconium tetrachloride. Zirconium tetrachloride is then reacted with pure oxygen at high temperatures to produce zirconia and chlorine gas. Finally, the obtained zirconia is roasted to obtain the final product. The advantage of this method is that the process is simple and easy to operate, but it needs to consume the quality of raw materials is high.

Carbon reduction method

The carbon reduction method is a method of reacting zirconia with carbon to form zirconia at high temperatures and then reacting zirconia with pure oxygen to form zirconia. The advantage of this method is that high-grade zircon sand can be processed without the need to use a lot of energy and equipment. However, the process of this method is long, the operation is difficult, and the product quality is relatively low.

Plasma method

The plasma method is a method of preparing zirconia at low temperatures by using plasma technology. In this method, zircon sand is heated to a high temperature by a plasma torch, which makes it partially melt and undergoes a chemical reaction to produce zirconia. The advantages of this method are that high-purity zirconia can be prepared at low temperatures, the reaction speed is fast, and the energy consumption is low. However, the equipment cost of this method is high, and the quality of raw materials is high.

Hydrolysis process

The hydrolysis method is a method of mixing zircon sand with alkali water to produce zirconia hydroxide through hydrolysis reaction and then calcination of zirconia to obtain zirconia. The advantages of this method are simple process and low cost, but the purity of the product is low.
