What is zirconia or zirconium oxide?
Zirconium oxide with the chemical formula ZrO2 is one of the most widely used minerals that we intend to describe in detail. This material is a crystalline white oxide of zirconium, which, of course, can be produced in various colors. Zirconia material was first used in the medical industry in 1969, and due to its very high mechanical properties and very good tribological properties, we saw an increase in its use in various industries day by day. This white solid crystalline material is currently used in the dental industry as a ceramic dental crown. This material is usually transparent and has a monoclinic prismatic crystal structure and is known as one of the rarest and rarest minerals in nature.
Zirconium oxide is also known as ceramic steel and is used as a restorative material in many industries due to its ideal mechanical properties. Stained zirconia is one of the types of zirconium, which is also known as cubic zirconia due to its cubic structure. The production of this zirconia is artificial and used in the jewelry industry as non-original or fake diamonds.
Methods of producing zirconium oxide
As it was said, zirconium oxide is a very rare and rare mineral in nature, but due to its special chemical and physical properties, it is known as one of the most demanded minerals in the world. For this reason, today, its production by artificial methods in It is happening all over the world. In general, it is possible to produce zirconium oxide in three possible phases, of course, the type of phase will largely depend on the temperature of the production method. These three possible phases of zirconium oxide production are:
Monoclinic
cubic
tetragonal
The production of zirconium oxide is done by the method of thermal separation or the same method of heat treatment, and of course, if this process is done in pure form, it will probably cause sudden phase changes. These sudden phase changes will always cause cracking or breakage of materials, and to prevent this from happening, stabilizers such as yttrium oxide, magnesium oxide, and calcium oxide should be added to completely stabilize the structure of the material. Zirconia oxide is also produced through the decomposition of zircon rock and by fusion using compounds such as calcium oxide, sodium carbonate, calcium carbonate, sodium hydroxide and magnesium oxide.

Uses of zirconium oxide
The unique features and characteristics of zirconium oxide have made us witness the widespread use of this mineral in various industries today. Among the most important applications and uses of zirconium oxide are:
Medical industry
Dental industries
Electronics manufacturing industries
Pigment production industries
Ceramic industries
Refractory production industries
Fuel cell production industries
Marine pump manufacturing industries

Can be used as a protective layer in mechanical parts
Jewelry industry
And…
The things mentioned are only a small part of the applications of zirconium oxide that we have mentioned, and every year we see an increase in the applications and uses of the synthetic type of this mineral in various industries.

Physical and chemical properties
Now that you are familiar with the production methods as well as the applications of zirconium oxide, we are going to describe its special physical and chemical properties. It is necessary to know that zirconium oxide is chemically completely neutral and dissolves in some acids, especially sulfuric acid. This substance has many physical properties, including the following:
It has very high mechanical resistance, especially against cracking and mechanical stress
Having high resistance to high heat (with a melting point of 2700 degrees Celsius)
It has a very high expansion coefficient
Having very low thermal conductivity
Very high chemical resistance
Having very high flexibility
Very strong
It has very good biocompatibility
Abrasion resistant
Introducing products of the zirconium oxide family
Currently, using modern technology, the combination of zirconium oxide with other chemicals is also used in some industries. The products of the zirconium oxide family have wide applications in various industries, and day by day we see the combination of this mineral with other chemicals for special uses in various industries. Among the most important products of the zirconium oxide family are:
Zirconium silicate
Zirconium sulfate
Zirconium oxynitrate
Zirconium oxychloride
Zirconium acetate
Zirconium carbide
Today, some alloys of this material are used in nuclear energy industries to cover fuel rods in nuclear reactors.
