The zirconia that has the zirconia material also has the element Hafnium. The zirconia is in the form of crystal at standard room temperature and turns into cubic form from the tetragonal form as the temperature rises. So, the zirconia differentiates under such conditions. This state is referred to as cubic crystal form and has the look of diamond. This structure is termed as zircon which is commonly used to make jewelry. In the chemical terms, it is defined as zirconium silicates ZrSiO4 which needs adding stabilization, magnesium oxide, tetragonal and yttrium oxides. When a restoration is made using zirconium, it is necessary to develop dental materials in high quality and large number. The zirconia materials allow to have robustness and harmony is marginal form and also support to present dental ceramic and wax material works. The zirconia materials allow to make standard crowns using computer-assisted programs and are also suitable for the digital veneering.
The concept of zirconium is strengthened through oxide. The zirconium materials have an important role in oxide ceramics and lead the way for the concept of high strength and chemical stability to be at the highest level. The zirconium materials produced using the CAD/CAM technology are known for their natural appearance. The zircon is included in the group D of the standard periodic table and defined as a transition element. The density of zirconium is 6.49 g/cm. The melting point for the zirconium is 1852. The zirconia materials are found in white color and solid state. The zirconium does not react with water and is inactive to acids. The zirconia materials, which are inactive to acids, do not react with the alkali solutions neither.
