Applications of zirconia stabilize yttria
Zirconia stabilize yttria
Zirconia stabilize yttria is a ceramic material in which the cubic crystalline structure of zirconium dioxide is stabilized by adding yttria oxide at room temperature. Typically this type of oxide is called zirconia and atria. Manufacturing of stabilized zirconia ceramic products is a bit difficult. Its difficulty is due to the large volume change associated with the transition from tetragonal to monoclinic.
Applications of zirconia stabilize yttria
Zirconia stabilize yttria has many applications. Among the applications of zirconia stabilized with yttria are the following:
- Used in making different metal crowns without metal.
- Because of its hardness and chemical properties, it is used in the construction of the crown.
-
Applications of zirconia stabilize
- It is used as a material for non-metallic knife blades.
- Used as a refractory material in the manufacture of jet engines.
- Used as a thermal coating on gas turbines.
- It is used as a high-precision alignment for the fiber optic ferrule connection.
Used as an electrochemical material. This application is due to the ion transporting properties of oxygen in exhaust gases, pH measurement in high temperature water and in fuel cells. Other uses include the production of a solid oxide fuel cell as a solid electrolyte. In addition to preventing electron transfer, it can activate oxygen ions. To achieve the required ion conductivity, SOFC with zirconia stabilize yttria electrolyte must be operated at temperatures between 1000 and 800 ° C. The stabilized zirconia with yttria has the advantage of maintaining mechanical strength at this temperature. However, high temperatures are often associated with SOFC losses. Its high density is also used to separate the gas fuel from the necessary oxygen. In addition, the electrochemical system cannot generate electrical power.
It is also used as jewelry. The reason for this choice is its solidity and optical properties in its single liquid form. Used in water based pastes for ceramics and cements. These include microscopically stabilized milled zirconia fibers or sub micrometer particles. They are associated with the bonding of potassium silicate and zirconium acetate. The cement is made by removing the water. The ceramic material obtained is suitable for very high temperature applications. If zirconia stabilize yttria is combined with yttria materials, it can act as a warm phosphorus and a luminous material.
