How serious are fertility problems today? People don't want to give birth,can't afford it, and can't give birth that has become the "three mountains".
The problem of childbirth is related to the people's livelihood. Whether a country can prosper or not depends on the population. I saw a set of data a few days ago. The data shows that on January 1, 1990, 2,784 babies were born in Shanghai. Ten years later, on January 1, 2000, 1,148 babies were born in Shanghai. In 2010, the number became 380. , 2020 only 156 people, the decline in the birth rate is shocking. The three most critical reasons are: I don't want to give birth, I can't afford it, I can't give birth! The decline of the global population will bring a series of economic and social problems, among which the demand for ZrO2 will also be affected.
What is zirconia toughened alumina ZTA?
Zirconia toughened alumina is a kind of ceramic material composed of alumina and zirconia. It is a kind of composite ceramic material containing zirconia particles in alumina matrix. It is also known as ZTA.
Zirconia alumina (or zirconia toughened alumina) is a kind of composite ceramic called AZ composite, which is composed of zirconia and alumina. AZ composites are known for their mechanical properties and are commonly used in structural applications, as cutting tools and many medical applications. In addition, AZ composites have high strength, fracture toughness, elasticity, hardness and wear resistance. In particular, zirconia toughened alumina (ZTA) has several important properties.
ZTA mechanical properties
Compared with alumina, the mechanical robustness of ZTA is attributed to the displacement phase transition of metastable tetragonal zirconia grains under stress. The stress concentration at the crack tip can lead to the transformation of zirconia from tetragonal to monoclinic crystal structure, accompanied by the volume expansion of zirconia. This volume expansion effectively promotes crack propagation and leads to higher toughness and strength of zirconia toughened alumina samples with a zirconia content of 10-20%. An increase of 20-30% in strength usually meets the design standards, and the cost is much lower, according to the percentage of zirconium, the properties of this ceramic can be operated as needed. Zirconia toughened alumina is generally considered to be an intermediary between alumina and zirconium, and as such a price. This makes the price range of ZTA much lower than that of other similar materials. The increase in strength of composites is achieved through a process called stress-induced transformation toughening. This process will produce internal strain and lead to cracks in the structure of zirconium. Due to the existence of cracks, zirconium particles can switch phases between alumina particles and move more freely. In the same amount of alumina particles, zirconia particles will increase, resulting in an increase in strength.
What is zirconia toughened alumina ZTA used for?
Zirconia toughened alumina has been widely used, including valve seal, casing, pump assembly, joint implantation, wire connection capillaries, tool blades and other ZTA has a variety of properties, which is of great significance in a series of applications. In the medical industry, ZTA, as a ceramic, can be used for joint replacement and rehabilitation. The high wear resistance of ZTA contributes to the manufacture of high performance implants. Because of its high strength and corrosion resistance, ZTA enables materials to withstand heavy loads without succumbing to degradation, and ZTA has many uses in load-bearing applications. The toughness of ZTA also means that it has many uses in cutting tools. ZTA and other alumina are often used in metal cutting applications. Some engine components, laboratory appliances, industrial crucibles, and refractory tubes can be manufactured using ZTA. In addition, some abrasive applications, such as sandblasting, can also be manufactured using ZTA.

Commodities such as crude oil, wheat, cotton, and nickel have rallied since Russia's "special military operations" began in late February. On the last trading day of this quarter, commodities were on track for their biggest gain since 1990. For this reason, it is expected that the price of the ZrO2 will continue to increase.
