Yttrium oxide is a colorless or white solid powder with the chemical formula Y2O3. It has stable chemical properties and is insoluble in water and large particles at room temperature
Most inorganic acids, but easily soluble in strong alkaline solutions. It has excellent physical and chemical properties such as high thermal stability, radiation resistance, rezistență la uzură, and corrosion resistance. În plus, the density of yttrium oxide is approximately 5.0-5.15 g/cm ³， And it has a large specific surface area.
The role of yttrium oxide is very extensive, specifically manifested in the following aspects:
1. Câmp electronic: Yttrium oxide is an indispensable component in electronic component packaging technology, which can improve the reliability and product performance of components
Can. It is mainly used for chip packaging, MIM resistors, resistor cable packaging, positioning electrode packaging, etc., by providing physical isolation and connection,
Ensuring the stability and reliability of the circuit board.
2. Material field: Ultrafine yttrium oxide plays an important role in the production of laser materials, superconducting materials, and other functional materials. Meanwhile,
It is also used to manufacture composite oxides such as single crystals, yttrium aluminum neodymium garnet, and yttrium iron garnet, which are used in magnetic materials for microwave applications
It has the characteristic of good high-frequency performance in military communication engineering.
3. Ceramics and Optics: Yttrium oxide is an important raw material for manufacturing ceramic materials such as ceramic capacitors, catalyst carriers, and artificial alumina,
În același timp, it can also serve as an additive for ceramic materials. In the field of optics, yttrium oxide is used to manufacture high-quality optical glass, improving
The performance of optical devices.
4. Medical field: Yttrium oxide is widely used in medical devices, such as orthopedic medical devices, clinical medical instruments, and artificial joints.
Especially yttrium oxide artificial joints are widely recognized for their long service life and low susceptibility to damage.
