Yttrium oxide, or yttria, is a rare earth oxide with multi-application potential across various industries. Applications of yttrium oxide in magnetic materials, ceramic additives, phosphors, film capacitors, and special refractory materials are discussed here. If one reads through the properties of yttrium oxide, it is easy to realize the importance of yttrium oxide in these forefront industries.
Yttrium oxide is also used extensively as an additive in magnetic materials such as magnetic recording media and magnetic alloys. Yttrium oxide addition to these materials greatly enhances their magnetic properties, i.e., magnetic coercivity and remanence. Besides this, yttrium oxide, when utilized as a stabilizer, also enhances the chemical and thermal stability of these materials.
Yttrium oxide finds usage as an additive in various ceramic applications, such as ceramic coatings, filters, and capacitors, to improve their mechanical strength, hardness, and toughness. It can also be used for improving the thermal and chemical stability of ceramics for longer life and better performance.
Yttrium oxide is also commonly applied as a phosphor in many products, including fluorescent lamps, cathode ray tubes, and plasma displays. As a phosphor dopant, its application results in excellent improvement in luminescent features, including brightness and color purity enhancement. Further, as a host material for phosphors, yttrium oxide is utilized to enhance the final product's performance and lifetime.
Yttrium oxide is widely used as a dielectric in film capacitors for many electronic devices such as smartphones, computers, and televisions. Yttrium oxide incorporated into the dielectric material enhances the insulation characteristic of the material, leading to higher capacitance and hence miniaturization of the capacitor. Yttrium oxide can also be utilized to enhance the thermal and chemical stability of dielectric materials, enhancing the lifetime and credibility of the corresponding capacitor.
Yttrium oxide is used in specialized refractory materials such as high-temperature coatings, crucibles, and electrodes because of its melting point and heat conductivity. Yttrium oxide also adds chemical resistance to refractory materials, which prolongs their life and efficiency.
