Yttrium oxide granules are white inorganic compound granules with a melting point of 2410°C. They are insoluble in water but soluble in acids, and exhibit excellent thermal and chemical stability, remaining stable without decomposition or reaction in high-temperature environments. They also offer good dielectric properties, strong electrical insulation, and relatively low thermal conductivity, making them an ideal material for high-temperature insulation applications.

Yttrium oxide granules is packed in sealed, moisture-proof containers, typically with double-layer plastic liners and durable outer drums or cartons to prevent moisture absorption and contamination. Packaging should avoid impurities and include clear labels for product identification and traceability.
For storage, yttrium oxide granules should be kept in a cool, dry, and well-ventilated place, away from moisture, acids, and corrosive substances. Containers should remain tightly sealed to prevent agglomeration, and exposure to extreme temperatures or mechanical stress should be avoided to maintain stable performance.
Q1: What is yttrium oxide granules？
A: Yttrium oxide, with the chemical formula Y₂O₃, is an important rare earth oxide. It appears as a white to pale yellow powder, insoluble in water and alkalis, but soluble in acids. It possesses high chemical stability and excellent optical and electrical properties.
As a key rare earth functional material, it plays a central role in modern industrial fields such as high-end manufacturing, new materials, electronics, and new energy.
Q2: What is yttrium oxide used for?
A: Yttrium oxide (Y₂O₃) possesses high-temperature stability and is an important ceramic material widely used in red phosphors (for color TVs and fluorescent lamps), optical glass, oxygen sensors, ceramics, high-temperature superconducting materials, and catalysts.
Q3: Is yttrium oxide granules toxic?
A: While Y₂O₃ itself has low toxicity, safety precautions are still necessary during handling and use.
For example, Y₂O₃ in powder form may generate dust, and long-term inhalation of this dust can irritate the respiratory system. Therefore, when handling Y₂O₃, appropriate protective measures are recommended, such as wearing dust masks, gloves, and goggles, to reduce dust inhalation and skin contact.
