Products Description

Lanthanum oxide powder is an inorganic compound with the chemical formula La ₂ O æ, which appears as a white powder. It is soluble in acids, ethanol, and ammonium chloride, but insoluble in water and ketones. When exposed to air, it easily absorbs carbon dioxide and water, gradually turning into lanthanum carbonate. In addition, it also has a high melting point (2315 ℃) and high density (6.51 g/cm) ³) Equal physical properties.

FAQ

Q: How to prepare it?

A: There are various methods for preparing it, including solid-phase reaction, liquid-phase reaction, and gas-phase reaction. Among them, solid-phase reaction method is one of the most commonly used methods, which usually involves mixing lanthanum compounds with oxidants and calcining them at high temperatures to obtain it.

Q: How does the purity of it affect its performance?

A: The purity of it has a significant impact on its performance. High purity it has better optical and electrical properties, which can meet the needs of high-end applications. Therefore, it is necessary to strictly control the purity of the raw materials and reaction conditions during the preparation process to obtain high-purity it.

Q: What are the storage and usage precautions for it?

A: it should be stored in a dry, ventilated, and cool place to avoid contact with chemicals such as acids and alkalis. During use, protective goggles and gloves should be worn to avoid inhalation or contact with skin and eyes. In addition, due to the high water absorption of it, attention should be paid to moisture prevention during use.
