ReO≥86.5% Praseodymium Fluoride (PrF₃) CAS 13709-21-6 for Rare Earth Metal Production, Optical Materials, and Functional Ceramic Applications

1. Product Overview

Praseodymium Fluoride (PrF₃) is an important rare earth fluoride material and a key raw material for the production of praseodymium metal and praseodymium-based functional materials.

Praseodymium fluoride exhibits good chemical stability and high rare earth element utilization value. It is mainly used in rare earth metal production, optical materials, ceramic pigments, functional materials, and specialty alloy applications.

According to the rare earth fluoride product indicator system, praseodymium fluoride primarily focuses on ReO (total rare earth oxide content), F content, oxygen content, and loss on ignition indicators. Typical specifications are ReO≥86.5%, F≥29%, O≤2000 ppm, and loss on ignition ≤3000 ppm.

For the Russian market, this product is mainly targeted at rare earth smelting enterprises, optical material companies, functional ceramic enterprises, research institutions, and rare earth raw material traders.

7. Frequently Asked Questions (FAQ)

Q: Which industries primarily use praseodymium fluoride?

A: It is mainly used in rare earth metal production, optical glass, functional ceramics, specialty pigments, and rare earth alloy materials.

Q: What does ReO≥86.5% represent?

A: ReO represents the total rare earth oxide content and is an important indicator for evaluating the effective rare earth component of rare earth fluorides. Higher ReO typically indicates a higher effective rare earth content.

Q: What is the difference between praseodymium fluoride and neodymium fluoride?

A: Praseodymium fluoride corresponds to single praseodymium element applications, mainly used in praseodymium-based materials, optics, and ceramics; neodymium fluoride primarily serves neodymium-based materials and the permanent magnet material industry chain.

Q: Why is it necessary to control oxygen content and loss on ignition in praseodymium fluoride?

A: Oxygen content and loss on ignition reflect the levels of oxides, moisture, and volatile impurities in the product, which have significant impacts on rare earth metal production and high-performance material applications.

Q: What documents are required for purchasing praseodymium fluoride in Russia?

A: Typically, COA, TDS, SDS, certificate of origin, and packaging information are required.
