ReO≥77% Lanthanum Fluoride (LaF₃) CAS 13709-38-1 for Optical Materials, Crystal Materials, and Specialty Functional Material Applications

1. Product Overview

Lanthanum Fluoride (LaF₃) is an important light rare earth fluoride material and a key raw material for the production of lanthanum-based functional materials and specialty optical materials.

Lanthanum fluoride exhibits good optical transmittance, chemical stability, and radiation resistance. It is mainly used in optical crystals, laser materials, optical fiber glass, specialty ceramics, and functional material applications.

According to the rare earth fluoride product indicator system, lanthanum fluoride primarily focuses on ReO (total rare earth oxide content), F content, oxygen content, and loss on ignition indicators. Typical specifications are ReO≥77%, F≥39%, O≤1000 ppm, and loss on ignition ≤1500 ppm.

For the Russian market, this product is mainly targeted at optical material enterprises, crystal material companies, optical fiber manufacturers, rare earth material enterprises, and traders of high-purity inorganic materials.

7. Frequently Asked Questions (FAQ)

Q: Which industries primarily use lanthanum fluoride?

A: It is mainly used in optical crystals, optical fiber glass, laser materials, specialty ceramics, and functional material applications.

Q: What does ReO≥77% represent?

A: ReO represents the total rare earth oxide content and is an important indicator for evaluating the effective rare earth content of rare earth fluorides.

Q: What is the difference between lanthanum fluoride and cerium fluoride?

A: Lanthanum fluoride is mainly used in optical crystals, optical fiber glass, and lanthanum-based functional materials; cerium fluoride is more commonly used in cerium-based materials, polishing materials, and glass additive fields.

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

A: Low oxygen and low loss on ignition help improve product purity and reduce the impact of impurities on optical performance and material stability.

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

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