1. Product Overview

Dysprosium Fluoride (DyF₃) is an important heavy rare earth fluoride material and a key raw material for the production of dysprosium metal and dysprosium-based functional materials.

Dysprosium fluoride exhibits good chemical stability and high rare earth element utilization value. It is mainly used in rare earth metal production, high-performance magnetic materials, nuclear industry materials, optical materials, and specialty functional material applications.

According to the rare earth fluoride product indicator system, dysprosium fluoride primarily focuses on ReO (total rare earth oxide content), F content, oxygen content, and loss on ignition indicators. Typical specifications are ReO≥84%, F≥26%, O≤2000 ppm, and loss on ignition ≤3000 ppm.

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