In May 2025, China's rare earth prices showed an initial increase followed by a slight decline. The average price of praseodymium oxide was 445,000 yuan/ton, decreased by 1.18% month-on-month; praseodymium-neodymium oxide averaged 428,684 yuan/ton, increased by 0.65% month-on-month; praseodymium-neodymium metal averaged 527,053 yuan/ton, increased by 0.52% month-on-month; terbium oxide averaged 7,095 yuan/kg, increased by 2.90% month-on-month; and dysprosium-iron alloy averaged 1,598,947 yuan/ton, decreased by 1.55% month-on-month.

Tungsten flux needs to be packaged in moisture-proof and sealed packaging. The supply and demand parties shall negotiate and decide whether to package in bags, bottles, cans or barrels, etc. The packaging label name and specifications and other information. During storage and transportation, high temperature, fire source and strong oxidants should be avoided, and ventilation and dryness should be maintained. Handle with care to prevent leakage.

In May 2025, China’s molybdenum price trend was initially stable before experiencing a significant surge. In terms of average prices, molybdenum concentrate averaged 3,583 yuan/ton-degree, increased by 6.83% month-on-month; ferromolybdenum averaged 233,737 yuan/ton, increased by 7.38% month-on-month; molybdenum oxide averaged 3,667 yuan/ton-degree, increased by 5.83% month-on-month; ammonium heptamolybdate averaged 226,947 yuan/ton, increased by 4.15% month-on-month; and molybdenum powder averaged 425 yuan/kg, increased by 5.20% month-on-month.

Tungsten flux, also known as tungsten particles, is a granular substance made of high-purity tungsten metal (usually purity ≥99.95%). It has a silver-gray or light-gray polyhedral structure and has the characteristics of high density, high melting point, high hardness, corrosion resistance, strong conductivity and small thermal expansion coefficient. It is generally used as a flux in carbon-sulfur analyzers to analyze the carbon and sulfur content in steel, alloys, ceramics, minerals and other inorganic substances. Tungsten flux can promote the melting of the test sample through oxidation combustion and heat release, and it is not easy to splash, which is conducive to stabilizing the carbon-sulfur analysis results.
