Global Gadolinium Oxysulfide Market Strategic Research Report

Scope of the Report

The global Gadolinium Oxysulfide market size is predicted to grow from US$ 55.96 million in 2025 to US$ 79.57 million in 2032; it is expected to grow at a CAGR of 5.5% from 2026 to 2032.

Gadolinium oxysulfide, with the chemical formula Gd₂O₂S, is a rare-earth oxysulfide functional powder material. Industrial products mainly include undoped gadolinium oxysulfide powder and doped gadolinium oxysulfide phosphor powders activated by rare-earth ions such as terbium, praseodymium and europium, including Gd₂O₂S:Tb, Gd₂O₂S:Pr and Gd₂O₂S:Eu. These materials offer strong X-ray absorption, stable luminescent performance and good chemical stability, and are primarily used as X-ray phosphors, scintillator powders, ceramic-grade raw powders for scintillator ceramics and functional materials for radiation imaging. In 2025, the global gadolinium oxysulfide sales is estimated at about 520 tons, with an average selling price of around USD 110 per kg.

The gadolinium oxysulfide powder value chain starts with rare-earth oxides such as gadolinium oxide, terbium oxide, praseodymium oxide and europium oxide, as well as sulfur sources, fluxes, reducing or protective atmospheres, high-purity chemical auxiliaries and powder-processing equipment.

The growth of the gadolinium oxysulfide powder market is primarily driven by sustained demand for stable rare-earth scintillation powders in medical X-ray imaging, industrial non-destructive testing, security inspection and upstream materials for CT detectors. Doped powders such as Gd₂O₂S:Tb and Gd₂O₂S:Pr offer strong X-ray absorption, good luminescent efficiency, mature synthesis processes and relatively stable material costs, making them suitable for X-ray phosphors, scintillator powders and ceramic-grade raw powders for scintillator ceramics. Demand is supported by medical imaging equipment upgrades, automation in industrial inspection, airport and public-security screening upgrades, and the need for low-afterglow, high-brightness and particle-size-controlled powders in high-end CT and radiation imaging applications. At the same time, stricter requirements from downstream scintillator ceramics and high-performance imaging materials for powder purity, particle-size distribution, dopant uniformity and batch-to-batch consistency are pushing gadolinium oxysulfide powders toward high-purity, low-afterglow, ceramic-grade and customized functional powder products.
