In the fields of rare‑earth fine chemicals, new‑energy materials, environmental‑friendly water treatment and petrochemicals, the stability of high‑quality raw materials directly determines the finished‑product quality and process efficiency. As a core rare‑earth chloride feedstock, praseodymium chloride serves as a vital upstream material for praseodymium‑based compound synthesis, industrial catalysis, water remediation and the manufacture of new‑energy magnetic materials. Drawing on a mature automated production system and strict quality‑control standards, Sichuan Wonaixi New Materials Technology Co., Ltd. has long been engaged in the R&D and production of rare‑earth raw materials. We supply industrial‑grade praseodymium chloride with complete specifications, stable indicators and wide adaptability, delivering standardized raw‑material supply solutions for clients across multiple industries.

Wonaixi praseodymium chloride is hexahydrate praseodymium chloride (PrCl₃·6H₂O) with the standard CAS No. 10025‑90‑8. The finished product appears as uniform, translucent green crystals with stable physicochemical properties, making it a highly versatile basic rare‑earth feedstock for industrial applications. Replacing the traditional extensive‑production mode, our company adopts a high‑grade raw‑material screening system and automated production lines together with standardized batch management. Closed‑loop control runs through the whole workflow: incoming‑raw‑material inspection, manufacturing, impurity testing and finished‑product release. This ensures every batch of praseodymium chloride meets purity requirements with well‑controlled impurities, satisfying the demands of large‑scale industrial production and precision laboratory‑scale experiments.

For rigorous quality management, Wonaixi provides two mainstream grades of praseodymium chloride: PL‑2.5N and PL‑3N. The total rare‑earth oxide (TREO) content remains stably ≥ 47 %, while the high‑purity grade reaches up to 99.9 % praseodymium‑oxide content in TREO. Multiple impurity indicators are tightly regulated. Rare‑earth impurities including lanthanum, cerium and neodymium, together with non‑rare‑earth impurities such as calcium, iron, sodium, potassium, lead and aluminum, are maintained at low industry‑competitive levels. Key parameters including sulfate content and turbidity fully comply with relevant standards. The product is well‑suited for high‑end fine‑chemical and new‑energy‑material production requiring strict raw‑material purity, and effectively reduces adverse impacts of impurities on end‑product performance.

Excellent physicochemical properties grant Wonaixi praseodymium chloride strong industrial compatibility. It features outstanding water solubility and acid solubility, dissolving rapidly in water and various strong‑acid solvents to form homogeneous solutions without residual sediment. It is compatible with numerous industrial processes such as wet‑phase synthesis, catalytic reactions and phosphate precipitation. Furthermore, standardized manufacturing ensures superior batch‑to‑batch consistency, alleviating common problems of conventional chemical feedstocks such as large performance fluctuations. It helps manufacturers achieve stable production and improved process precision.

Benefiting from reliable performance, Wonaixi praseodymium chloride is widely deployed across key industrial sectors to drive efficiency‑upgrading throughout industrial chains. In petrochemicals, it functions as a dedicated catalyst for petroleum cracking, optimizing cracking workflows, boosting fuel‑production efficiency and improving end‑product quality. In environmental water‑treatment projects, it acts as an efficient phosphorus‑removal reagent that rapidly precipitates phosphate from water bodies and mitigates eutrophication in aquaculture ponds, landscape waters and small‑scale sewage systems with stable treatment outcomes. Within the new‑energy sector, praseodymium chloride is an essential precursor for producing metallic praseodymium, which is further processed into rare‑earth permanent‑magnets and hydrogen‑storage alloys widely used in electric‑vehicle, wind‑power generation and energy‑storage equipment. In fine‑chemical synthesis, it serves as an intermediate for manufacturing diverse praseodymium salts, ceramic colorants and innovative magnetic materials, occupying an important position in the rare‑earth new‑material industrial chain.

Apart from premium product quality, Wonaixi New Materials provides comprehensive procurement‑related guarantees via well‑developed supply and packaging systems. To meet bulk industrial‑purchase requirements, finished goods are protected by a three‑layer packaging solution: vacuum sealing, cushion‑shock protection and steel‑drum containment, which effectively prevents moisture damage, breakage and contamination during transit. Available packages include standard 50 kg steel drums and large‑capacity 1000 kg bulk bags. Palletized shipment enables high‑density, neatly‑arranged cargo loading adaptable to sea freight, air freight and other transport modes. We can deliver consistent long‑term supplies for domestic and international customers.
