Cerium(III) sulphate Ce₂(SO₄)₃, also known as Cerous Sulfate or Dicerium Trisulfate, is a highly versatile Rare Earth Sulfate compound. It is typically supplied in its anhydrous form (CAS 13454-94-9) as a white to off-white crystalline powder, or most commonly as the octahydrate Cez (SO4)3 • 8H20. Cerous Sulfate valued as a high-purity Water-Soluble (RRe) Rare Earth source, making it an essential Cerium Reagent in liquid-phase reactions. A unique and critical Scientific property is its Inverse Solubility Phenomenon: unlike most salts, its solubility in water decreases dramatically as the temperature increases, which is leveraged in industrial separation processes. Primary B2B roles include serving as an industrial catalyst precursor, a key intermediate in the synthesis of other Cerium compounds, and a specialised reagent in Analytical Chemistry. We are a leading & trusted Cerium sulphate supplier worldwide, offering Cerium sulfate forms and various other RRes that meet quality and safety standards, with reliable lead times and global supply capability.

Acts as a Water-Soluble Rare Earth component in textile processing for dyeing and printing textiles and for waterproofing and mildew-proofing fabrics. Production of infrared filters and photosensitive glass
Manufacture specialized high surface-area CeO2 and mixed-oxide catalysts. Functions as a key Cerium Catalyst Precursor in applications like fluid catalytic cracking (FCC) additives and in automotive exhaust catalyst systems
Essential Chemical Intermediate for synthesising other Ce³⁺ compounds. In Analytical Chemistry, the related Cerium(IV) Sulfate is one of the strongest Oxidation-Reduction Titrant agents, for which Ce(III) Sulfate serves as a precursor or reference standard
Used as a reference standard in Spectroscopy and as a high-purity Cerium Salt Raw Material in various research applications requiring a precise, soluble rare earth source
Few inorganic salts that exhibits an Inverse Solubility Phenomenon or negative temperature coefficient of solubility-much higher in cold water (e.g., 10.1g/100mL at 0°C) than in hot water. This unique trait is leveraged in B2B manufacturing for the efficient purification and selective crystallisation of the Ce(III) species.
It is in reduced form, crucial precursor for producing Cerium(IV) Sulfate. The Ce(IV) species is a powerful, stable Oxidation-Reduction Titrant widely used in Analytical Chemistry for standardising solutions and measuring the concentration of various reducing agents (cerimetry).
Octahydrate (Ce₂ (SO₄)₃ • 8H₂O) - preferred commercial product for applications requiring aqueous solutions (like textiles and wet chemical synthesis) because it is less hygroscopic and easier to weigh accurately. Anhydrous form – specialised high-temperature processes or moisture-sensitive Chemical Intermediate syntheses.
Excellent Cerium Catalyst Precursor because the sulfate anion decomposes cleanly upon heating, leaving behind a highly reactive Cerium Oxide CeO2 structure. The resulting CeO2 is integral to technologies like fluid catalytic cracking (FCC) and three-way catalysts due to its superior Oxygen Storage Capacity (OSC) performance.
