Rubidium hydroxide hydrate is a crucial inorganic rubidium compound with the chemical formula RbOH·xH₂O. It exists as a white crystalline powder at room temperature. As one of the strongest known alkalis, its basicity surpasses that of potassium hydroxide. This product exhibits extremely high hygroscopicity, dissolves readily in water with significant heat release. As a key source of rubidium and a potent alkali, it serves as a core raw material for preparing various rubidium compounds and applications in high-end technological fields.
We offer RbOH hydrate powder with varying water content (x-value), available in purities of 99% (metals basis) and above. Flexible packaging options range from gram to kilogram quantities. Contact us for quotations or sample requests.

Q1: What do “xH₂O” and “hydrate content” in the product specification mean?
A1: “xH₂O” indicates the product is a crystal formed by rhodium hydroxide combining with water molecules, where x represents the number of water molecules (typically 1/2, 1, 2, or 4). Hydrate content (e.g., 15-20% H₂O) denotes the mass percentage of crystalline water in the product, which affects the actual RbOH equivalent and must be considered during precise measurement.
Q2: What are the corrosivity and toxicity of rubidium hydroxide hydrate? What precautions should be taken during handling?
A2: This product is highly corrosive and can cause severe burns to skin and eyes. It is classified as toxic, with an oral LD50 of 586 mg/kg in rats. Handling requires protective clothing, gloves, and goggles in a well-ventilated area. Contact with acids, metals, and ammonium salts is strictly prohibited.
Q3: Are there special storage and transportation requirements for this product?
A3: Due to its extreme hygroscopicity and reactivity with atmospheric carbon dioxide, the product must be stored in a cool, dry place under strict seal. During transportation, it must be handled as a corrosive hazardous material, ensuring packaging integrity to prevent moisture ingress and damage.
Q4: Can extremely small quantities be ordered for experimental R&D purposes?
A4: Yes. We understand R&D needs and offer small packaging sizes. We also support full-range supply from R&D to production to meet customer requirements at different stages.
