АЦЕТАТ НЕОДИМА

Description

Neodymium acetate (hydrate) is a water-soluble salt of acetic acid and neodymium(III) in the form of crystalline hydrate (neodymium acetate monohydrate). Like other water-soluble neodymium salts, it serves as a convenient source of Nd3+ ions for further synthesis.

Scope of application

Hydrated neodymium acetates are used as high-purity precursors in the production of neodymium-containing catalysts, optical glass, magnetic materials and other chemical reagents; their solubility in water facilitates their use in liquid-phase methods for the synthesis of nanoscale materials and doping glass for coloring in shades from violet to wine red and warm gray. The hydrate form differs from anhydrous neodymium acetate in its higher dissolution rate and ease of dosing in aqueous technological solutions, therefore it is preferable where rapid and complete dissolution of the reagent without preheating is required.

• precursor to neodymium-containing catalysts
• raw materials for optical glass and magnetic materials
• glass and crystal dye
• reagent for liquid-phase synthesis of nano-sized neodymium-containing materials and functional coatings

Storage and transportation

Store in a tightly closed container, in a dry place, away from moisture - the substance is hygroscopic and highly soluble in water. The noticeable vapor pressure (13.9 mmHg at 25 °C) requires a ventilated room during long-term storage, since part of the moisture of the crystalline hydrate gradually evaporates even at room temperature. When working, wear gloves, safety glasses, avoid inhaling dust and getting the solution on the skin and mucous membranes. This hydrate differs from the anhydrous form of the compound (CAS 6192-13-8) in its higher dissolution rate, which determines its choice where the technological process does not allow preheating of the reagent. Both compounds - hydrate and anhydrous salt - serve as interchangeable sources of Nd3+ ions, and the specific form is selected based on the requirements of a specific technological regulation for the dissolution rate and the permissible residual moisture of the reagent for a specific technical process of material synthesis.
