Neodymium oxide is stored in the manufacturer's packaging in dry closed warehouses at a temperature not lower than +10 ° C and a relative humidity of not more than 70%. Guaranteed shelf life of cerium carbonate – 5 years. LANTHANUM OXIDE
These technical conditions apply to the lanthanum oxide used for the production of catalysts, additional alloying, glass and special-purpose ceramics as well as for research in various fields of science and technology.
To characterize the manufactured grades of material are introduced designations: grades «Г», «Д», «Ж» and «Л». Сonditional content of lanthanum oxide in grades, %, not less:
Grade-«Г»-99,9997; Grade-«Д»-99,999; grade-«Ж»-99,9896; grade-«Л»-99,8958.
Examples of product records for ordering and documentation: Lanthanum oxide grade «Г». TC 20.13.65-005-92697718-2018.
By chemical indicators, lanthanum oxide must comply with the requirements given in Table.
