Introduction
Overview of Anhydrous Lanthanum Chloride Standards
GB/T 31964-2015 "Anhydrous Lanthanum Chloride" is a national standard formulated by China for anhydrous lanthanum chloride products. It mainly stipulates the product's technical requirements, test methods, inspection rules, and requirements for marking, packaging, transportation and storage.
Comparison of standard frameworks
| Dimension | Scope | Content description |
|---|---|---|
| Product classification | Grade classification | L a C l 3( A nhydrous ) - 4 N, La C l 3( A nhydrous ) - 3 N, La C l 3( A nhydrous ) - 2 N 5 |
| Chemical composition | Mass fraction requirement | REO not less than 66.30%; La 2O 3 / REO not less than 99.99%; Cl- not less than 43.24% |
| Test method | Test standard reference | GB/T 606 (water content determination), GB/T 3050 (chloride content determination), etc. |
Implementation suggestions and precautions
1. Chemical composition control:Focus on the total amount of rare earth oxides, relative purity of lanthanum oxides and impurity content to ensure compliance with the provisions of Table 1.
2. Appearance quality requirements:The product should be white powder or granules without visible inclusions. The packaging seal should be checked regularly to avoid moisture.
3. Sample sampling method:Follow the provisions of GB/T 16484.16 to ensure that the sample is representative. The number of arbitration samples shall be implemented in accordance with Table 2.
