3 Requirements

3.1 Categories Products are solid and liquid forms. The solid product is divided into three grades according to chemical composition, ReCl3-45A, ReCl3-45B, ReCl3- 45C; liquid products according to the chemical composition is also divided into three grades. ReCl3-26A, ReCl3-26B, ReCl3-26C, product grades representation shall comply Co GB/T 17803 requirements. 3.2 Character Grade Description and examples According to GB/T 17803, mixed rare earth chloride grade from product suppliers, specific letters and Arabic numerals, divided into two levels, Wherein the first level is represented by the product of the formula; the second level indicates that the product level (specifications). For solid products, to a second level Of rare earth rare earth chloride representation of rare earth oxide, the mass fraction rounding method adopted after rounding takes first two digits indicate that when quality The amount of the fraction is a single digit, then use rounded rounded rounded, then the numbers before the "0" to make up two digits; for liquid Body products, the second level of rare earth chloride concentration of rare earth to represent. For TREO (mass fraction) or the same concentration, but other ingredients (Including impurities) content requirements of different products, can be added successively in the last group grades uppercase letters A, B, C, D, said to show the difference. In between the first level and the second level with a "-" separated. ×× The first level indicates that the product name ×× The second level indicates that the product level (specifications) ......
