Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
This standard replaces GB/T 3503-2006 "yttria."
This standard compared with GB/T 3503-2006, the main technical changes are as follows.
--- Adds character designation (see Chapter 3);
--- Increased grades 171,055, assessment of all rare earth impurities and some non-rare earth impurity element (see Table 1);
--- 171 050 modified grades of all Rare Earths Elements assessment indicators in addition to dysprosium, while modifying the non-rare earth impurities of iron, calcium,
Copper, lead, nickel assessment indicators (see Table 1);
--- 171 045 modified grades of all Rare Earths Elements assessment indicators in addition to europium, terbium, dysprosium, holmium, erbium and thulium, and modify the
Non-rare earth impurities of iron, copper, lead, nickel and chlorine assessment indicators (see Table 1);
--- Modified grades of neodymium, samarium, europium, gadolinium, terbium, ytterbium and lutetium assessment indicators 171,040, while modifying the non-rare earth impurities of iron, copper, lead,
Nickel and chlorine assessment indicators (see Table 1);
--- Modify the physical properties of the product scope of examination (see Table 1);
--- Deleted grades 171 020 (see Table 1, 2006 edition).
