Foreword
This standard replaces GB/T 16482-1996 "yttrium oxide phosphor grade."
This standard compared with GB/T 16482-1996, the main changes are as follows.
--- Cancel the original grade (Y, Eu) 2O3, with particle size specification is divided into three grades;
--- Adjustment yttrium europium oxide content in the range;
--- Value adjustment center particle size (D [V, 50]) range.
