Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces XB/T 105-1995 "Ytrite Concentrate".
Compared with XB/T 105-1995, the main technical changes of this standard are as follows.
---Adjust the product brand to a digital brand;
---Increase the indicators for measuring the total amount of REO ThO2 and ThO2 to reduce the mixing of monazite ore;
--- Modify the content of Y2O3 to "Y2O3/REO not less than";
---The content of TiO2 has been lowered to reduce the mixing of ilmenite.
This standard is under the jurisdiction of the National Rare Earth Standardization Technical Committee (SAC/TC229).
This standard was drafted. Yixing Xinweilicheng Rare Earth Co., Ltd., Hunan Rare Earth Metal Materials Research Institute.
The main drafters of this standard. Yu Zhichun, Zou Bin, Weng Guoqing, Liu Rongli.
The previous versions of the standard replaced by this standard are as follows.
---YB/T 838-1987;
---XB/T 105-1995.
