Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
Instead of the standard YS/T 322-1994 "metallurgical titania technical conditions."
This standard YS/T 322-1994 compared to the main changes are as follows.
--- Chemical composition of the new addition of Al2O3, Cr2O3, CaO requirements, in addition to the original elemental C outside all changed oxide;
--- Rating cancel, leaving only the grades;
--- Provisions on ignition and detection of particle size;
--- Of standard signs, packaging, transportation, storage explicitly;
--- Supplementary order form requirements.
This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) and focal points.
This standard was drafted. Yunnan Xinli Nonferrous Metal Co., Ltd., Baoji Titanium Group Co., Ltd. Dalian Rong Gaudet kinds of materials.
