Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard is proposed and managed by the National Semiconductor Equipment and Materials Standardization Technical Committee (SAC/TC203). This standard was drafted. National Silicon Materials Deep Processing Product Quality Supervision and Inspection Center, Jiangsu Lianrui New Materials Co., Ltd., Henkel Warwick Electronics Co., Ltd. The main drafters of this standard. Feng Lijuan, Li Bing, Chen Jin, Xia Yongsheng, Cao Jiakai, Lu Fufa, Qi Jianjun, Wang Songxian. Α-state crystal in spherical silica fine powder for electronic packaging Test method for silica content XRD method

1 Scope

This standard specifies the XRD test method for the content of α-state crystalline silica in spherical silica micropowder for electronic packaging. This standard is applicable to the detection of α-state crystalline silica content in spherical silica micropowder for electronic packaging, other amorphous silica. The detection of the content can also be carried out with reference to this standard. Α-state crystalline silica content test range of 0.5% or less semi-quantitative analysis, 0.5% to 5% Quantitative analysis.
