Summary This standard specifies the use of X-ray diffraction method to determine the content of silica crystal phase in hydrogenation catalysts and their carriers. This standard is applicable to the determination of the ��-silica crystal phase content in hydrogenation catalysts and their carriers in the range of 0.33% to 10.22% (mass fraction). The determination of low-temperature cristobalite crystal phase content in hydrogenation catalysts and their carriers can also refer to this standard, but this standard does not examine its precision.
