YB/T 5156-2016 in English

This standard outlines a method for determining the silicon content in high-purity graphite products using the silicomolybdenum blue spectrophotometric method. It provides detailed procedures for sample preparation, reagent selection, and measurement techniques. The method involves the reaction of silicon with molybdenum to form a colored complex, which is then measured using spectrophotometry. The standard specifies the required equipment, calibration procedures, and conditions for accurate measurement. It also includes information on quality control measures and data interpretation. This document is intended for use by professionals in the field of materials testing and analysis, ensuring consistency and reliability in the determination of silicon levels in high-purity graphite products. The procedures described are applicable to a wide range of samples and are designed to be reproducible under various testing environments.
