GB/T 5124.3-1985 《Methods for chemical analysisof hardmetals--The potentiometric method for the determination of cobalt content》 Related products

GB/T 5124.3-1985 for cemented carbide, specifies the method of determining the amount of cobalt by the potential Titrimetric method. This standard is suitable for all kinds of cemented carbide samples, and describes the principle of using potential changes to indicate the end point of titration to determine the amount of cobalt. Clarify the required equipment, such as Potentiometric titrator, and related reagents. Detail the processing steps of cemented carbide samples, including dissolve, remove interfering elements, etc. Then introduce the titration operation process, covering titrant addition, potential monitoring and result calculation. With this standard, the cobalt content in cemented carbide can be accurately determined, providing key data support for cemented carbide mass control and performance evaluation.
