《GB/T 43131-2023人造金刚石磁化率测定方法》由TC139（全国磨料磨具标准化技术委员会）归口，TC139SC3（全国磨料磨具标准化技术委员会超硬材料及制品分会）执行，主管部门为中国机械工业联合会。
Introduction
1. Background and significance of standard formulation
Magnetic susceptibility is an important parameter for measuring the magnetic properties of materials and is widely used in scientific research and industry. With the widespread application of artificial diamonds in precision machining, semiconductors and other industries, the accurate determination of their magnetic susceptibility is particularly important. This standard is based on the existing technical foundation and combines industry needs to standardize the determination method of the magnetic susceptibility of artificial diamonds to ensure the accuracy and consistency of the data.
2. Comparative analysis of standard frameworks
| Standard dimensions | GB/T 43131—2023 | International reference standards | Main differences |
|---|---|---|---|
| Scope of application | Determination of magnetic susceptibility of artificial diamond | General test method for superhard materials | More targeted, more detailed parameter requirements |
| Measurement accuracy | Diamond magnetic susceptibility analyzerSensitivity: ≤0.1×10⁻⁵(SI) | ±0.2% (international general standard) | Higher requirements, better repeatability |
| Calibration cycle | Instrument: ≤1 year; Sample: No clear requirements | Equipment: Once every six months | Extended calibration interval, reduced costs |
3. Implementation suggestions and precautions
Instrument selection:It is recommended to use diamond magnetic susceptibility analyzer, which needs to be calibrated regularly to ensure measurement accuracy.
Key points for sample preparation:The drying process should be carried out at 110°C±5°C, and the standing time should be no less than 30 minutes.
Data recording suggestions:It is recommended to use a spreadsheet to record all measurement results and abnormal phenomena for subsequent analysis and traceability.
