What are the quality evaluation indicators of artificial micron diamond powder?

The quality evaluation of artificial micron diamond powder mainly includes the following aspects：

1. Grain size standard:

The grain size of the micron diamond powder is the basis of its quality evaluation. Usually, the grain size composition is represented by three characteristic values of D10, D50, and D90.The three characteristic values represent the fine-end grain size, the median grain size and the coarse-end grain size respectively. The micron diamond powder with uniform grain size distribution and meeting the specific requirements has a better application effect.

2. Shape standard:

The grain shape is also an important evaluation indicator. It will not only affect the surface finish of the workpiece but also the durability of the micron diamond powder.

3. Impurity content:

The impurity content is a key indicator for evaluating the purity of the micron diamond powder. High-purity micron diamond powder has a low impurity content. This can improve the grinding efficiency and processing quality. According to the standard, the micron diamond powder of different grain sizes has different requirements for impurity content.

4. Physical properties:

Such as strength, thermal stability are also important indicators for evaluating the quality of the micron powder. Micron powder with high strength is less likely to break during the processing, and micron powder with good thermal stability can maintain stable performance in a high-temperature environment.

To sum up, the quality evaluation standards of artificial micron diamond powder cover multiple aspects, such as grain size, shape, impurity content and physical properties. These standards together constitute a complete system for evaluating the quality of micron powder.
