Problems solved by technology

[0003] The general method of traditional room temperature liquid metal new material sample preparation is: according to the weight percentage of the formula, the pure metal raw materials of each component are smelted and mixed to make samples. In the actual preparation process, there are still the following problems: First, it is time-consuming and laborious. The preparation efficiency is not high, especially when it is necessary to prepare a large number of material samples, the preparation progress is slow and cannot meet the needs of research and development; second, when weighing each component in the material sample, the weighing accuracy is not high, and the actual material sample The components in the sample There is a deviation between the content and the theoretical value, which affects the accuracy of the test data of the material sample and leads to the distortion of the information of the material sample
