| Abstract: | In order to measuring the true density of organic powder accurately and quickly,how to determinate the organic powder true density using pycnometer ultrasound settlement method and the factors that effected on the determination results were discussed.The process for determination of powder density was introduces and the calculation formula of the density was proposed.Finally,through discussing the three methods,determing organic powder true density by ultrasonic method was more accurate. |
| Keywords: | powder density pycnometer precision |
