1. The wall-broken Rate of Safflower Micropowder is 96.40%.

2. Micropowder of mullite is manufactured by gap mill.

3. Micropowder magnesium oxide is a new high functional fine inorganic material.

4. The status of research and major achievements in the research of micropowder formation with supercritical fluids were reviewed.

5. Methods:Cytometry was used to investigate the influence of ultra-pulverization on Raidix Paeoniae Alba, and wall-broken rate on Raidix Paeoniae Alba micropowder was also determined.

6. The series of tackifiers are manufactured high-grade high-alumina powder, corundum powder, micropowder inorganic bonder and additional agent.

7. In the study, a Cytometry is used to investigate the impact of ultra-pulverization on Safflower, and to determine the wall-broken rate of Safflower micropowder.
