Specification for diamond micropowder GB/T 23536-2009 specifies that the diamond micropowder has the code name MPD and the particle size is M0/0.5~M36/54. The standard refers to the JB/T7990-1998 standard, which specifies the diamond micron particle size and size range standards as shown in the table:
Diamond micron particle size standard(JB/T 7990-1998)μm | ||||
Particle size | Nominal size range D | Coarse grain maximum size D max | Fine particle minimum size D min | Particle size composition |
M0/0.5 | 0~0.5 | 0.7 | --- | 1. No particles larger than the maximum size of the coarse particles. 2. The coarse content should not exceed 3%. 3. Fine particles content: fine particle size within M3/6 shall not exceed 8%; fine particle size from M4/8 to M10/20 shall not exceed 18%; fine particle size from M12/22 to M36/54 shall not exceed 28%. 4. The finest content: no more than 2% of each particle size. |
