Nanopowder plays an important role in sintering process, so the significance parameters, such as time and temperature are different during sintering process.
Compared to micro, nano particles exposes more (exponentially high) surface area. That is the key point in any process - not just microsintering
- look in that perspective
Micropowder physical properties have just the same as that for the bulk state, for example the melting temperatur which is important in your case. The properties in the nanoscale size powder changed strongly according to its size. For example its melting temperatures decrease to a state that the powder may melt at a temperature much less than its melting point or the material may be in a liquid state at rome temperature. If the micro and nanopowder are mixed, the mixture could transfer to a solid bulk material after facing a small pressure.
The material compactness or densification will be of a high order and a dense bulk will result.
