Claims29
A sintering powder comprising:
- a particulate, wherein the particulate comprises:
- from 1 to 19 wt % of a first type of metal particles having a mean longest dimension of from 100 nm to 20 μm, wherein the first type of metal particles is at least partially coated with a first capping agent comprising oleic acid and has a D50 of from 1 to 3 μm;
- from 81 to 99 wt % of a second type of metal particles having a mean longest dimension of from 5 to 75 nm, wherein the second type of metal particles is at least partially coated with a second capping agent comprising octylamine;
- and
- a total capping agent concentration of up to 5 wt %.
