moffbadger: So this is a Scanning Electron Microscope (SEM) photo I took today of one of my samples of tungsten (VI) oxide, this is the sample marketed as <20 micrometers (10^-6 m ) in diameter. As you can see there are some particles that at bigger than this which tells you that suppliers can’t be trusted with what they say… But It also shows that the particles are not regular shapes which can effect the stability of the emulsions formed with them. This was what the powder looks like as it has been supplied, if I was to sonicate this the particles should be much smaller on average I just thought it was a really nice picture and there you go -- source link
