  Avoiding clumps

  Posted by natiyo123 on April 24, 2021 at 9:18 am

  I want to disperse zinc oxide (non nano) in vaseline. I have tried melting the vaseline then added the zinc, and mixed with a magnetic stirrer, but at the end I always end up with a lot of clumps even if I use high speed. How can I achieve an homogeneous dispersion and avoid clumps? (technique or equipment I can use?)
