Often an extreme challenge Probably one of the most difficult tasks was the fine distribution of pure liquid mercury in a mixture of fine solid metal powders. Already during the manual mixing with a spatula, with careless work methods without a problem up to 3 mm large amalgam grains were produced. The solution was added to the Mortar Grinder PULVERISETTE 2, with an agate grinding set and special adjustments for the minimizing of the application of energy found. From the area of mixtures liquid – solid is the production of filled pastes to be mentioned. Especially challenging here is to add as much as possible solids in the high viscosity organic phase. An additional example for this is, when one has to add to organic binder (for example synthetic resin or varnish or in the simplest case oil) fine metallic, ceramic or inorganic powders. High viscosity pastes evolve which can be compared with shoe polish in a tube. Experts often talk about filled composite materials. Often the increase
