Laboratory Nanostructures IWC PAN is an expert in the synthesis of doped nanoparticles with small size distribution using microwave technology solvothermal synthesis (MSS). MSS technology allows precise control parameters of nanoparticle synthesis such as reaction time, temperature and pressure. We obtain the zinc oxide particle size distribution in solvothermal synthesis which can be expressed as follows:
(CH3CO2) 2Zn  → ZnO

Synthesis of nano-zinc oxide doped with cobalt take place in solution of ethylene glycol during 12 minutes in microwave reactor MSS2. Specific surface doped ZnO is 10-50 m2/g and crystallites size are in a range from 20 to 150 nm.

Microwave, pressure chemical reactor MSS2 is used to carry out solvo- and hydrothermal microwavesynthesis, wherein is obtained nanopowders with specific particle size and morphology. Used  solutions in the reactor overtake a global level and allows to obtain ultrapure nanoparticles in the production and experimental scale. Developed high-pressure seals provide insert of substrates, running processes, released products in track made ​​from chemically inert materials.
