Hydrothermal reactor/high pressure autoclave offers many advantages for synthesis over conventional wet precipitation reactions. Here we can apply high pressure and a maximum temperature of 300 Deg C. The method is particularly suitable for the growth of large good-quality crystals while maintaining control over their composition and morphology. This is a highly effective method for controlled synthesis of functional nanomaterials- nanoparticles, single crystals, core shells, cultured crystal growth, etc.  Prevest Research Institute uses a stirred high pressure autoclave made from SS 316. Model: A2000 Series from Amar equipments, with a 2L net filling capacity and Magnetic drive coupling, for turban Stirring in the range100-1450 RPM.
