Numerical simulation of the hydrothermal process for growing two-inch bulk single crystals of ZnO has been done. The autoclave is assumed to be axisymmetric. The heat transfer by natural convection is discussed for flat and funnel-shaped baffles. The

The sealed vertical Bridgman (VB) method is the main technique used to grow SrI2(Eu) crystals because SrI2(Eu) is very hygroscopic. In this study, we grew SrI2(Eu) single crystals with two-inch diameters and four-inch lengths using the VB method equi
