Low-cost computerized crystallizer unit

📗 Single crystal is a very essential for researchers and laboratories; we grow a large single crystal of TGS ferroelectric material, by using a low-cost automatic crystallizer unit controlled by a computer. The program used enables user to modify growth conditions such as decrement rate of temperature and motor speed. The study of the produced sample is important to judge the performance of the constructed unit. A well-known TGS sample was grown. Some physical properties were measured and they are all in a fair agreement with published data.
