Hydrothermal Synthesis Of The Oxide Crystal

Oxide crystal is a important kind of crystals, oxide crystal is almost used in every field of technology and industry because of character in electricity optics and mechanism. With the development of science and technology, more and more oxide crystals are synthesized by more and more advanced technique,the new oxide crystals are incessantly synthesized and the new characters of oxide crystals are incessantly founded.Corundum dopped with impurity not only is cherished because of it's beautiful appearance,but also is used in the fields such as electrotechnics, mechanism, laser, the optic apparatus and the underlay of semiconductor.Sapphire dopped with Ti3+ is the best material of the tunable solid laser.ZnO crystal is material of the direct gap semiconductor(the width of forbidden band:3.37ev).The excited emission in ZnO crystal at room temperature has been found, so the ultraviolet luminescence in ZnO semiconductor can be acquired at room temperature.In this paper,oxid crystals were synthesized by the hydrothermal method, and the effects of the hydrothermal condition on shape and quality of crystal were studied by changing experimental temperature and mineralizer. On the base of these works the blue sapphire dopped with Fe,Ti and sapphire dopped with Ti were synthesized.Meantime,the effects of Ti,Fe-dopped on sapphire and what lead to the blue of sapphire were studied.In this paper a lot of experimental data about a -Al2O3 crystal with adulterant and ZnO crystal were acquired by studying the effects of the hydrothermal condition on the synthesized crystal.this paper also will provide guidance for hydrothermal industrialization and researching hydrothermal kinetic process.
