Study Of The Growth Of Rutile Single Crystal With Flame Fusion Method And Irradiated Physical Properties

Rutile single crystal has been strongly interested because of its variability of physcal properties and particularity of photochemical characteristics afer it was artificially grown by C. H. Moore in 1949. It has been applied in opt-communication, solar light energy conversion and jewels. But it is difficult to grow big and perfect rutile with flame fusion method on domestic SJZ sintering machine for its special atmosphere in growth. Through this article work, the perfect rutile has been got with flame fusion method in developed domestic SJZ sintering machine for the first time in china. Based on it, the study of the electrical property of irradiationed rutile by high dose neutron has been also made. The achievements are concluded in the following: (1) Through the development of technology of TiO? ultrafine powder, the high quality ultrafine power has been got.(2) The perfect rutile has been got with flame fusion method in developed domestic SJZ sintering machine, and the technology of crystal growth has been clearly analyzed. In the end the suitable techniche has been got on the basis of systemic study on the conditions of growth.(3) Through the study of electrical property of irradiated rutile by high-dose neutron, the curse of relationship of conductivity and temperature has been abtained. According to this relationship, the conducting behavior in diflrent temperature is also studied.Except some conclusions reported in article, most of them have also not beenpublished. And it is the first time to successfully artificially grow rutile single crystal with flame fusion method in china.
