【Abstract】 The silver halide fibers[AgCl x Br (1- x ) ,0≤ x ≤1] are the well transparent medium for transmitting laser at middle infared wavelength and the fibers can be used for CO 2 laser surgery in medicine. The starting materials of silver halide were puried by smelting at high vacuum(physical nurinwtion) and were ultrapurified by horizontal zone melting purification at Cl 2 atmosphere(physical and chemical purification). The silver halide fibers were made by hot extrusion. Two kinds of handpiece, comventional model and especial model(use for mouth, nasal cavity and other cavities), were used as the outlet end of arms.更多还原
