Preparation method of transparent ceramic optical fiber with core-spun structure
The invention discloses a preparation method of a transparent ceramic optical fiber with a core-spun structure. The preparation method comprises the following steps: respectively preparing ceramic paste Re: M suitable for a core layer and ceramic paste N suitable for a coating layer; Transferring Re: M and N into a liquid storage device A and a liquid storage device B respectively, adjusting the air pressure P1 inputted into the liquid storage device A through a flow dividing pressure control valve A, adjusting the air pressure P2 inputted into the liquid storage device B through a flow dividing pressure control valve B, and therefore the speed of the two kinds of ceramic paste Re: M and N entering a nozzle cavity is accurately controlled; promoting the interior of the extruded ceramic composite paste to realize rapid curing molding through a temperature control device; and carrying out low-temperature degreasing, high-temperature solid-phase reaction sintering and post-treatment on the formed transparent ceramic optical fiber to obtain the transparent ceramic optical fiber material. The transparent ceramic optical fiber with high optical quality is prepared by combining a ceramicpaste extrusion process with a high-temperature solid-phase reaction sintering method, and the material has the advantages of good heat-conducting property, simplicity in operation, controllable conditions and easiness in popularization.
本发明公开了一种具有包芯结构的透明陶瓷光纤的制备方法，步骤是：分别制备适用于芯层的陶瓷膏体Re:M与适用于包覆层的陶瓷膏体N；将Re:M、N分别转移至储液器A和储液器B中，通过分流控压阀A调整输入储液器A的气压P1，通过分流控压阀B调整输入储液器B的气压P2，从而精确控制两种陶瓷膏体Re:M、N进入喷嘴腔体的速率；挤出后的陶瓷复合膏体通过温度控制装置促进陶瓷膏体内部实现快速固化成型；将成型后的透明陶瓷光纤丝进行低温脱脂、高温固相反应烧结及后处理，获得透明陶瓷光纤材料。本发明采用陶瓷膏体挤出工艺再结合高温固相反应烧结方法制备出高光学质量的透明陶瓷光纤，该材料具有良好的导热性能，操作简单，条件可控，易于推广。
