AI Technical Summary
Technical Problem
The existing technology for preparing large-size quartz bushings suffers from cumbersome machining and low deposition efficiency, and my country's level of domestic production is insufficient.
Method used
The target rod assembly consists of a hollow glass base tube and a solid carbon rod. A large-size silica porous body is formed by OVD deposition. Combined with pretreatment and vacuum sintering processes, a high-purity quartz bushing blank is formed, avoiding complex center hollowing and scouring processes.
Benefits of technology
This technology enables the efficient fabrication of large-size quartz bushings, simplifies the process, improves material utilization, and meets the fiber optic industry's demand for high-quality bushings.

Abstract
本申请涉及一种大尺寸石英衬套管制备方法，由于中空玻璃基管和内部的实心碳棒形成靶棒组件，使得在中空玻璃基管外沉积形成二氧化硅疏松体时，中空玻璃基管和内部的实心碳棒进行内部支撑，可以克服重力变形导致二氧化硅疏松体尺寸受限问题，可以制得尺寸更大的疏松体；另外在预处理和真空烧结阶段，由于抽出了实心芯棒，中空玻璃基管和其外的二氧化硅疏松体形成的结构，在后续无需再进行中心掏孔、衍磨等复杂加工，使得工艺简化。再者最终形成的石英衬套管毛坯，在后续工序中只需要简单研磨加工直接制得套管先端，同时由于不需要中心掏孔和衍磨，使套管原材料得到最大程度利用；当然也可以直接用于RIC制棒的外包层。
