Problems solved by technology

[0004] The acid-soluble glass system of the micro-channel plate reported in the literature is also borosilicate glass. The system of this acid-soluble glass is relatively simple, and the silicon component in the glass is easy to adhere to the surface of the channel plate after pickling, and it is not easy to remove.

Abstract

The invention relates to micro channel plate borate core glass and a preparation method thereof. The micro channel plate borate core glass comprises the components by the molar fraction: B2O3 with the content of 33-63 mol%; BaO with the content of 25-40.5 mol%; La2O3 and Y2O3 with the total content of 3.5-9.0 mol%; Na2O, K2O, Rb2O and Cs2O with the total content of 0-8 mol%; MgO, CaO and SrO with the total content of 1-9.3 mol%; Al2O3 with the content of 1-8.5 mol%; TiO2 with the content of 0-5.6 mol%; and Nb2O5 and Ta2O5 with the total content of 0-4.5 mol%. The time of a corrosion process of the micro channel plate borate core glass is shortened, erosion of an acid solution on micro channel plate skin glass and edge-cladded glass is reduced, and thus the problems of deformation and breakage of a small-pore-diameter micro channel plate are solved.

Description

technical field [0001] The invention relates to the field of photoelectric materials, in particular to a microchannel plate borate core glass and a preparation method thereof. Background technique [0002] Microchannel Plate (MCP for short) is a component that multiplies electrons distributed in two-dimensional space. It has the characteristics of high gain, low noise, high resolution, broadband, low power consumption, long life and self-saturation effect. , and are widely used in low-light image tubes, photomultiplier tubes, camera tubes, and particle detectors. At present, the method of preparing MCP is the "solid-acid soluble" method. The key to the preparation of MCP is that the glass fiber used is drawn from an acid-soluble core material glass rod and a sheath glass tube together to form a fiber. Two kinds of glass fibers are regularly arranged into bundles, fused at high temperature and then cut into thin glass sheets, and then the core glass is removed by acid etchin...
