Abstract

The invention relates to a micro-channel plate cladding glass, a micro-channel plate, and a preparation method thereof. The micro-channel plate cladding glass comprises the following components in parts by weight: 52 to 57 parts of SiO2, 0 to 2 parts of Al2O3, 1 to 4 parts of B2O3, 15 to 18 parts of Bi2O3, 5 to 7 parts of SnO2, 2 to 4 parts of In2O3, 0.5 to 2 parts of Sb2O3, 8 to 10 parts of Na2O and Cs2O, and 6 to 8 parts of MgO, CaO, and BaO. The micro-channel plate cladding glass and micro-channel plate prepared therefrom have the characteristics of non-toxicity, innocuousness, and environment-friendliness.

Description

technical field [0001] The invention relates to an inorganic non-metallic material technology, in particular to a microchannel plate leather glass, a preparation method thereof and a microchannel plate. Background technique [0002] Micro-channel Plate (MCP for short) is an advanced thin-chip electron multiplier device, which has the characteristics of high gain, low noise, high resolution, long life, self-saturation effect, etc., and is widely used in low-light image tubes , photomultiplier tubes, camera tubes, and particle detectors. For a long time, the leather glass of MCP, which is most widely used in various fields such as low-light night vision, is lead silicate glass. Microchannel plates of different eras, different application environments, and different manufacturers may have different specific components or contents of glass materials, but they all belong to the silicate glass system containing lead and bismuth. After decades of application and development, the ...
