A glass with high mechanical strength and its manufacturing method

Abstract

The present invention provides a glass with high mechanical strength, more specifically the chemical composition of the glass material used to make the solid edge of a bulk conductance microchannel plate, and a method of making the glass. This method is used to improve the mechanical strength of bulk conductance microchannel plate, especially the strength of products with small aperture and thin thickness. The invented glass can be well fused with semiconducting vanadium phosphate glass under hot pressing.

Description

A kind of glass with high mechanical strength and manufacturing method technical field The present invention relates to the field of glass materials, more particularly to a kind of glass with high mechanical strength and a manufacturing method thereof Compared with the vanadium phosphate glass which is the main material of the bulk conductance microchannel plate, the glass of the present invention has higher mechanical strength. Background technique Ordinary microchannel plate is made of non-conductive glass material, and the product is heated and passed through hydrogen to make the surface chemically restored. The primary reaction forms a conductive layer on the surface, so that the microchannel plate has the function of amplifying the electronic signal. Due to the chemical activity of the conductive layer High performance, the conductive layer tends to age during operation and release cations such as hydrogen gas in the microchannel to form interference noise.
