Problems solved by technology

[0004] At this stage, the input impedance of the instrument is low and cannot be maintained for a long time. The general method is to adjust the composition of the sensitive glass, usually to reduce the content of silicon dioxide and increase the amount of alkali metal oxide. However, this measure makes the glass The chemical stability is greatly reduced
Although there are a few glasses that simply add titanium pentoxide to reduce the resistance, the potential stability and chemical stability are poor.
PbF in prior art 2 -P 2 0 5 Binary system glass has large △T and S parameters, but its moisture resistance is very poor, and it is difficult to meet the requirements of high stability and high refractive index in practical applications. Therefore, it is necessary to produce a glass with high stability, low resistance, High photosensitivity materials have important practical significance

Abstract

The invention discloses a light-sensitive glass having high stability and low resistance. The light-sensitive glass is characterized by being prepared from the following raw materials in parts by weight: 30-40 parts of silicon dioxide, 12-15 parts of phosphorus pentoxide, 4-6 parts of lithium oxide, 4-6 parts of basic cerous carbonate, 5-7 parts of indium trifluoride, 2-4 parts of a resistance regulator, 3-5 parts of lead fluoride, and 2-4 parts of boron oxide. The resistance regulator is added, so that the glass has low resistance which is one-sixth to one-seventh of the internal resistance of common light-sensitive glass; the basic cerous carbonate is good in forming and size uniformity. The raw materials are low in cost and are easy to obtain, and when the raw materials are used for the glass, the quality stability of glass products can be improved; the indium trifluoride in a system can regulate the refractive index of the glass, the glass system consisting lead and indium can effectively raise the transition temperature of the glass and improve the stability of the glass, and the physical chemistry performance of the glass is improved.

Description

technical field [0001] The invention belongs to the technical field of glass, in particular to a photosensitive glass with high stability and low resistance. Background technique [0002] Glass is a transparent, airtight, and hard material. Glass is chemically inert in everyday environments and does not interact with living things. Glass is generally insoluble in acids but slightly soluble in strong bases such as cesium hydroxide. [0003] Basic cerium carbonate is an important rare earth compound. Due to its unique optical properties and chemical properties caused by the special 4f electron layer inside it, it has been widely concerned by the material industry and used in many fields, such as a stabilizer for the glass industry. . Therefore, designing and fabricating basic cerium carbonate materials with different morphologies has received more and more attention for the development of its application fields, and it is also an increasingly important research field at the...
