However, this also changes the network structure of Al-P glass, further affecting its optical properties, such as UV transmittance, infrared absorption and other properties
In addition, the addition of a large amount of silicon dioxide will lead to the transformation from pure glass phase to glass-ceramic phase, which greatly affects the transparency of phosphorus-aluminum glass and limits its application in electronic glass, optical glass and other fields.

Abstract

The invention discloses a method for preparing a particle composite aluminum-phosphorus glass material, which comprises: mixing raw materials for preparing aluminum-phosphorus glass, heating to an initial temperature A until all raw materials are completely melted to obtain an aluminum-phosphorus glass melt; melting the aluminum-phosphorus glass After the body cools down to the middle temperature B, disperse the quartz glass micro-nano particles in the aluminum-phosphorus glass melt, stir evenly, pour it into a mold for molding, then cool down to the heat treatment temperature C and keep it for a period of time, after post-treatment, the particle-composite aluminum-phosphorus glass is obtained Material; on the basis that the sum of the total weight of the raw materials of the aluminum-phosphorus glass and the weight of the quartz glass micro-nano particles is 100%, the addition amount of the quartz glass micro-nano particles is 0.1-0.5 wt%. The preparation method disclosed in the present invention greatly improves the hardness, stiffness and chemical stability of the aluminum-phosphorus glass material without changing the properties of the aluminum-phosphorus glass or reducing its transparency, and is especially suitable for preparing electronic glass and optical glass.

Description

technical field [0001] The invention relates to the technical field of alumino-phosphorus glass materials, in particular to a method for preparing a particle-composite alumino-phosphorus glass material and its product, as well as its application in preparing electronic glass and optical glass. Background technique [0002] Phosphate glass system is one of the most widely used glass systems at present. It can be used in electronic glass, Optical glass, biological glass and other special glasses. Among them, the addition of intermediate alumina can stabilize the structure of phospho-oxygen glass and improve its network density and connectivity. Therefore, phosphor-aluminum glass is widely used in electronic devices, lasers, bone fillings, etc., but the aluminum-oxygen network structure is due to the angle and bond The uneven growth makes it difficult to eliminate the residual stress and increase the viscosity of the aluminum-phosphorous glass during the forming process, so th...
