Dispersion strengthened material used for platinum-based vessel and preparation method and application of material

Abstract

The invention provides a dispersion strengthened material used for a platinum-based vessel. The dispersion strengthened material comprises a substrate and a strengthening phase dispersed in the substrate, wherein the substrate is platinum and the strengthening phase element is any one or more of zirconium, scandium and cerium. The zirconium content is more than 0 and no more than 0.4 wt%, the scandium content is in a range of 0-0.4 wt%, and the cerium content is in a range of 0-0.4 wt%, with the balance being platinum, wherein the total content of zirconium and scandium and cerium is less than0.6 wt%. The strengthening phase element is dispersed in the substrate in an oxide form to form a dispersion strengthened material. The dispersion strengthened material is good in scouring resistance, corrosion resistance and high-temperature creep resistance. A vessel prepared from the material is long in service life. The production cost in the technical fields, such as optical glass and glassfiber, can be efficiently reduced.

Description

technical field [0001] The invention relates to the field of precious metal materials, in particular to a dispersion-strengthened material used for platinum-based vessels and its preparation method and application. Background technique [0002] In the production process of optical glass, glass fiber and other industrial fields, it needs to be smelted and formed in platinum vessels. Due to the harsh working conditions, the material of the vessel is required to have strong deformation resistance, erosion resistance, and corrosion resistance under high temperature conditions, so as to ensure the service life of the alloy vessel, reduce the loss of platinum, and achieve the purpose of reducing production costs. [0003] However, at present, utensils made of commonly used platinum materials cannot meet the expected requirements in terms of deformation resistance, erosion resistance, and corrosion resistance under high temperature conditions, making the utensils made of these mate...
