Abstract

The invention discloses powder for reducing the consumption of a platinum-rhodium-iridium-nickel alloy. The powder comprises the following components: calcium, aluminum, sodium, silicon, zirconium, iridium, titanium, iron, potassium, magnesium and sulfur. The invention further discloses a production process of the powder for reducing the consumption of the platinum-rhodium-iridium-nickel alloy, and the production process comprises the following steps of S1, material selection, wherein the material is screened to remove impurities in the material, and the purity of the material is improved; s2, primary sintering, wherein the materials are smashed and then sintered at the temperature of 1,800 DEG C; S3, washing: washing and purifying the sintered and crushed material; and S4, secondary sintering: crushing the washed material, and sintering at 1450 DEG C again. According to the method, the powder replacing the platinum-rhodium-iridium-nickel alloy can be well prepared through a traditional material, so that the consumption of the platinum-rhodium-iridium-nickel alloy can be well reduced during use, the loss degree of the platinum-rhodium-iridium-nickel alloy can be reduced to 40%-60%, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of platinum-rhodium-iridium-nickel alloy, in particular to a powder for reducing consumption of platinum-rhodium-iridium-nickel alloy and a production process thereof. Background technique [0002] Platinum-rhodium-iridium-nickel alloy is a platinum-based quaternary alloy containing rhodium, iridium and nickel, which is a continuous solid solution at high temperature. Rhodium can improve the thermoelectric potential, oxidation resistance and acid corrosion resistance of the alloy to platinum. There are alloys such as PtRh5, PtRhl0, PtRhl3, PtRh30 and PtRh40. Alloys with more than 20% Rh are insoluble in aqua regia. Use a high-frequency furnace or an intermediate frequency furnace to protect the smelting with argon. Alloys below 20% Rh can be processed by cold working; alloys with more than 20% Rh can be processed by hot and cold processing; PtRh70 alloys can be processed by hot processing. Mainly used as...
