The global market for evaporation materials was pioneered by established suppliers from Germany and Japan, such as Heraeus and Tanaka, who set the initial benchmarks for high-purity standards. Their development was driven by the demanding needs of the growing semiconductor and optics industries, which required unparalleled material consistency and performance for thin-film deposition.
A diverse range of materials is used in evaporation processes. This includes highly conductive metals like Silver, Gold, Aluminum, and Copper for electronics, as well as refractory metals such as Tungsten and Molybdenum for their high-temperature stability. Various oxides and alloys are also employed to achieve specific functional coatings.
In China, the production of evaporation materials began decades later, initially emerging from state-owned research institutes in the late 20th century focused on strategic projects. This foundational work has since been commercialized, with private companies now like us leading the charge in scaling up production and refining purification technologies to compete on a global scale. With self-owned patented technology, equipment, experienced staff and professional engineer team, we have accomplished the quantities of 2000 tons this year and delivering our products to Europe, America, Asia etc. because of reliable quality, ISO management system, REACH passed and competitive cost.
Standing at the forefront of this development is Tianjin Ruiyuan Electric Materials Co., Ltd. We have positioned ourselves as a highly competitive supplier by focusing on what matters most in a production environment: reliability and yield.
