Shandong Lei Bao zirconium industry Polytron Technologies Inc predecessor was founded in 2001 in Zibo City, Zhoucun Lei Po refractory Co. Ltd in 2014 September limited the overall restructuring for the joint-stock companies, after the reform of registered capital of 40000000 yuan. The company is specialized in series of zirconium products R & D, production and sales of high-tech enterprises, is a new scientific research production enterprise in high purity refractory ceramic raw materials, high purity refractory ceramic products, high dense ceramic powder, ultra high temperature furnace material in one.
After more than ten years, the new technology of independent innovation R & D Lei Bao zirconium by sulfuric acid method of production of zirconium sulfate, production of this high pollution industries to provide green manufacturing technology solutions for zirconium sulfate, in the production of "Lei Bao" brand industrial zirconia and zirconia all kinds of products as the basis, to develop a self power upstream raw material recovery to the middle of various kinds of zirconium chemicals production of refined processing until all kinds of zirconia products industry chain. Products not only relates to the traditional field of iron and steel, chemical, refractories, and also extends to the optical fiber communication, artificial crystal, LED, artificial gem, nuclear safety and other emerging industries.
The company has a close cooperative relationship with the unit of Tianjin Institute of ceramics, electronic eleventh Institute of ministry, Shanghai Silicate Research Institute, Beijing Research Institute of synthetic crystals, University of Jinan, China Building Materials Science Research Institute, Shandong research and Design Institute of industrial ceramics and other established, and train a team of high quality staff. Company in 2008 by the Municipal Science and Technology Bureau identified as municipal engineering technology center, 2012 by the municipal development and Reform Bureau identified as municipal engineering laboratory, 2013 was the city letter by the Bureau recognized as a municipal enterprise technological centers, the existing 10 invention patents, 17 design patents, the company has won the "National high new technology enterprise" and "national first innovation business competition Excellence Award", "Zibo city science and Technology Progress Award" and "energy-saving outstanding achievement award", "Zibo City venture contest (entrepreneurial projects) Award" and other honorary titles.
Facing the increasingly severe market competition and the complicated and changeable international and domestic economic situation, the company will rely on the existing high-tech industry and talent advantages, adhere to the "quality of survival, science and technology innovation policy of" with quality, high-quality products, star level service, sales network throughout the country, a strong R & D strength, and strive to China new material of high-grade, internationalization and brand, strive for greater success returns, social returns.
