Our History Relying on founder鈥檚 rich experience and expertise in the field of alumina, our company was founded in 2002 , since 2004, we are specializing in the production, development and marketing of high-purity alumina.In 2009, we renamed and re-registered "Honghe" Company. In 2011, in Gaoqing County Economic and technological development zone, we invested the construction of a new production base-Zibo Honghao Crystal Materials Co., Ltd., and put into operation in 2012. The company has been focusing on high purity alumina as well series of its products.By virtue of its chemical stability ,high melting point, high mechanical strength, high hardness, good thermal conductivity, high insulation and other properties , our high purity alumina can meet requirements on electronic materials, technical ceramics, precision polishing, functional additives, catalyst, spraying materials, semiconductor materials and crystal materials and other high-quality applications, and its future application prospects are even more sustainable. The company has passed ISO9001-2015 quality system certification and ISO14001-2015 environmental system certification, as well as the European Union REACH certification and the European Union ROHS certification. We will continue to meet market demand through excellent service, innovation and stable quality. Our Factory Our factory was founded in 2011 in Gaoqing,Zibo and put into operation in 2012.
