Cerium(Ⅳ) Hydroxide (Ce(OH)4) (CAS No.12014-56-1)

Description of product

Cerium hydroxide has good optical properties, electrochemical properties and catalytic properties, so IT is widely used in TFT-LCD (thin film transistor liquid crystal display), OLED (organic light emitting diode), LCOS (reflective liquid crystal display), automobile exhaust purifying agent and IT industry. It is also used to prepare ceric ammonium nitrate, ceric sulfate, ceric ammonium sulfate and other chemical reagents. WONAIXI company (WNX) started pilot production of cerium hydroxide in 2011 and officially put into mass production in 2012. We continuously improve the production process in order to provide customers with high-quality products, and with an advanced process method to apply for cerium hydroxide production process national invention patent. We have reported the research and development achievements of this product to the national science and technology department, and the research achievements of this product have been evaluated as the leading level in China. At present, WNX has the annual production capacity of 2,500 tons of cerium hydroxide.
