HOME > Product Information and MSDS > Products for Electronics industries / High Purity Liquefied Potassium Hydroxide The high purity and high performance caustic potash is needed in the semiconductor industries (for example the cleaning process of Si wafer etc.). The quality to correspond to the quality at the Nano device level is set day by day high. Tsurumi Soda’s unique alkali purification technology has reduced impurity levels less than 10ppb. Up to now, caustic potash at this quality level did not exist. We have the patent to supply this quality with stability. - This is the liquid form product. This is better than solid product because liquid product is handled easily for dissolution and density adjustment. - CLEARCUT(R)-P has lowest impurity specification guarantees (major metals less than 10 ppb). - Fluoroplastics is used for all production equipments (pipes, tanks, etc.) to prevent pollution. - We have the analysis technology with the updated equipment such as ICP-MS and ICP-AES. - Si wafer etching, cleaning, CMP slurry - Intermediary materials for pharmaceuticals and agriculture, CIP cleaning - Synthetic quartz, lens production, cleaning - Peeling of the ITO resist on LCD - Cleaning of glass substrates - Raw material of high quality inorganic reagents     CLEARCUT(R)-P Content KOH 48.01.0% Potassium Carbonate K2CO3 0.1% Chlorides Cl 1ppm Copper Cu 10ppb Iron Fe 10ppb Chrome Cr 10ppb Nickel Ni 10ppb
