High-purity inorganic chemicals
High-purity inorganic chemicals support cutting-edge technologies as essential components of semiconductors and electronics.
Toagosei manufactures high-purity products as raw materials for industrial chemicals such as caustic soda, caustic potash, chlorine, and hydrochloric acid.
We have an integrated production line that spans from raw materials sourcing to high-purity finished products. Eliminating intermediate shipments also helps to eliminate the risk of contamination.
Our products have established a strong track record of success in the semiconductor, electronic material, and pharmaceutical industries for their high purity and stable quality.
Main Products
Liquid hydrogen chloride (general and high-purity)
Used in epitaxial processes for semiconductor manufacturing and in the manufacture of intermediates for pharmaceuticals and pesticides.
High-purity potassium hydroxide aqueous solution
- Product names
- Liquid Caustic Potash L-HM, Super Potash Ex, and Super Potash R
We refine the potassium hydroxide aqueous solution produced during electrolysis with saline solution into a product that contains fewer metal impurities. This is used in electronic materials and as an intermediate raw material for pharmaceuticals and pesticides.
High-purity potassium carbonate aqueous solution
We manufacture high-purity potassium carbonate aqueous solution for use in electronic materials and as a raw material for high-purity chemicals.
High-grade iron (III) chloride solution
An iron (III) chloride solution with a reduced amount of other heavy metals.
Used in metal etching and pigments.
EL sulfuric acid
EL sulfuric acid is used as a cleaning solution in the semiconductor manufacturing process and as a chemical solution in the manufacturing process for LCD displays.
