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 potash, 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.
