Sodium Pyrosulfate Usage
Used as an acidic melting agent: It is commonly used in analytical chemistry and geological metallurgical industries to process and dissolve refractory metal oxides, special ceramics, refractory materials, and various refractory ores.
Fine functional material intermediates: Used in organic synthesis and inorganic salt manufacturing as special sulfonating agents, dehydrating agents, and raw materials for manufacturing other sulfur-containing special functional materials.
Industrial catalysts and special cleaning agents: Used as a characteristic catalyst component in the high-temperature gas-phase reactions of certain bulk chemicals; also used in the formulation of high-strength acidic removal solutions for special metal surface oxide scale.
