I. Glass Manufacturing Industry

This is the primary application field for industrial-grade heavy potassium carbonate, accounting for over 40% of its consumption:

• Specialty Glass Production: Heavy potassium carbonate serves as a fluxing and clarifying agent in glass, reducing the melting temperature and improving fluidity and transparency. For example:
  • Used in producing optical glass (e.g., eyeglass lenses, camera lenses) to enhance refractive index and light transmittance;
  • Employed in manufacturing potassium glass (also known as hard glass), which features high hardness and excellent heat resistance, suitable for chemical apparatus (e.g., beakers, test tubes) and high-temperature glass products;
  • Applied in electronic glass (e.g., display substrate glass) to improve chemical stability and mechanical strength.
• Glass Surface Treatment: In glass polishing and etching processes, heavy potassium carbonate acts as an alkaline medium to assist in removing surface impurities or creating specific textures.

II. Chemical and Pharmaceutical Intermediates

• Chemical Synthesis: As an alkaline raw material, it participates in various organic chemical reactions, such as:
  • Used in preparing potassium salts, which are fundamental raw materials for fertilizers, explosives, pharmaceuticals, and other industries;
  • Employed in neutralization reactions, deacidification reactions in organic synthesis, or as a catalyst carrier for producing fragrances and dye intermediates (e.g., anthraquinone dyes).
• Pharmaceutical Field: Serves as a pH regulator or raw material in the synthesis of certain drugs, such as antibiotics and diuretics; its high purity meets the requirements for pharmaceutical-grade excipients (further purification needed).

III. Printing, Dyeing, and Textile Industry

• Dyeing Auxiliaries: Heavy potassium carbonate functions as an alkaline agent in fabric dyeing and printing processes:
  • In reactive dyeing, it adjusts the pH of the dye bath to promote dye-fiber (e.g., cotton, linen) bonding, improving dye uptake and color fastness;
  • Used in the color development process of vat dyes to fix dyes on fibers;
  • Acts as an auxiliary in desizing and scouring to remove impurities (e.g., sizing agents, waxes) from fibers, enhancing fabric absorbency.
• Fabric Finishing: Applied in treating protein fibers like wool and silk to improve hand feel and luster while enhancing wrinkle resistance.
