Industrial Applications of Potassium borate
| Industry | Application | Process |
|---|---|---|
| Glass & Ceramics | Flux; glaze component | Applied during glass and ceramic firing to lower melting temperature, improve surface gloss, and enhance mechanical properties |
| Agriculture | Trace element fertilizer (boron source) | Applied as a boron fertilizer to soil or foliage to correct boron deficiency in crops |
| Flame-Retardant Materials | Flame-retardant additive | Formulated with other flame retardants for use in plastics and textiles to improve fire resistance |
| Cleaning Agents | Buffer; builder | Used in industrial cleaning formulations to adjust pH and enhance soil removal |
| Metallurgy | Flux for molten metal processing | Applied as a flux during metal welding or refining to remove oxide impurities |
| Chemical Reagents | Laboratory reagent | Used in analytical chemistry for buffer solution preparation or boron standard solution preparation |
Manufacturing Quality Control of Potassium borate
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, physical state, and whether it is caked. The product should be white crystalline powder or colorless transparent crystals, free from visible impurities. |
| Main Component Content (K₂B₄O₇) | Acid-Base Titration (Mannitol Enhancement Method) | In a weakly alkaline medium, add polyols such as mannitol to enhance the acidity of boric acid, then titrate with standard sodium hydroxide solution to determine the tetraborate content. |
| pH Value | pH Meter Method | Dissolve the potassium tetraborate in water to a specified concentration (e.g., 1% w/v), then measure the pH of the solution using a calibrated pH meter. The typical range is 9.0–9.6. |
| Chlorides | Silver Nitrate Turbidimetry | In a nitric acid medium, chlorides react with silver nitrate to form a white turbidity. The chloride ion level is determined by turbidimetric comparison. |
| Sulfates | Barium Chloride Turbidimetry | In a hydrochloric acid medium, sulfates react with barium chloride to form a white precipitate. Sulfate content is measured by turbidimetry. |
| Heavy Metals (as Pb) | Lead Sulfide Colorimetry (or Atomic Absorption Spectroscopy) | In a weakly acidic solution, heavy metals react with sodium sulfide to form colored sulfides for colorimetric quantification; alternatively, AAS or ICP-MS can be used for precise measurement. |
| Arsenic Content | Guo Cai's Method (or Arsenic Spot Test) | React metallic zinc with acid to generate nascent hydrogen, which reduces arsenic compounds in the sample to arsine gas. The gas reacts with mercuric bromide paper to produce a colored spot; the intensity is compared to assess arsenic levels. |
| Loss on Drying | Gravimetric Loss on Drying | Dry the sample at 105°C until constant weight is achieved. Calculate the percentage loss due to volatile substances, including moisture. |
| Residue on Ignition | Gravimetric Method | Ignite the sample at high temperature and weigh the residue to estimate the total amount of inorganic impurities. |
| Particle Size Distribution | Sieve Analysis or Laser Diffraction | Determine particle size distribution using standard sieves or a laser particle size analyzer to ensure compliance with process requirements. |
