Industrial Applications of POTASSIUM TETRABORATE TETRAHYDRATE
| Industry | Application | Process |
|---|---|---|
| Welding and Metal Processing | Welding Flux | Used as a flux component in welding materials (e.g., for aluminum and aluminum alloy brazing) to remove metal surface oxides, improve wettability, and facilitate smooth welding. |
| Metallurgical Industry | Refractory Material Additive | Added to refractory slurries or ceramic cores in casting processes to provide binding and curing functions, enhancing the refractoriness and strength of molding sands. |
| Surface Treatment | Metal Surface Treatment Agent | Employed in metal surface cleaning, rust removal, or rust inhibition processes as a component of alkaline cleaners or rust inhibitors, forming a protective film on the metal surface. |
| Ceramics and Enamels | Glaze Flux | Applied as a flux and melting agent in the firing process of ceramics or enamels to lower glaze melting temperature and improve gloss and flow characteristics. |
| Glass Manufacturing | Specialty Glass Additive | Used in the melting process for heat-resistant or optical glass production to adjust thermal expansion coefficient and enhance chemical stability and transparency. |
| Agriculture | Micronutrient Fertilizer | Serves as a raw material for boron fertilizers, applied via soil fertilization or foliar spray to supply boron to crops and support growth and pollen development. |
| Chemical Industry | Chemical Reagent and Buffer | Utilized as a chemical reagent or component of buffer solutions in laboratory analysis or fine chemical synthesis to regulate and control solution pH. |
Manufacturing Quality Control of POTASSIUM TETRABORATE TETRAHYDRATE
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe the sample's color, physical state, lumping, and visible impurities under natural light or standard illumination. |
| Identification | Infrared Spectroscopy (IR) | Prepare a potassium bromide pellet of the sample, measure its infrared absorption spectrum, and compare it with the reference spectrum to confirm consistency of characteristic molecular peaks. |
| Content Determination | Acid-Base Titration (pH Titration) | In weakly acidic conditions, add mannitol to enhance the acidity of boric acid, then titrate with standardized sodium hydroxide solution to calculate the content of tetraborate ions. |
| Moisture (Crystalline Water) | Karl Fischer Titration | Use Karl Fischer reagent to quantitatively determine the water content in the sample, suitable for precise measurement of crystalline water and adsorbed water. |
| pH Value | pH Meter Measurement | Determine the acidity or alkalinity of a sample solution (e.g., 1% w/v) using a pH meter to assess the solution properties after dissolution. |
| Chlorides | Silver Nitrate Turbidimetric Method | React chlorides with silver nitrate in nitric acid medium to form a white turbidity; compare the turbidity with that of a standard chloride reference solution for limit testing. |
| Sulfates | Barium Chloride Turbidimetric Method | React sulfates with barium chloride in hydrochloric acid medium to form a white precipitate; compare the turbidity with that of a standard sulfate reference solution for limit testing. |
| Heavy Metals | Sulfide Colorimetric Method (e.g., Chinese Pharmacopoeia method) | After sample treatment, react in weakly acidic conditions with hydrogen sulfide or thioacetamide to generate colored metal sulfides, then compare with a standard lead solution for quantitative assessment. |
| Loss on Ignition | Gravimetric Method (High-Temperature Calcination) | Ignite the sample at a specified temperature (e.g., 300–800°C) until constant weight is achieved, measuring the mass loss to evaluate crystalline water and volatile impurity content. |
| Particle Size Distribution | Laser Particle Size Analysis | Use a laser particle size analyzer to analyze particle size distribution of the sample suspension or dry powder, assessing product uniformity and suitability. |
| Microbial Limit Test | Microbial Limit Test (Pharmacopoeial Method) | Includes total aerobic bacteria count, total mold and yeast count, and control organism testing (e.g., Escherichia coli); assessed via culture methods to evaluate microbial contamination. |
