Industrial Applications of Strontium sulfate
| Industry | Application | Process |
|---|---|---|
| Glass manufacturing | Used in the production of cathode-ray tube (CRT) glass, CRT envelopes, and other specialty glasses | Added to the glass batch as a flux and X-ray absorber; eliminates bubbles and absorbs X-rays during high-temperature melting |
| Pyrotechnics manufacturing | Used in red pyrotechnic signal compositions and tracer compounds | Blended with oxidizers (e.g., potassium chlorate) and fuels (e.g., magnesium powder), then pressed into granules or loaded into pyrotechnic tubes; produces bright red flame upon combustion |
| Ceramics industry | Used in the production of premium glazed tiles and ceramic glazes | Incorporated as a glaze component during formulation; enhances whiteness, gloss, and chemical resistance of the fired glaze surface |
| Magnetic materials | Used in the production of ferrite permanent magnets | Served as a primary raw material, mixed with metal oxides (e.g., iron oxide), and sintered via solid-state reaction to produce anisotropic strontium ferrite magnets |
| Electronics industry | Used in the production of PTC thermistors | Employed as a dopant or principal raw material in ceramic slurry synthesis; processed through shaping and sintering to yield semiconductor ceramics exhibiting positive temperature coefficient behavior |
| Chemical industry | Precursor for other strontium salts (e.g., strontium carbonate, strontium nitrate) | Reacted with sodium carbonate (soda ash) or ammonium carbonate via double decomposition to precipitate strontium carbonate; or reacted with nitric acid to produce strontium nitrate |
Manufacturing Quality Control of Strontium sulfate
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| SrSO4 Content | Gravimetric Analysis | Precipitation of sulfate as BaSO4 after dissolution and separation, followed by weighing of dried precipitate. |
| Strontium (Sr) Content | ICP-OES | Quantification of Sr atoms by measuring characteristic emission intensities after plasma atomization and excitation. |
| Sulfate (SO4) Content | Barium Chloride Titration | Titration of sulfate with standardized BaCl2 solution using potentiometric or visual endpoint detection. |
| Loss on Ignition (LOI) | Thermogravimetric Analysis | Mass loss measured after heating sample to 900-1000 C to remove volatiles and decompose carbonates/hydrates. |
| Water Soluble Matter | Gravimetric Analysis | Extraction with hot distilled water, filtration, evaporation of filtrate, and weighing of residue. |
| pH of Aqueous Suspension | Potentiometric Measurement | Measurement of H+ activity in a defined suspension (e.g., 10 g/L in water) using calibrated pH electrode. |
| Heavy Metals (as Pb) | AAS (Flame or Graphite Furnace) | Atomic absorption measurement of total heavy metals after acid digestion, reported as lead equivalent. |
| Chloride (Cl) | Argentometric Titration | Titration with standardized AgNO3 solution using K2CrO4 indicator or potentiometric endpoint. |
| Iron (Fe) | ICP-OES | Quantification of Fe by plasma-excited atomic emission at characteristic wavelength following acid digestion. |
| Insoluble Matter in HCl | Gravimetric Analysis | Filtration of acid-digested sample, washing, drying, and weighing of residue insoluble in dilute HCl. |
| Particle Size Distribution | Laser Diffraction | Analysis of light scattering pattern from dispersed particles to determine size distribution by Mie theory. |
| Bulk Density | Volumetric Method | Mass of sample freely poured into a calibrated cylinder divided by its volume (ASTM D1895). |
