Industrial Applications of Strontium oxide
| Industry | Application | Process |
|---|---|---|
| Electronics Industry | Additive in cathode ray tube (CRT) glass manufacturing to enhance brightness and stability | Cofused with raw materials such as silica sand and barium carbonate during CRT glass melting |
| Optical Materials | Component of specialty optical glasses to improve refractive index and dispersion properties | Cosmelted with other oxides (e.g., SiO₂, B₂O₃) in high-temperature furnaces |
| Ceramics Industry | Flux and stabilizer in glazes to reduce firing temperature and enhance surface gloss | Mixed as a powder with other metal oxides in ceramic glaze formulations, then applied and fired |
| Specialty Alloys | Raw material for strontium-based hydrogen storage alloys (e.g., precursors related to SrFe₁₂O₁₉) | Thermally treated with iron oxides via solid-state reaction or sol-gel processing |
| Chemical Reagents | Starting material for laboratory synthesis of other strontium compounds (e.g., strontium nitrate, strontium carbonate) | Reacted with corresponding acids (e.g., HNO₃) or salts (e.g., Na₂CO₃) via acid-base or double displacement reactions |
Manufacturing Quality Control of Strontium oxide
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Primary Component Content (SrO) | Atomic Absorption Spectroscopy (AAS) | The sample is dissolved and the absorbance of strontium is measured at a specific wavelength. The SrO content is quantified using a calibration curve. This method offers high sensitivity and simple operation. |
| Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) | After acid digestion, the sample is introduced into a high-temperature plasma where strontium is excited. Quantitative analysis is based on the intensity of characteristic emission lines. Suitable for simultaneous multi-element analysis with high precision. | |
| Titration Method (EDTA Complexometric Titration) | The sample is dissolved and titrated with EDTA standard solution at pH ~10 using EBT or calcon indicator to determine Sr²⁺. The SrO content is then calculated. Low cost and suitable for routine testing. | |
| Impurity Elements | Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | Capable of detecting various metallic impurities (e.g., Fe, Al, Ca, Mg) at sub-ppb levels. Extremely high sensitivity, ideal for impurity control in high-purity strontium oxide. |
| X-Ray Fluorescence Spectrometry (XRF) | Requires minimal sample preparation; samples are pressed into pellets or fused into glass beads before elemental analysis. Suitable for rapid screening of impurities, though less sensitive for light elements. | |
| Phase Composition | X-Ray Diffraction (XRD) | Analyzes the crystal structure of the sample to confirm whether it is pure SrO phase, and detect any unreacted SrCO₃ or other strontium compounds. Used for phase purity identification. |
| Loss on Ignition (LOI) | Gravimetric Method (Thermogravimetric Analysis) | The sample is heated to high temperature (e.g., 1000°C) until constant weight is achieved. The mass loss is used to calculate weight reduction due to moisture, carbonate decomposition, etc., reflecting sample stability. |
| Particle Size Distribution | Laser Diffraction Particle Size Analysis | Measures particle size distribution based on laser scattering principles. Important for controlling product uniformity and reactivity, significantly influencing application performance. |
| Chloride Ion Content | Ion Chromatography (IC) or Argentometric Method | Ion chromatography allows precise measurement of trace chloride ions; the argentometric method involves titration with silver nitrate, offering simple operation suitable for routine control. |
