Industrial Applications of Strontium titanate
| Industry | Application | Process |
|---|---|---|
| Electronics Industry | Component of piezoelectric ceramic materials for manufacturing multilayer ceramic capacitors (MLCCs) | High-temperature solid-state reaction: Titanium dioxide (TiO₂) and strontium carbonate (SrCO₃) are mixed in stoichiometric ratio, followed by ball milling, drying, and calcination at 1200–1400°C to produce strontium titanate (SrTiO₃) |
| Electronics Industry | Semiconductor substrate material for epitaxial growth of oxide thin films | Molecular beam epitaxy (MBE) or pulsed laser deposition (PLD): Strontium and titanium targets are evaporated and deposited onto single-crystal substrates under ultra-high vacuum to form SrTiO₃ thin films |
| Optics Industry | Additive in low-dispersion optical glass to improve refractive index and light transmittance | Fusion method: Strontium titanate powder is blended with silicates, borates, etc., melted at high temperature (>1500°C), and cooled to form optical glass |
| Sensors Industry | Sensing material in gas sensors for detection of oxygen, carbon monoxide, etc. | Sol-gel or hydrothermal synthesis: Nanoscale SrTiO₃ powder is prepared and sintered into porous ceramic structures for surface adsorption and conductance response |
| Solar Energy Industry | Electron transport layer (ETL) in perovskite solar cells | Solution spin-coating: A strontium titanate precursor solution (e.g., strontium acetylacetonate / titanium isopropoxide) is spin-coated onto FTO substrates and annealed to form a dense film |
| Catalysis Industry | Catalyst support or promoter catalyst for oxidation reactions | Co-precipitation: Strontium and titanium salts are precipitated under alkaline conditions, followed by washing, drying, and calcination to yield high-surface-area SrTiO₃ support |
Manufacturing Quality Control of Strontium titanate
| Inspection Item | Common Testing Methods | Method Overview |
|---|---|---|
| Phase Composition | X-ray Diffraction Analysis (XRD) | Compare the X-ray diffraction pattern with standard reference cards to confirm whether the sample is a pure perovskite-structured strontium titanate, and detect the presence of impurity phases (e.g., SrCO₃, TiO₂). |
| Chemical Composition | Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES) or Mass Spectrometry (ICP-MS) | Dissolve the sample and measure the contents of Sr and Ti to evaluate whether the elemental ratio conforms to the stoichiometric proportion (Sr:Ti = 1:1). |
| Purity | Differential Scanning Calorimetry-Thermogravimetric Analysis (DSC-TGA) | Analyze mass changes and thermal effects during heating to determine the presence of organic residues, moisture, or carbonate impurities. |
| Particle Size Distribution | Laser Particle Size Analysis (LPSA) | Measure the particle size distribution of powders using laser scattering principles to assess uniformity and suitability of the powder. |
| Specific Surface Area | Nitrogen Adsorption-Desorption Method (BET Method) | Calculate the specific surface area of the material from nitrogen adsorption isotherms, reflecting the dispersion and reactivity of the powder. |
| Microstructure Morphology | Scanning Electron Microscopy (SEM) | Observe particle morphology, size, agglomeration, and surface characteristics to assist in evaluating the effectiveness of the synthesis process. |
| Crystal Structure and Defects | Transmission Electron Microscopy (TEM) | High-resolution imaging enables observation of lattice fringes to analyze crystal integrity, lattice distortion, dislocations, and other microscopic structural features. |
| Impurity Elements (e.g., Fe, Ni, Cl⁻, etc.) | Atomic Absorption Spectroscopy (AAS) or Ion Chromatography (IC) | Detect metal or anionic impurities that may affect electrical properties, ensuring high purity requirements (particularly important for electronic ceramic applications). |
| Density | Archimedes' Water Displacement Method | Measure the bulk density of sintered samples to assess the degree of densification, indirectly reflecting material homogeneity and process stability. |
