Barium Titanate (BaTiO₃) Sputtering Targets

High-purity barium titanate (BaTiO₃) sputtering targets (≥99.9% purity) are indispensable for cutting-edge thin-film deposition 

technologies such as magnetron sputtering (PVD) and pulsed laser deposition (PLD). As a perovskite-structured multifunctional material, 

BaTiO₃ exhibits exceptional ferroelectric, dielectric, and piezoelectric properties, making it a cornerstone in advanced research and 

industrial innovation. Below are its key application domains tailored for academic and industrial thin-film laboratories:

1. Electronics & Semiconductor Devices

Ferroelectric Memory: BaTiO₃ thin films enable non-volatile memory devices (FeRAM) with ultrafast switching speeds 

and high polarization retention.

Multilayer Ceramic Capacitors (MLCCs): High dielectric constant (ε > 1,000) films for miniaturized, high-capacity energy 

storage components.

Lead-Free PTCR Thermistors: BaTiO₃-based ceramics with tunable Curie temperatures for overcurrent protection 

and temperature sensing applications.

2. Optoelectronics & Display Technology

Self-Powered UV Photodetectors: BaTiO₃-TiO₂ heterostructures enhance photoresponse and reduce dark currents in 

UV detectors, enabling integration into optical logic circuits.

Electro-Optic Modulators: Ferroelectric thin films for high-speed light modulation in LiDAR and telecommunication systems.

3. Energy & Environmental Catalysis

Photocatalytic Water Treatment: Pt-doped BaTiO₃ with oxygen vacancies degrades antibiotics (e.g., moxifloxacin) and 

simultaneously produces hydrogen (1,519 µmol·g⁻¹·h⁻¹) under visible light.

Perovskite Solar Cells: BaTiO₃ interfacial layers improve charge extraction and stability in hybrid photovoltaic devices.

4. Sensors & Functional Coatings

Gas Sensors: BaTiO₃-based films detect volatile organic compounds (VOCs) and NOₓ with high sensitivity due to surface redox activity.

Piezoelectric Sensors: Strain-responsive coatings for wearable health monitoring and industrial pressure sensing.

5. Fundamental Research & Emerging Technologies

Multiferroic Materials: Strain-engineered BaTiO₃ exhibits coexisting ferroelectricity and magnetism for spintronic and quantum computing research.

2D Heterostructures: Integration with graphene or MoS₂ to study interfacial charge transfer and polarization effects.
