Actually, our company needs some special material
(Barium Titanate BaTiO3), preferrably in planar form (4" x 4" x 0.020" to 0.050")
as a substrate for some special eletcronic sensing device. Both monocrystalline and polycrystalline forms are suitable for this as well as smaller size if 4" square are not available.
If you have something in this direction please send me a quote for sample quantity.

What are Barium Titanate Crystal Substrates and Its Application?
Barium Titanate (BaTiO₃) Crystal Substrates
Barium Titanate (BaTiO₃) is a perovskite-structured ferroelectric material widely used in electronic and optical applications. It exhibits excellent dielectric, piezoelectric, and electro-optic properties, making it a valuable material for advanced electronic and photonic devices.
Key Properties of BaTiO₃ Crystal Substrates:
- Ferroelectricity: Exhibits spontaneous polarization, which can be switched by an external electric field.
- High Dielectric Constant: Ideal for capacitor applications and high-frequency electronics.
- Piezoelectric Effect: Useful for sensors and actuators.
- Electro-Optic Effect: Used in tunable optical devices.
- Good Thermal Stability: Suitable for high-temperature applications.
- Optical Transparency: Useful in optoelectronics.
Applications of BaTiO₃ Crystal Substrates
1. Electronic Devices
- Capacitors: BaTiO₃-based multilayer ceramic capacitors (MLCCs) are widely used in electronics due to their high dielectric constant.
- Dynamic Random Access Memory (DRAM): Used as a high-k dielectric material in memory cells.
2. Optoelectronic Applications
- Electro-Optic Modulators: BaTiO₃'s high electro-optic coefficient makes it ideal for modulating light in optical communication.
- Nonlinear Optics: Used in second harmonic generation (SHG) and frequency conversion applications.
3. Piezoelectric Sensors and Actuators
- Medical Ultrasound Transducers: Used in high-frequency ultrasound imaging due to its high piezoelectric response.
- Microelectromechanical Systems (MEMS): Applied in precision actuators, pressure sensors, and accelerometers.
4. Photonic and Quantum Computing
- Integrated Photonics: Can be used as a substrate for developing photonic integrated circuits (PICs).
- Quantum Devices: Investigated for use in quantum computing due to its unique polarization properties.
5. Thin-Film and Heterostructure Research
- Epitaxial Growth of Functional Oxides: BaTiO₃ substrates serve as a template for growing thin films of other ferroelectric and high-k dielectric materials.
- 2D Materials & Interface Engineering: Used in research involving interface effects with graphene, transition metal dichalcogenides (TMDs), and oxide semiconductors.
