Ultrasonic Spray Coating Machine for Nano Barium Titanate

Ultrasonic Spray Coating Machine for Nano Barium Titanate

Nano barium titanate (tetragonal phase) is a high-performance perovskite-type ferroelectric nanomaterial. Using barium titanate as its core, it is precisely prepared to control the crystal structure to a tetragonal phase. It possesses excellent dielectric, piezoelectric, and ferroelectric properties, along with good thermal stability, making it an indispensable core material in high-end fields such as electronic components and precision sensing. Its appearance is a white or pale yellow ultrafine powder or uniformly dispersed liquid, with a purity exceeding 99%. The particle size distribution is uniform and can be customized according to requirements (typically 20-100nm). The tetragonal phase crystal structure is stable and can be prepared through sol-gel, hydrothermal, and solid-state reaction methods. It is suitable for various dispersion systems such as water-based and alcohol-based systems, exhibiting excellent stability and long-term storage without agglomeration or delamination. It perfectly meets the precision coating needs of various scenarios.

Although tetragonal barium titanate nanoparticles exhibit excellent performance and wide applications, their high surface energy, crystal form sensitivity, and tendency to agglomerate limit the effectiveness of traditional spray coating processes in achieving high-quality film formation. The high surface tension of barium titanate nanoparticles makes them inherently prone to agglomeration, forming hard aggregates. This not only disrupts their tetragonal crystal structure, preventing them from realizing their core advantages such as dielectric and piezoelectric properties, but also introduces defects like porosity, uneven thickness, and surface roughness into the coating. Furthermore, their fragile tetragonal crystal structure makes them susceptible to crystal breakage and lattice distortion due to the high-pressure impact and mechanical shearing forces of traditional pneumatic spraying and spin coating processes. This leads to significant performance degradation, and uneven atomization results in substantial material waste, failing to meet the stringent coating standards of high-end electronic components and precision sensors, thus severely limiting their large-scale application.

Cheersonic ultrasonic spray coating machines, specifically designed for the material characteristics of tetragonal barium titanate nanoparticles, offer a customized precision spray coating process that completely solves the various pain points of traditional processes. The equipment employs a 50-120kHz high-frequency ultrasonic atomization principle. Through a piezoelectric transducer, electrical energy is converted into high-frequency mechanical vibration, uniformly atomizing a nano-barium titanate dispersion into micron-sized fine droplets. The entire process involves low-pressure, gentle atomization, without high-pressure impact or mechanical shearing, achieving a “soft landing” of the droplets. This maximizes the preservation of the tetragonal crystal structure of the nano-barium titanate, preventing crystal breakage, lattice distortion, and particle agglomeration. Simultaneously, it efficiently disperses slightly agglomerated particles, ensuring uniform dispersion and precisely preserving its excellent dielectric, piezoelectric, and ferroelectric properties.

Compared to traditional spraying processes, Cheersonic ultrasonic spraying equipment offers significant advantages. The equipment boasts high atomization uniformity, with coating thickness uniformity consistently within a 5% deviation. It enables the preparation of nanoscale ultrathin continuous films, producing dense, pinhole-free, and crack-free coatings with strong adhesion. This fully leverages the core properties of tetragonal phase nano-barium titanate, meeting the stringent requirements of high-end products. The non-contact directional deposition spraying method achieves a nano-barium titanate utilization rate exceeding 90%, a significant improvement over traditional processes. This effectively reduces waste of high-end materials, controls production costs, and aligns with green production principles. The equipment is highly compatible, adaptable to tetragonal phase nano-barium titanate dispersions of varying particle sizes and concentrations, and suitable for diverse substrates such as silicon wafers, metals, ceramics, and flexible films. It enables both large-area uniform spraying and small-area precision spraying, meeting the needs of both laboratory research and industrial mass production.

In practical applications, nano-barium titanate films prepared by the Cheersonic ultrasonic spraying machine exhibit stable performance and excellent repeatability, making them widely applicable in various high-end fields. In the field of electronic components, it can be used in the coating of multilayer ceramic capacitors, piezoelectric sensors, and ferroelectric memory, leveraging its excellent dielectric and piezoelectric properties to improve the performance and stability of components. In the field of sensing, it can be used in the fabrication of precision piezoelectric sensors and pressure sensors, exhibiting high sensitivity to external signals and suitable for industrial inspection, medical equipment, and other scenarios. In the ceramics field, it can be used as a functional ceramic additive to improve the dielectric properties and mechanical strength of ceramics, suitable for the fabrication of high-end ceramic devices. In the new energy field, it can be used as an electrode coating for energy storage devices to optimize energy storage efficiency and contribute to the upgrading of the new energy industry.
