Latest Patents

One of his key patents is titled "Method for producing barium titanium oxide single-crystal piece using containerless processing." This patent discloses a method for producing a barium titanium oxide single crystal piece with a specific structure through a containerless solidification process. The process involves preparing a material made of barium titanium oxide, levitating it within a furnace, melting it with a laser, and solidifying it while maintaining the levitated state. A notable embodiment of this method includes a spherical sample of BaTiO weighing about 20 mg, which undergoes rapid solidification and melting at a temperature gradient of approximately 700 K/sec. This process is repeated three times while the sample is levitated in an electrostatic levitation furnace at 4.5 atm of air atmosphere. The resulting transparent blue barium titanium oxide single crystal exhibits innovative dielectric characteristics, including a large relative permittivity of 100,000 or more at room temperature and low dielectric loss. Additionally, the crystal demonstrates excellent temperature stability, allowing for a gentle reduction in relative permittivity from room temperature to 70 K.
