AI Technical Summary
Technical Problem
Existing inorganic fillers for high-frequency electronic components fail to simultaneously adjust relative permittivity and achieve a low dielectric loss tangent.
Method used
Titanium oxide with specific properties, including an L* value of 90 or more, a weight loss rate of 0.15% or less, and a dielectric loss tangent of 0.01 or less at 1 GHz, is used to adjust relative permittivity and reduce dielectric loss tangent.
Benefits of technology
The titanium oxide material allows for the adjustment of relative permittivity and achieves a low dielectric loss tangent, making it suitable for use as an inorganic filler in high-frequency equipment.
