BESPA BT( Oxalate Method Barium Titanate )
Overview
BESPA( Oxalate Method Barium Titanate )
CAS No.12047-27-7
BESPA BT is barium titanate (BaTiO3) synthesized by oxalate method.
Barium titanate has been used traditionally as capacitor material because of its high dielectric characteristic. In particular, it has made great contributions in the improvement of electronic circuit performance through use in dielectric layer of multi-layer ceramics capacitor (MLCC).
Because of the shift towards smaller, higher capacity, and thinner MLCC, there is demand for smaller particle sizes of barium titanate as the main ingredient. We are polishing the manufacturing technology of barium titanate by oxalate method to lead development into the field of nano particles.
Also, barium titanate particles can be dispersed in polymer materials (such as resins and rubbers) as high dielectric constant fillers to modify the materials into highly dielectric materials. In order to meet these demands, we have a lineup of barium titanate with large particle sizes of 2μm and 14μm.
