Other Technological Developments and Products

Other technological developments and products, using Kubota's technologies to produce specially-shaped titanic acid compounds and achieve high functionality, are as follows:

Porous titanic acid compounds "GTX"

Usually, potassium titanate has anisotropic crystal growth. Kubota Corporation has controlled anisotropy by adding a third component to successfully synthesize spherical porous sintered particles.

Plate-like calcium titanate "TXAX-CT"

Kubota Corporation has successfully synthesized plate-like calcium titanate with a large diameter and length by combining conventional solid reaction method with Kubota’s shape control and intercalation ionic exchange technologies.
