Barium Titanate Solid Glass Microspheres 4.1-4.4g/cc - 5um to 1000um (1mm)
Description
Barium Titanate solid glass microspheres are available in a large variety of particle size ranges starting at 5um to 1000um (1mm).
Microspheres are supplied as a yellowish dry powder.
Classified grades have narrower particle size ranges (e.g. 27-32um).
Bulk grades have wider size ranges and are more economical (e.g. 300-1000um).
Each product description below indicates density and refractive index.
Specifications
Barium Titanate glass spheres offer a higher Refractive Index (n) than most other glass formulations.
Depending on the grade of material, reflecting index of Barium Titanate glass is between 1.9 to 2.2 compared to n=~1.5 of Soda Lime and Borosilicate glasses.
Barium Titanate glass microspheres will reflect back more light directly to the viewer, which is beneficial for applications where retroreflectivity is desired, such as motion tracking targets in medical devices, endoscopy, micro-optics, defense and microscopy.
Please note that this material is a unique optical glass formulation based on a large percentage of Barium Oxide (BaO) and Titanium Oxide (TiO2).
Barium Titanate glass does not have the dielectric properties of Barium Titanate powder.
