Coating: Half-shell Aluminum Coating
Core: Solid, Barium Titanate Glass
Specific Gravity: 4.49 +/- 0.01
Index of Refraction: 1.90 – 1.92
Mean Diameter: 40 - 50 microns
Maximum Diameter: 90 - 100 microns
Appearance & Odor: Grey powder, 55 – 65 on Gardner Scale
P2453BTA are solid, barium
titanate glass microspheres with a 40 - 50 micron mean diameter, a tight
distribution, and a top size of 100 microns that have been
hemispherically coated with a thin aluminum shell. In bulk, they appear
to be a grey powder. Under a microscope, each individual microparticle
can be seen to be a half coated sphere. Produced under strict quality
controls, these spheres are made from a barium titanate glass that has a
refractive index of 1.91, a specific gravity of 4.49, moh hardness
higher than steel, a crush point of 30,000 psi and a degree of roundness
in excess of 80%.
Optional Coatings Available at Extra Charge (Silane is stock, Fluorochemical adds 5-10 business days):
- Fluorochemical - Improved hydrophobicity to aide in bringing the spheres to the surface ($10)
- Silane - Improved dispersion ($10)
