Solid borosilicate glass microspheres are available in a large variety of particle size ranges from 10um to 6150um. Microspheres are supplied as a dry powder.

Particles in Size Range: >90% Sphericity: >90% Density: 7.7-7.9g/cc Vickers Hardness: ~200HV

The spheres are offered in dry powder form with the following coating options: Uncoated - no surface treatment Silane Coating (S2) - for improved dispersion in aqueous systems (~76 degree contact angle) Fluorochemical Coating (F35) - NEW FORMULA - for improved hydrophobicity to bring the spheres to the surface in solvent based systems Fluorochemical Coating (F1) - RETIRED FORMULA - for improved hydrophobicity to bring the spheres to the surface in solvent based systems Guidelines for Using...

The small size and spherical shape of the particles allow the powder to spread easily on most surfaces, creating a thin layer of powder, invisible to the naked eye under daylight illumination. When illuminated with 365nm UV light or black light, the powder acquires highly visible yellow-green fluorescent color, which is clearly distinguishable from the background. In this way, flesh-tone fluorescent microspheres are used as a reliable engineered contaminant simulation and verification...

Blue polymer spheres with specific gravity of 1.00g/cc are designed to match the density of water for optimal suspension of particles, enabling visualization and characterization of fluid flow for process modeling, optimization, and testing the capability of devices to withstand particulate matter in the fluid stream of the aqueous solution. It is critical that the density of polymer spheres is matched as close as possible to the density of water at the correct temperature. If there is a...

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,...

Physical Characteristics: Coating: Fully Aluminum Coated (~500nm thickness) Core: Solid Barium Titanate Glass Spheres Density: ~4.2g/cc Appearance: Grey powder

Yttria-stabilized zirconia microspheres and spheres (ZrO2 / Y2O3) are supplied as a dry powder. With operating temperatures up to 1000°C, a melting point of ~2700°C, and density of ~6g/cc, these solid ceramic spheres and microspheres demonstrate high impact resistance and very high strength and toughness, giving these ceramic beads superior wear tolerance. In addition, the material is chemically stable resulting in excellent corrosion resistance and unmatched durability at high temperatures...
