Monodisperse Silica Nanospheres and Microspheres – Dry Powder
Silica nanoparticles and nanospheres are now available in distributions of less than 10% CV in the sizes of 0.25 micron, 0.5micron, 0.75 micron, 1.0 micron, 4 micron and 8 micron.
Microbeads for Fish Egg Simulation: Dispersion and Recruitment
Scientists who study fish require artificial micro-particles to simulate fish eggs and their behavior in water. In order to accurately simulate the fish eggs it is important to use particles of the proper size and buoyancy/density. Particles with accurate size ranges and densities are now available.
Microspheres as Bond Line Spacers in Epoxies
Spacer Grade Glass Microspheres are presently used in gas plasma displays, automotive mirrors, electronic displays, flip chip technology, filters, sporting goods equipment, calibration standards and transformer manufacturing. Every day engineers are finding new and innovative uses for bond line spacers.
High Density Glass Microspheres
Barium Titanate Glass microspheres are high density solid glass spheres. At a Density of 4.5g/cc these solid glass spheres can be used for many scientific applications where high density and optical clarity is needed. In addition to high density they also offer an index of refraction of more than 1.9.
BioCompatability of Metal Coated Spheres
For those scientists who are looking to use silver coated materials such as silver coated microspheres in biomedical applications, it is important to understand whether they are bio-compatable. A selection of abstracts and article references related to the biocompatability of silver follow:
High Index of Refraction Retroreflective Glass Microspheres
Barium Titanate Glass Microspheres are excellent for use as a functional retro reflective additive to paints and coatings. Spheres with sizes of about 50 micron (~0.002 inches) mean diameter provide a small enough size for most coatings while offering a large enough size to reflective a significant amount of light. Barium Titanate Glass Spheres are offered…
Patent Review: Process for forming hollow glass spheres up to 5mm
A process for forming hollow glass micro-spheres with walls of controllably variable thickness in a size range of 50 to 5,000 microns, embodying (1) preparation of a water slurry of finely particulated, high temperature and low temperature glass formers; (2) prilling the slurry in a vertical spray drying tower; (3) separating and supporting the individual prilled feed material; (4)…
Advantages of Borosilicate Glass Microspheres in 0.03mm to 0.2mm sizing
Borosilicate glass offers advantages over standard soda lime glass microbeads.
- Roundness is >90% (Soda lime >85%)
- Density is the lowest of most glasses at 2.2g/cc (Soda Lime 2.5g/cc)
- Very low thermal expansion coefficient 32×10-7/?C (for 30-300?C) (Soda Lime: 90×10-7/?C)
The high roundness, and low thermal expansion make…
