Mo-Sci supplies highly specialized glass microspheres, powders, and ingots, often in quantities and compositions that are difficult to obtain anywhere else. Our dedication to specialty glass development has made us the supplier of choice for customers with the most demanding specifications, including several Fortune 500 companies.
Bioactive glasses have the ability to bond to soft and/or hard tissue and are biodegradable in the body. The release of ions and the formation of hydroxyapatite support the regeneration of bone tissue and can accelerate the healing process. These glasses are made from high purity (analytical and reagent grade) chemicals, keeping unwanted trace impurities to a minimum. Precious metal or high purity ceramic crucibles are used to melt these glasses in dedicated furnaces and they are processed in an environmentally controlled space.
Sealing glasses function as high-temperature sealant materials for solid oxide fuel cells (SOFCs) and other applications such as sodium-ion batteries.
Standard glass-ceramic seals crystallize and bond to seal components.
Viscous glass seals bond to metals and ceramics, but resist crystalization and operate in a viscous state at SOFC operating temperatures. Viscous seals reduce the risk of catastrophic seal failure through viscous healing of cracks if they form during thermal cycling.
Class IV Industrial Grade microspheres provide high quality glass beads at a more economical price point for such applications as filler materials and adhesive spacer. These microspheres are supplied with 85% true spheres and 80% or better sizing in the specific range.
Class V Engineering Grade microspheres provide precision sizing with a high spherical quality. These microspheres are supplied will 90% true spheres and 90% or greater sizing within the range.
Class VI Spacer Grade Glass microspheres are manufactured to provide highly accurate bondline spacing. These microspheres are supplied with greater than 90% true spheres and greater than 95% in the specified size range. Sizes range from 38µm±7% to 850µm±5%.
Porous silica glasses are resistant to acidic conditions and can be used for a variety of applications from chromatography, a carrier for release of liquids, an absorber for liquids (a.k.a. “thirsty glass”), and thermal barrier protection. Our porous silica is a >98% SiO2 and <2% B2O3 material with an open porosity of ~45% and a specific surface area of ≥250m2/g.
Porous wall hollow microspheres provide a porous shell for introduction or release of liquids. The porous shells have a microstructure similar to Vycor and are composed of open channels from the outer shell to the inner shell. Our porous wall hollow microspheres are ~98% porous with pore sizes ranging from 100Å to 3000Å and a shell thickness of ~1µm.
