Glass microspheres are microscopic spheres of glass manufactured for a wide variety of uses in thermal insulation coating, putty, plastic casting polyester, radome, synthetic foam, adhesives, printed circuit board substrate, bowling, fan blades, and caulking materials, emulsion explosives, golf, sealant, pipeline insulation materials, artificial marble, PVC, low density oil drilling, light cement etc. Glass microspheres are usually between 1 and 1000 micrometres in diameter, although the sizes can range from 100 nanometres to 5 millimetres in diameter. Microspheres are spherical particles that can be distinguished into two categories; solid or hollow. This paper presented a general overview of glass microspheres.

“…He describes a combination of a metal hydride and glass sphere hydrogen storage system, which should also have an increased volumetric storage density. So far, hydrogen storage densities of γ G = 2-17 wt% and γ V = 10-14 kg/m 3 have been experimentally realized with hollow glass microspheres, microcapsules, microballoons or microcavities [4,10,14,[17][18][19].

Summary Hydrogen‐pressurized hollow glass microspheres (HGMs) in combination with a hydride bear the potential of storing hydrogen in feasible amounts. Therefore, the approximately 20‐µm diameter spheres are heated up and pressurized with hydrogen at a pressure of 85 MPa, so hydrogen diffuses into the spheres. After the spheres are cooled down, hydrogen can be stored at room temperature without excessive security measures. To release the stored hydrogen, heat has to be applied again to reach temperatures of about 250 °C (523.15 K). To reach this temperature, it is suggested in this work to use an exothermal chemical reaction, which produces hydrogen as a by‐product. In this case, an NaBH4–water reaction will be discussed, which has to be initialized by a catalyst deployed on the HGMs. It will be shown that hydrogen storage densities of up to 20 wt% and 50 kg/m3 can be theoretically achieved with the proposed hydrogen storage system consisting of hydrogen‐pressurized HGMs and a hydride, that is, NaBH4. Volumetric storage density and other aspects, such as water management, temperature restriction, stoichiometric restriction and hydrogen diffusion through glass, will be discussed. Due to resulting high water vapour pressures, a pressure vessel will still be needed in the concept. This paper shall give an overview of theoretically achievable storage densities with the proposed system. Experiments were carried out regarding catalytic promoted hydrolysis with HGMs, and resulting storage densities were determined. These experiments show good agreement with theory. However, they will be addressed only briefly in the outlook of the paper because a detailed discussion would go beyond the scope of this work. Copyright © 2016 John Wiley & Sons, Ltd.

“…Nowadays, hollow glass microspheres represent a crucial component of lightweight multifunctional composite materials and are frequently used in aerospace [ 1 ], ships [ 2 , 3 ], flame retardant [ 4 , 5 ], dielectric materials [ 6 , 7 ], and hydrogen storage [ 8 , 9 ], thanks to their lightweight, low permittivity and low thermal conductivity [ 4 , 10 ]. Their low conductivity makes these materials highly functional in thermal insulation applications [ 5 , 11 , 12 , 13 ].…”

This study aims to assess the effect of hollow glass microspheres of different sizes derived from glass industry waste on the durability and thermal behavior of waterborne paint. The coatings were characterized by electron microscopy to investigate the distribution of the spheres and their influence on the layer morphology. The impact of the various glassy spheres on the mechanical feature of the coatings was assessed using the Buchholz hardness test and the Scrub abrasion test. The role of the spheres in altering the durability of the samples was analyzed by the salt spray exposure test and the electrochemical impedance spectroscopy measurements. Finally, a specific accelerated degradation test was carried out to explore the evolution of the thermal behavior of the composite coatings. Ultimately, this work revealed the pros and cons of using hollow glass spheres as a multifunctional paint filler, highlighting the size of the spheres as a key parameter. For example, spheres with adequate size (25–44 µm), totally embedded in the polymeric matrix, are able to reduce the thermal conductivity of the coating avoiding local heat accumulation phenomena.
