Hollow glass microspheres as measured by a gas pycnometer

"Average density" is the quotient obtained by dividing the mass of a sample of hollow glass microspheres by the true volume of that mass of hollow glass microspheres as measured by a gas pycnometer. "True volume" is the aggregate total volume of the glass bubbles (not the bulk volume); "glass" refers to all synthetic amorphous inorganic solids or melts that can be used to form amorphous solids, where the raw materials used to form such glass includes various oxides and minerals; "HOLLOW GLASS MICROSPHERES POWDER" refers to predominantly mono-cellular hollow glass microspheres; "mono-cellular" means that a given microsphere is defined by only one outer wall, with no additional walls, partial spheres or concentric spheres, or the like present in the microsphere; "natural glassy mineral" refers to an amorphous inorganic solid of natural, i.e., volcanic origins such as perlite, obsidian, or basalt; "recycled glass" refers to materials formed using glass as the raw material; and "softening" of glass refers to the Littleton softening point which is defined as the temperature where the glass has a viscosity of 106 6 Pa-s. Useful methods of making hollow glass microspheres are described herein by illustration and example. Repeated use of reference characters in the specification and drawings is intended to represent the same or analogous features or elements of the disclosure. It should be understood that numerous other modifications and embodiments can be devised by those skilled in the art, which fall within the scope and spirit of the principles of the disclosure. Figures may not be drawn to scale.
