	Methods for producing hollow microspheres made from dispersed particle compositions - Patent 5225123
		The diameter and wall thickness of the hollow microspheres are determined primarily by the geometry of the nozzle components and by the viscosity of the dispersed particle composition, the blowing gas pressure, and where used the linear velocity of the transverse jet entraining fluid.
		The porosity and degree of intercommunication of the voids in the microspheres walls is determined primarily by the volume percent solid particles in the dispersed particle composition and the degree of sintering.
		Alternatively, microspheres may be treated to have the interconnecting voids filled and sealed with a dispersion of colloidal size particles that have a lower melting temperature than the dispersed particles in the hollow porous microspheres and the dispersion of colloidal size particles, then heated and fused to seal the interconnecting voids.

	Fibreglass - WOI Encyclopedia Italia
		Glass fiber is formed when thin strands of silica based or other formulation glass is extruded into many fibers with small diameters suitable for textile processing.
		Glass is unlike other polymers in that, even as a fiber, it has little crystalline structure (see amorphous solid).
		One definition of glass is "an inorganic substance in a condition which is continuous with, and analogous to the liquid state of that substance, but which, as a result of a reversible change in viscosity during cooling, has attained so high a degree of viscosity as to be for all practical purposes rigid." (Loewenstein, 4)

	Glass microsphere - Wikipedia, the free encyclopedia
		Glass microspheres are spheres of glass technically manufactured with a diameter in the micrometer range (from 1 to 1000 (microns))[1], although the term is also used for a wider range of 100 nanometres to 5 millimetres.
		Hollow glass microspheres, sometimes termed microballoons, have diameters ranging from 10 to 300 micrometers (microns)[2].
		Glass microspheres can be made by heating tiny droplets of dissolved water glass in a process known as ultrasonic spray pyrolysis, and properties can be improved somewhat by using an acid treatment to remove some of the sodium [4].

		This amount of microsphere material has been found to be between 0.5 and 0.75 but preferably about 0.75 pound of glass microspheres to one gallon of paint in the final formulation.
		The microspheres described in the preceding Table, in a ratio of 0.75 pounds per gallon of paint, are then added and agitation is continued at about 1500 RPM until the microspheres are completely and uniformly dispersed.

	Photo-enhanced Hydrogen Diffusion Through Glass Microspheres (Site not responding. Last check: 2007-11-03)
		Storage of hydrogen as a gas encased in hollow glass microspheres can be carried out in a manner which allows rapid release of hydrogen by photo-enhanced diffusion to meet the demands of fuel cells and other devices using hydrogen as a fuel.
		Application of this phenomenon to glass microspheres for storage of hydrogen can provide the enabling technology for replacement of traditional methods for storing and transporting hydrogen in high pressure containers or at cryogenic temperatures with lighter, cheaper, safer technology.

	Fiberglass Summary
		The first involves forming glass into marbles that are examined for impurities, then melted down; the liquified glass runs through tiny holes at the bottom of the furnace and is caught by a spinning drum that winds the strands on a bobbin while simultaneously pulling them into even finer fibers.
		In the third process, bulk fiberglass (fiberglass wool) is produced by melting the raw materials in a furnace and allowing the liquified glass to flow through tiny holes at the bottom; high-pressure steam jets catch the resulting strands and force them into fibers 8 to 15 inches (20 to 38 cm) long.
		The first type of glass used for fiber was soda-lime glass or A glass.

	Miniature Optoelectronic Oscillators Based on Microspheres
		In the proposed OEOs as in the OEOs of the preceding article, transparent (e.g., glass) microspheres that exhibit "whispering-gallery" electromagnetic modes at the laser wavelengths of the oscillators would be utilized as high-Q (where Q is the resonance quality factor and is the measure of energy storage time) resonator/delay elements in the oscillator feedback loops.
		In a microsphere, propagation in a long fiber is replaced by equivalent circulation of light by total internal reflection in "whispering-gallery" modes.
		In one operational scenario, light from the output of a phase modulator would be coupled into the microsphere to excite two modes, corresponding to a carrier signal and a sideband; it would be possible to do this because deviations from perfect sphericity would create modes with a frequency difference falling in the microwave range.

		In this work, such reinforcing materia ls, e.g., continuous and short E-glass fibers and glass microspheres, were incorporated in the photolithography process to develop a novel technique for the manufacturing of composite materials.
		Composite samples consisting of a photosensitive acrylate resin as the matrix and glass fibers as the reinforcement were prepared in the stereolithography apparatus to demonstrate the feasibility of the process.
		It was then used to demonstrate the feasibility of incorporating short glass fibers and hollow glass microspheres in the resin.

	Glass Microspheres Used In Explosives To Track Terrorists - New Technology
		Researchers at the University of Missouri-Rolla are using nano-sized glass microspheres to trace explosives back to their manufacturers and help law enforcement authorities thwart terrorists.
		Glass was chosen as it will not cause the explosive to detonate prematurely, nor will it more dangerous but also because they are already deliberately added to explosives to improve performance.
		The microspheres are then detected using a variety of methods depending on what was added to the spheres when they were formed.
