Mechanical strength of a composite material is enhanced by a simple process. In a composite material comprising a resin or a rubber and an oxide glass, the resin or the rubber is dispersed in the oxide glass, or the oxide glass is dispersed in the resin or the rubber. The composite material has a function that the oxide glass is softened and fluidized by electromagnetic waves.

A solid state method of producing inorganic nanoparticles using glass is disclosed. The nanoparticles may not be formed until the glass is reacted with or degraded by contact with a fluid in vivo or in vitro.

A composition for the additive manufacture of three-dimensional objects is provided. The composition includes a sinterable frit, a protein binder, and an aqueous-based solvent.

A method includes impregnating a region of a glass sheet with a filler material in a liquid state. The glass sheet includes a plurality of glass soot particles. The filler material is solidified subsequent to the impregnating step to form a glass/filler composite region of the glass sheet.

An apparatus for making a composite article includes a monofilament feed track adapted to carry a spaced array of ceramic monofilament strands, a fiber yarn feed track adapted to carry a spaced array of fiber yarn tows impregnated with a plurality of glass particulates, a mandrel, and a heater assembly. The mandrel is adapted to wind together individual glass-impregnated fiber yarn strands and individual ceramic monofilament strands to form a dual-fiber weave. The heater assembly is adapted to heat at least the glass particulates such that pressure from the wound array of ceramic monofilaments is sufficient to consolidate the glass particulates and the dual-fiber weave into a dual-fiber ceramic matrix composite (CMC).

A glass composition, a macrocomposite, and methods of forming the macrocomposite including dispersing or immersing a metal in a glass. Preferably, the macrocomposite does not include an organic resin, an adhesive, or a polymer.

The disclosure relates to a Low Temperature Co-fired Ceramic (LTCC) substrate and a preparation method thereof, and in particular to a dielectric-constant-adjustable LTCC substrate and a preparation method thereof. The LTCC substrate of the disclosure includes the following components: glass, SiO.sub.2 and Al.sub.2O.sub.3, a weight percentage of the SiO.sub.2 in the LTCC substrate is 10% to 25%.

A process and a plant produce hollow microspheres made of glass. According to the process an aqueous suspension is prepared from starting materials containing glass powder and water glass, feedstock particles having a diameter between 5 μm and 300 μm, in particular between 5 μm and 100 μm, being produced from the suspension. The feedstock particles are mixed with a pulverulent release agent made of aluminum hydroxide in an intensive mixer. The mixture of feedstock particles and release agent is subsequently introduced into a firing chamber of a furnace. The feedstock particles expand in the firing chamber, at a firing temperature which exceeds the softening temperature of the glass powder, to form the hollow microspheres.

A method of manufacturing a polarizing glass sheet includes subjecting, while heating, a glass preform sheet containing metal halide particles to down-drawing, to thereby provide a glass member having stretched metal halide particles dispersed in an aligned manner in a glass matrix, and subjecting the glass member to reduction treatment to reduce the stretched metal halide particles, to thereby provide a polarizing glass sheet. A shape of the glass preform sheet during the down-drawing satisfies a relationship of the following expression:
L.sub.1/W.sub.1≥1.0
where L.sub.1 represents a length between a portion in which a width of the glass preform sheet has changed to 0.8 times an original width and a portion in which the width of the glass preform sheet has changed to 0.2 times the original width W.sub.0, and W.sub.1 represents a length equivalent to 0.5 times the original width W.sub.0 of the glass preform sheet.
