A method of manufacturing a lithium ion conductive glass ceramic, includes a step of forming granules using a material including an SiO.sub.2 source, a ZrO.sub.2 source, a P.sub.2O.sub.5 source and an Na.sub.2O source; a step of obtaining a powder including a glass ceramic by passing the granules under a heated gas phase atmosphere to melt the granules and solidifying the melted granules; a step of obtaining a target object including a glass ceramic by performing a heat treatment on the powder to precipitate crystals; and a step of obtaining a lithium ion conductive glass ceramic by performing an ion-exchange process on the target object in molten salt including lithium ions.

A method of manufacture of a powder comprising, or consisting essentially of, microspheres, the method comprising: providing a feed powder; and applying at least one spheroidisation flame to the powder. The powder may be suitable for use in medical and/or non-medical applications.

Methods, systems and apparatus for producing continuous basalt fibers, microfibers, and microspheres from high temperature melts are disclosed. A cold crucible induction furnace is used to super heat crushed basalt rock to form a melt. The melt is cooled prior to forming a fiber. The fiber produced from the superheated melt possesses superior properties not found with conventional basalt fibers produced in gas furnaces. In some implementations, the superheated melt is spun into continuous basalt fibers. In some implementations, the superheated melt is blown into microfibers and microspheres.

To provide transparent solid spheres with high refractive index and large particle size. The transparent solid spheres of one aspect of the present disclosure include barium oxide, zirconium dioxide, and titanium dioxide on a theoretical oxide basis, and has a refractive index of at least 2.0 and a particle size of 600 micrometers or greater.

Provided is a filler powder that has a lower coefficient of thermal expansion than silica powder and can provide a resin composition having an excellent light transmittance. The filler powder is made of a crystallized glass with β-quartz solid solution and/or β-eucryptite precipitated therein, wherein a ratio D90/D10 between a 10% cumulative particle diameter (D10) and a 90% cumulative particle diameter (D90) both obtained by measuring a particle size distribution of the filler powder by a laser diffraction and scattering method is 20 or less.

Methods for making articles comprising crystalline material. Exemplary articles made by a method described herein include electronics enclosure (e.g., a watch case, cellular phone case, or a tablet case).

The glass contains a Ti component in a glass composition, in which a Ti.sup.3+ ion content is 80 ppm or less.
