Methods of melt spinning to make amorphous and ceramic materials.

Method of making amorphous and ceramics via melt spinning

Method for making ceramic particles. Embodiments of ceramic particles made according to the present invention can be are particularly useful as abrasive particles.

Methods of making ceramic particles

Ceramic fibers comprising glass, and composites comprising such fibers. The glass comprises at least 35 percent by weight AlO, based on the total metal oxide content of the glass, a first metal oxide other than AlO, and a second, different metal oxide other than AlO. The glass contains not more than 10 percent by weight collectively AsO, BO, GeO, PO, SiO, TeO, and VO, based on the total weight of the glass. The first and the second metal oxides are each selected from the group consisting of YO, REO, MgO, TiO, CrO, CuO, NiO, FeO, ZrO, HfOand complex metal oxides thereof. At least a portion of the glass may be converted to crystals.

AlO&#x2014;LaO&#x2014;YO&#x2014;MgO ceramics (including glasses, crystalline ceramics, and glass-ceramics) and methods of making the same. Ceramics according to the present invention can be made, formed as, or converted into glass beads, articles (e.g., plates), fibers, particles, and thin coatings. The particles and fibers are useful, for example, as thermal insulation, filler, or reinforcing material in composites (e.g., ceramic, metal, or polymeric matrix composites). The thin coatings can be useful, for example, as protective coatings in applications involving wear, as well as for thermal management. Some embodiments of ceramic particles according to the present invention can be are particularly useful as abrasive particles.

[object Object]

A powder feeding assembly for feeding a flame-melting device is disclosed. The powder feeding assembly includes a powder holding chamber with a screening member and a brush assembly disposed therein. The brush assembly includes at least one bristle element having a distal and a proximal end. The distal end is disposed proximate to the screening member. Powder held in the powder holding chamber is urged through one or more openings in the screening member by rotating the brush assembly. The powder is then delivered to an input section of the flame-melting device for processing.
