Abstract: A process of forming a sintered article includes heating a green portion of a tape of polycrystalline ceramic and/or minerals in organic binder at a binder removal zone to a temperature sufficient to pyrolyze the binder; horizontally conveying the portion of tape with organic binder removed from the binder removal zone to a sintering zone; and sintering polycrystalline ceramic and/or minerals of the portion of tape at the sintering zone, wherein the tape simultaneously extends through the removal and sintering zones.

Abstract: A waveguide includes a body of material having a width, a thickness, and a length, where the width is orthogonal to the thickness, and the length is orthogonal to the thickness and the width. The material includes polycrystalline ceramic that is transmissive such that the body is configured as a waveguide. The thickness is no more than 5 millimeters and at least 20 nanometers, the width is greater than or equal to the thickness, and the length is at least 100 times greater than the width. The body of material has a granular profile such that grains of the material protrude generally outward from a surface of the body with a height of at least 25 nanometers and no more than 100 micrometers relative to recessed portions of the surface of the body at boundaries between the grains.

Abstract: A system, process and related sintered article are provided. The process includes supporting a piece of inorganic material with a pressurized gas and sintering the piece of inorganic material while supported by the pressurized gas by heating the piece of inorganic material to a temperature at or above a sintering temperature of the inorganic material such that the inorganic material is at least partially sintered forming the sintered article. The inorganic material is not in contact with a solid support during sintering. The sintered article, such as a ceramic article, is thin, has high surface quality, and/or has large surface areas.

Abstract: Ceramic assembly can comprise a ceramic article comprising a thickness defined between a first major surface and a second major surface. The thickness can be about 100 micrometers or less. The ceramic assembly can comprise a polymer coating deposited over at least an outer peripheral portion of the first major surface of the ceramic article. The polymer coating can comprise a thickness of about 30 micrometers or less. An edge strength of the ceramic assembly can be greater than an edge strength of the ceramic article by about 50 MegaPascals or more. Methods of forming a ceramic assembly can comprise depositing a polymer coating on an outer peripheral portion of a first major surface of a ceramic article. Methods can further comprise curing the polymer coating.

Abstract: A manufacturing line includes a tape of green material that is directed through a furnace so that the furnace burns off organic binder material and then partially sinters the tape without the use of a setter board. Sintered articles resulting from the manufacturing line may be thin with relatively large surface areas; and, while substantially unpolished, have few sintering-induced surface defects. Tension may be applied to the partially sintered tape as it passes through a second furnace on the manufacturing line to shape resulting sintered articles.
