A thin film is provided that primarily comprises titanium oxide and includes Ti, Ag and O. The thin film contains 29.6 at % or more and 34.0 at % or less of Ti, 0.003 at % or more and 7.4 at % or less of Ag, and oxygen as the remainder thereof and has a ratio of oxygen to metals, O/(2Ti+0.5Ag), of 0.97 or more. The thin film has a high refractive index and a low extinction coefficient. In addition, the thin film has superior transmittance, minimally deteriorates in reflectance, and is useful as an interference film or a protective film for an optical information recording medium. The film may also be applied to a glass substrate to provide a heat reflective film, an antireflective film, or an interference filter. A method of producing the thin film is also disclosed.

The present disclosure provides a powder material that makes it possible to achieve higher flowability than before and to increase the crushing strength of particles. The powder material of the present disclosure has a dendritic structure 1. The dendritic structure 1 has a cemented carbide composition or a cermet composition.

The present disclosure generally relates to metallic powders for use in multilayer ceramic capacitors, to multilayer ceramic capacitors containing same and to methods of manufacturing such powders and capacitors. The disclosure addresses the problem of having better controlled smaller particle size distribution, with minimal contaminant contents which can be implemented at an industrial scale.

A system may include an energy delivery device and a computing device. The computing device may be configured to: control the energy delivery device to deliver energy to an abrasive coating, wherein the abrasive coating comprises a metal matrix and abrasive particles at least partially encapsulated by the metal matrix; and control the energy delivery device to scan the energy across a surface of the abrasive coating and form a series of softened or melted portions of the metal matrix.

Ceramic-metallic composites are disclosed along with the equipment and processes for their manufacture. The present invention improves the densities of these composites by eliminating porosity through the use of a unique furnace system that applies vacuum and positive gas pressure during specific stages of processing. In the fabrication of Al.sub.2O.sub.3—Al composites, each process commences with a preform initially composed of at least 5% by weight silicon dioxide, and the finished product includes aluminum oxide and aluminum, and possibly other substances.
