Abstract: A device includes a ceramic substrate formed of a first material, a polishable layer formed of a different material, and an interface between the ceramic substrate and the polishable layer. The interface is formed by infiltration of molten elemental silicon, and bonds the ceramic substrate and the polishable layer together. The device may include an optical device such as, for example, mirror or a beam dump. A method of making a device from a green-state structure and a polishable layer is also disclosed. The method includes infiltrating elemental silicon into and through the green-state structure, to form a substrate of a multi-phase ceramic material from the green-state structure, and to reactively bond the substrate and the polishable layer together.

Abstract: Various embodiments of the present invention are directed towards a system and method relating to depositing vapor in a sample. For example, a device includes a vapor source chamber configured to contain a vapor source material to generate vapor. An activation chamber is configured to contain a sample. The activation chamber is in fluid communication with the vapor source chamber to receive the vapor. A permeable separator divides the vapor source chamber and the activation chamber, and isolates the sample in the activation chamber while allowing vapor to pass between the vapor source chamber and the activation chamber. The device is sealable and configured to apply vacuum to the vapor and sample, to cause deposition of the vapor into the pumice stone samples.

Abstract: A process for conducting vapor phase deposition is disclosed. The process separates a series of reactions through a sequence of reaction reservoirs. The reactor includes a reactive precursor reservoir beneath a powder reservoir separated by valve means. A reactive precursor is charged into the reactive precursor reservoir and a powder is charged into the powder reservoir. The pressures are adjusted so that the pressure in the reactive precursor reservoir is higher than that of the powder reservoir. The valve means is opened, and the vapor phase reactant fluidized the powder and coats its surface. The powder falls into the reactive precursor reservoir. The apparatus permits vapor phase deposition processes to be performed semi-continuously.
