Abstract: PROBLEM TO BE SOLVED: To obtain a β-spodumene structure and further to provide a method for preparing the β-spodumene structure. SOLUTION: This method for preparing a β-spodumene structure comprises preparing a homogeneous plastic batch comprising an inorganic raw material, an organic binder and a vehicle, in which the inorganic raw material comprises about 75-95 wt.% mineral and about 5-25 wt.% glass. A green ware is formed out of the batch, and the green ware is fired to provide a structure substantially constituted of the β-spodumene, and having (0-800 deg.C) thermal expansion and >=4 Ksi strength.

Abstract: An athermal optical device and a method for producing the device, such as an athermal optical fiber reflective grating, are described. The athermal optical fiber reflective grating device comprises a negative expansion substrate, an optical fiber mounted on the substrate surface, and a grating defined in the optical fiber. The method for producing the athermal optical fiber reflective grating device comprises providing a negative expansion substrate, mounting an optical fiber with at least one reflective grating defined therein onto the substrate upper surface, and affixing the optical fiber to the substrate at at least two spaced apart locations.

Abstract: Ceramic matrix composite articles comprising A ceramic, glass ceramic or glass matrix and a fiber reinforcement phase disposed within the matrix consisting of amorphous or crystalline inorganic fibers, wherein there is provided, on or in close proximity to the surfaces of the inorganic fibers, a layer of sheet silicate crystals constituting a sheet silicate interface between the inorganic fibers and the ceramic, glass, or glass-ceramic matrix. Optionally, the composition of the matrix may be the same as the sheet silicate interface so that the matrix provides the sheet silicate layer.
