A glazing includes a glass substrate on which is deposited a coating including at least one layer, the layer being formed from a material including metal nanoparticles dispersed in an inorganic matrix of an oxide, in which the metal nanoparticles are made of a metal chosen from the group formed by silver, gold, platinum, copper and nickel or of an alloy formed from at least two of these metals, in which the matrix including an oxide of at least one element chosen from the group of titanium, silicon and zirconium and in which the atomic ratio M/Me in the material is less than 1.5, M representing all atoms of the elements of the group of titanium, silicon and zirconium present in the layer and Me representing all of the atoms of the metals of the group formed by silver, gold, platinum, copper and nickel present in the layer.

The present disclosure provides a method for coating a composite structure comprising the steps of applying a first slurry of a first phosphate glass composition on an outer surface of the composite structure. The first slurry comprises a first additive including at least one of molybdenum disulfide or tungsten disulfide. The method may further include heating the composite structure to a temperature sufficient to form a base layer adhered to the composite structure.

It is an object to provide a method for producing a member for a molten metal bath which is less likely to form minute cracks and pores in a pores-sealing coating film, and to provide a method for producing a member for a molten metal bath which can restrain adhesion of an alloy such as dross. The method for producing a member for a molten metal bath is characterized by applying or spraying, to a cermet thermal spray coating film formed on a base material or an oxide-based ceramic thermal spray coating film formed on a base material, a mixed solution obtained by adding aluminum dihydrogen phosphate and inorganic particles having a layered hexagonal crystal structure to a silica sol solution as a solution for sealing pores of the thermal spray coating film, and firing the mixed solution which is applied or sprayed to the thermal spray coating film.

A microfabrication method is provided with which it is possible to easily form a fine periodic structure on a surface of any substrate. A glass precursor is applied to a substrate, and the glass precursor is irradiated with short-pulse laser light. By the irradiation with short-pulse laser light, the glass precursor is activated to undergo a thermal reaction, and a fine periodic structure can be easily formed on the surface. Furthermore, by oxidizing the substrate on which the fine periodic structure has been formed, the hue of the surface can be improved while maintaining the fine periodic structure.

A transparent glass or ceramic or glass-ceramic substrate, coated with a functional layer or with a stack of at least two functional layers, the functional layer or at least one of the functional layers of the stack being porous and made of an inorganic material M1, wherein the or at least one of the porous functional layer(s) of inorganic material M1 has, at the surface of at least one portion of the pores thereof, at least one inorganic material M2 different from M1.

An oxidation protection system disposed on a substrate is provided, which may comprise a base layer comprising a first pre-slurry composition comprising a first phosphate glass composition, and/or a sealing layer comprising a second pre-slurry composition comprising a second phosphate glass composition and a strengthening compound comprising boron nitride, a metal oxide, and/or silicon carbide.

A composite silica glass made light diffusion member includes a dense silica glass, and a porous silica glass which has been layered on the surface of the dense silica glass.

The spherical silica glasses have an average diameter of 30 to 100 μm. An average value of a specific arithmetic average roughness Ra in each of the spherical silica glass exposed on an outer surface of the porous silica glass is 0.8 to 4.0 nm.

A semi-transparent coating material for coating glass or glass ceramics includes at least one sol-gel hybrid-polymer coating system having a hybrid-polymer or inorganic sol-gel-based matrix, and nanoparticles and nanoscale pigments and/or dyes are added to the hybrid-polymer or inorganic sol-gel-based matrix.
