Abstract:
Plurality of nanocrystalline percent by volume crystalline ceramic oxide beads, wherein the nanocrystalline ceramic oxide beads have an average crystallite size up to 250 nm, wherein each bead collectively comprises, on a theoretical oxides basis, at least one of Al2O3, SiO2, TiO2, or ZrO2 at least 40 weight percent, and at least 1 weight percent of at least one of a transition metal oxide or at least one Bi2O3 or CeO2, based on the total weight of the nanocrystalline ceramic oxide beads, and are visibly dark and infrared transmissive. The beads are useful, for example, in pavement markings.
Abstract:
Plurality of granules comprising a ceramic core having an outer surface and a shell on and surrounding the core, wherein the shell comprises at least first concentric layers, wherein the first layer comprises first ceramic particles bound together with a first inorganic binder, wherein the first inorganic binder comprises reaction product of at least alkali silicate and hardener, wherein the shell of each granule collectively has a volume of at least 40 volume percent, based on the total volume of the respective granule, and wherein the granules have a minimum Total Solar Reflectance of at least 0.7. The granules are useful, for example, as roofing granules.
Abstract:
Conductive particles, articles including such particles, and methods of making such conductive particles, are provided; wherein the conductive particles include: a core particle including at least one of a glass, a glass-ceramic, or a metal; surface particles adhered to the core particle; and a metal coating disposed on at least a portion of the core and surface particles; wherein the core particle is larger than the surface particles.
Abstract:
A method for forming an inorganic or hybrid organic/inorganic layer on a substrate, which method comprises vaporizing a metal alkoxide, condensing the metal alkoxide to form a layer atop the substrate, and contacting the condensed metal alkoxide layer with water to cure the layer is disclosed.
Abstract:
