    摘要: A uniform suspension of ceramic powder and method for making the same. The suspension is prepared by mixing finely divided ceramic powder in an aqueous carrier fluid, combining with a dispersing agent, and alternatively, an organic binder when forming a slip. The ceramic powder has an average particle size of about 0.5 micron or less and is present in the suspension in a loading of up to 30% by volume of the total solids in suspension. A passivating agent is present in the carrier fluid in an amount of 0.5 to 5% by weight of the ceramic powder present for suspension and slip respectively. After the addition of a dispersant, the suspension has a Bingham yield point of less than 230 dynes/cm2 and an apparent viscosity of less than 3000 cps. A green layer produced from the slip exhibits a pore size of less than 0.5 micron.

    摘要: A method for creating a patterned thin film of a high surface energy material on a substrate comprising the steps of creating a photomask pattern on the substrate using photolithography, providing an oppositely charged surface on the substrate and photomask, if such does not exist, from that of particles of the high surface energy material, removing the photomask and exposing the substrate to an aqueous colloidal suspension of particles composed of the high surface energy material to adsorb seed particles onto the surface of the substrate, or removing the photomask after adsorbing seed particles to the surface, and then depositing a uniform thin film of the high surface energy material by chemical vapor deposition onto the seeded substrate.

    摘要: A method is provided for improving the scratch or surface wear resistance of substrates by embedding discrete, hard particles within the surface layer of the substrate. Discrete, hard particles are applied to the substrate surface and then embedded within and bonded to the surface layer of the substrate by softening the substrate surface layer by either thermal or solvent means. Suitable substrate materials include thermoplastics, thermoset plastics, polymers, glass, soft metals, and composites. Suitable hard particles include diamond, silicon dioxide, aluminum oxide, cubic boron nitride, boron carbide, silicon carbide, silicon nitride, tantalum carbide, titanium carbide, titanium nitride, tungsten carbide, and zirconia alloys containing at least one phase stabilization additive selected from the group yttrium, hafnium, calcium, magnesium, and cesium. Scratch resistant substrates or articles having discrete, hard particles embedded within the surface layer of the substrate or article are also provided. These substrates or articles essentially have the surface wear characteristics of the hard particles or material embedded within the surface layer. Thus, it is possible to prepare plastic materials or articles having significantly improved scratch or surface wear resistance without significantly increasing the weight or external dimensions of the plastic materials or articles.

    摘要: The present invention relates to a method for forming a calcium-based carrier particle consisting of the calcium-based material, an active, with or without a surface modification, a stabilizing agent, and the related composition. The calcium-based particle is illustrated by the general formula Cax(PO4)y(OH)zR and may also include a silica or silica oxide substituent. R is an active or actives such as an organic or inorganic molecule that includes markers, amines, thiols, epoxies, organosilicones, organosilanes, sulfates, and water soluble agents and, as needed, a surface modification, S, which may be either organic or inorganic. A stabilizing agent may be necessary to maintain dispersion of the particles in aqueous media. Examples of a surface modifying material and stabilizing agents are inorganic salts of aluminum and boron or organic materials such as organosilanes or low molecular weight polymers. As such, the particle can be used in a variety of applications including any of a variety of high temperature, at acidic, neutral, or basic pH, or pressure environments. The carrier particles have applications as diverse as papermaking, water treatment, chemical tracing, personal care, microbiological control, oil recovery, delivery of polymers, for example.

The silica-based particle is illustrated by the formula (SiO2)x(OH)yRzSt, whereby R is an active or actives such as an organic or inorganic molecule that includes markers, amines, thiols, epoxies, organosilicones, organosilanes, and water soluble agents and, optionally, a surface modifier, S, which may be either organic, polymeric, or inorganic. Examples of a surface modifying material are inorganic salts of aluminum and boron or organic materials such as organosilanes or low molecular weight polymers. As such, the particle can be used in a variety of applications including any of a variety of high temperature, at acidic, neutral, or basic pH, or pressure environments. The composites have applications as diverse as papermaking, water treatment, chemical tracing, personal care, microbiological control, and delivery of polymers, for example. With regard to papermaking, the particle provides retention and drainage performance while delivering whitener, or OBA, other functional additives and serves an additive tracker.
