    摘要： A method of treating a surface of a stacked aluminum alloy ingot during a heating process. Spacer blocks are positioned adjacent aluminum alloy ingots to form a stack, wherein the spacer block has a support surface contacting a contact surface of the aluminum alloy ingot, and at least one of the support surface and the contact surface include a fluorine containing material. The stack is heated to at least a temperature at which the fluorine containing material decomposes or vaporizes such that a layer of a fluorinated oxide compound is formed at the interfaces between the ingots and the spacer blocks.

    摘要： A treated permeable inorganic membrane is disclosed comprising a permeable inorganic membrane capable of reacting with an organic acid. The treated membrane has good chemical stability over a pH range of from 1 to 14, is capable of controlling the flux through the membrane, has altered internal and external wetting properties of the membrane surface, and has controlled pore size due to the presence of a monomolecular layer of an organic acid material chemically bonded to the surface of the inorganic membrane. The monomolecular layer of organic acid material is formed on the membrane surface by contacting the membrane with an organic acid reactant selected from the class consisting of phosphonic acid having the formula RPO(OH).sub.2 ; phosphinic acid having the formula RR'PO(OH); monocarboxylic acids having the formula RCOOH; dicarboxylic acids having the formula R"(COOH).sub.2 ; boronic acid having the formula RB(OH).sub.2 ; and one or more precursors of the foregoing acids which decompose to form the acid functionality; where R comprises a 1-30 carbon-containing group, R' comprises hydrogen or a 1-30 carbon-containing group, and R" comprises a 2-30 carbon-containing group. Excess organic acid reactant not bonded to the underlying membrane surface is removed to ensure formation of said monomolecular layer of said organic acid material on the surfaces of said permeable inorganic membrane.

    摘要： An active material is disclosed comprising metal oxide/hydroxide particles having chemically bonded to reactive sites on a surface thereof, a monolayer of a phosphorous-containing organic material comprised of a phosphorous-containing group and a carbon-containing group. The bond to the metal oxide/hydroxide particle surface is formed by reaction of the phosphorous-containing group with the metal oxide/hydroxide particle surface, so that the carbon-containing group of the material is oriented away from the metal oxide/hydroxide surface.
