摘要： Novel powders or particles are formed by associating them with relatively small proportions of hydrolysable liquid material. The resulting particle/liquid mass is placed in a mold and sintered under conditions of heat and pressure that enables at least some of the hydrolysable liquid to react within the sintered mass. The sintered mass displays a controllable range of properties such as increased density, increased tensile strength, and improved natural polish finish. The hydrolysable liquid may partially hydrolyze and/or react with the powders and particles, but the liquid is not completely (not 100%) reduced to an inorganic oxide prior to introduction to the mold and performance of the sintering process.

摘要： A process is described for applying a solid coating onto a surface of an article. The surface of an article has a first physical property measurable as a degree of hydrophobicity and/or hydrophilicity. A liquid coating of an oxidizable material containing at least one element other than carbon, hydrogen, oxygen and nitrogen is applied onto the surface of the article. The oxidizable material is oxidized on the surface to attach an oxidized material having said at least one element other than carbon, oxygen, nitrogen and hydrogen onto said surface. This process thereby changes the first physical property with respect to its hydrophobicity and/or hydrophilicity. The process is relatively gentle to the underlying surface, at least in part because of the moderate temperatures which may be used for oxidation, and a wide range of properties may be provided onto the surface by appropriate selection and/or mixing of the liquid material and selection of the surface. The process is particularly useful with particulate materials.

摘要： A dispersion for carrying at least one water-soluble material or water-dispersible material (especially ascorbic acid, Vitamin C) in a relatively stable form is described, the dispersion comprising an oil phase containing particles comprising water-soluble polymer, water-soluble material or water-dispersible material (ascorbic acid), and water. The dispersion preferably comprises particles which have number average diameter dimensions of less than 2 microns, more preferably less than 1 micron. The dispersion may comprise oil components such as, for example only, a mineral oil, silicone oil, or cosmetic oil. A method of forming a dispersion of solid particles which comprise water-soluble material or water-dispersible material (e.g., ascorbic acid) in a water-soluble polymer may comprise the steps of:a) forming a first solution of the water-soluble material or water-dispersible material (ascorbic acid), water and a water-soluble polymer,b) mixing the first solution with a second solution of a water in a surface active agent having an HLB of less than 12 or less than 10 and oil,c) dispersing the first solution and the second solution to form a mixture of the first solution and second solution, andd) cooling the mixture, solidifying the first solution to form particles dispersed in said oil. This method may have the emulsifying done at a temperature above 40.degree. C., preferably above 50.degree. C., more preferably above 55.degree. C.
