    摘要： A new method for producing precipitated silicas having a unique combination of physical and chemical properties is disclosed. The silicas are produced by acidulating a solution of an alkali metal silicate having a specific SiO.sub.2 /Na.sub.2 O mol ratio with an acid until precipitation just beings. At this point, the reaction mass is aged for a period of time and thereafter the acid addition is continued until the precipitated product is obtained. Products produced in accordance with the invention exhibit lower wet cake moisture and are characterized by their low structure, low oil absorption, high abrasiveness and high pack density, and as such are distinctly different from silicas used as reinforcing fillers in rubber. In a particularly advantageous embodiment, an adduct material, such as aluminum, is added to control the refractive index of the precipitated pigment. Products produced in this manner have particular utility for use as abrasion and gelling agents in clear toothpaste compositions.

    摘要： A method for producing precipitated silicic acid pigments and silicates having a unique combination of physical and chemical properties is disclosed. The pigments are produced by acidulating a solution of an alkali metal silicate with an acid until precipitation just begins. At this point the reaction mass is aged for a period of time and thereafter the acid addition is continued until the precipitated product is obtained. Pigments produced in accordance with the invention exhibit lower wet cake moisture (or higher percent solids) and are characterized by their low structure, low oil absorption, high abrasiveness and high pack density. The products can be used as abrasive and polishing agents in dentifrice compositions, in the production of molecular sieves, in paints and the like. In a particularly advantageous embodiment, an adduct material, such as aluminum, is added to control the refractive index of the precipitated pigment. Products produced in this manner have particular utility for use as abrasion and gelling agents in clear toothpaste compositions.

    摘要： Opacifying pigment particles consisting essentially of discrete, substantially spherical microcapsules each having a solid, polymeric shell and a solid, polymeric core are provided wherein discrete, inorganic pigment particles are dispersed in the polymeric core of the microcapsules. The inorganic pigment-loaded microcapsules are capable of providing a high degree of opacity and a predetermined degree of glossiness to a given substrate by varying the size of the microcapsules. In addition, the inorganic pigment-loaded microcapsules are retained by fibrous substrates to a much greater extent than are inorganic pigments per se.

    摘要： Highly dispersed oxides of metals and/or silicon are hydrophobized by treatment with volatilizable organosilicon compounds in the gas phase. The oxide particles either come fresh from the production plant or are previously absolutely dried, and activated i.e., freed of physically and chemically bound water, in a fluidized bed with a dry inert gas stream at a temperature of 550* to 1000*C., preferably 600* to 950*C. under normal pressure in a few seconds to a few minutes, preferably in a time of 1 to 60 seconds. The oxide particles are reacted with a stoichiometrical mixture of at least one dialkyldichlorosilane and water in the ratio of 1:1 at a temperature of 350*C. to 650*C. in an atmosphere of CO2. There can also be used diaryldichlorosilanes.
