    摘要： Stable vermiculite dispersions which are substantially free of settling and a method of preparing same are provided. The dispersions are obtained by treating the vermiculite platelets of which the dispersion is comprised with an anionic chelating agent. The anionic chelating agent enhances the rate and degree of swelling of the vermiculite in an aqueous medium. The swollen vermiculite is delaminated by shearing to provide the inventive dispersions.

    摘要： Novel aqueous inorganic particle slurries, wherein some of the particles have had their charge potential altered to a sufficient extent to prevent segregation or settling of the particles, are described, along with a method for their preparation. The method of forming slurries of negatively charged particles comprises treating some of the particles with a cationic agent to reduce their charge and mixing these treated particles with the remainder of the particles to form a thick, cream-like flowable composition of a thixotropic nature. When slurries of positively charged particles are to be formed, an anionic agent is used instead of a cationic agent.

    摘要： Nacreous pigments having improved light fastness are based on mica platelets coated with titanium dioxide and, optionally other additional metal oxides. These pigments carry an additional thin manganese oxide layer. The pigments are prepared in a process wherein mica is coated in aqueous suspension with one or more titanium dioxide hydrate layers and, optionally, with further metal oxide layers, mixed with the titanium dioxide hydrate or separately therefrom, and then is washed, dried and calcined. The process further comprises precipitating an additional layer of manganese hydroxide onto the base pigment, either directly after coating with the titanium dioxide hydrate and/or metal oxide layers or after the calcination thereof. The flakes are the washed, dried and calcined.The new pigment can be used for pigmenting plastics, lacquers, paints and cosmetics, inter alia.

    摘要： A coating composition is described comprising a thermoplastic or thermosetting resin material containing a pigment composition. The pigment composition contains about 5 to about 90% iron oxide encapsulated mica particles. When used in a multi-coat coating process as a basecoat overcoated with a transparent overcoat, an article is produced which not only produces improved pearlescent color effects, but is stable to the elements as well.

    摘要： The present invention is related to the production of crystal-containing gels and papers, films, fibers, boards, and coatings made therefrom. The process for making the gels comprises three general steps: first, a fully or predominantly crystalline body is formed containing crystals consisting essentially of a lithium and/or sodium water-swelling mica selected from the group of fluorhectorite, hydroxyl hectorite, boron fluorphlogopite, hydroxyl boron phlogopite, and solid solutions among those and between those and other structurally-compatible species selected from the group of talc, fluortalc, polylithionite, fluorpolylithionite, phlogopite, and fluorphlogopite; second, that body is contacted with a polar liquid, desirably water, to cause swelling and disintegration of the body accompanied with the formation of a gel; and, third, the solid:liquid ratio of the gel is adjusted to a desired value depending upon the application therefor. Where papers, films, fibers, boards, or coatings are desired, such are prepared from the gel, and, to impart good chemical durability thereto, are thereafter contacted with a source of large cations to effect an ion exchange reaction between the large cations and the Li.sup.+ and/or Na.sup.+ ions from the interlayer of the crystals, and the products then dried. Glass-ceramic bodies are the preferred starting materials.
