  • Method for the treatment of mineral extender fillers
    Patent number: 4671973
    Abstract: This invention provides a method for the treatment of mineral extender fillers. The mineral extender filler is treated essentially simultaneously with a halogenated organosilane and a compound containing an active hydrogen, preferably ammonia. The reaction is conducted at atmospheric pressure and at a temperature at which the halogenated organosilane is gaseous, but preferably no higher than 250.degree. C. This method is fast, efficient and economical.

  • Process for agglomerating expanded perlite fines
    Patent number: 4064071
    Abstract: Expanded lightly milled perlite fines are mixed with aqueous alkali metal silicates and the wet mixture is dried at temperatures of from 600.degree. F up to 1400.degree. F in a moving air stream to form agglomerates which are useful as filteraids. The agglomerates may be heat treated in an indirect fired rotary kiln to further reduce the water solubility, and may be separated into size factions either before or after the heat treatment.
