Patent number: 5891421Abstract: Precipitated silica compositions, and methods for making the same, with improved dentifrice performance characteristics. In particular, precipitated silica compositions of the present invention have a 40% slurry viscosity build of less than approximately 20,000 centipoise and a 10% Brass Einlehner abrasion value of approximately 2.5 to 20.0 mg loss/100,000 rev. Precipitated silica compositions of the present invention also have reactor slurry average particle sizes (50%) of approximately 10 to 50 .mu.m. Methods for preparing precipitated silicas of the present invention include the steps of: (a) adding sodium silicate and a mineral acid to a reactor, thereby initiating a precipitation reaction between the reactor contents; and (b) subjecting the reactor contents to shearing forces as the reaction proceeds.Type: GrantFiled: March 22, 1996Date of Patent: April 6, 1999Assignee: J.M. Huber CorporationInventors: Patrick D. McGill, Satish K. Wason

Patent number: 5223235Abstract: A family of novel and unique synthetic alkali metal alumino-silicates (SAMS) are produced by the hydrothermal reaction between kaolin and alkali metal silicates. The integrated composition of the SAMS products is a unique entity having an overall composition ofxM.sub.2 O:Al.sub.2 O.sub.3 :ySiO.sub.2 :zH.sub.2 Owhere x is the number of moles of alkali metal oxide and is an integer from 0.01 to 2.0, M is the alkali metal, y is the number of moles of SiO.sub.2 in the unique SAMS compositions and is an integer greater than 2.0, and z is the number of moles of bound water and is an integer ranging from 1.0 to 5.0. The unique SAMS compositions are structured materials in which the structure can be controlled, and are therefore useful as functional fillers, as TiO.sub.2 extenders, as silica extenders or as reinforcing agents for paper, paint, rubber, plastics and specialty products.Type: GrantFiled: January 11, 1991Date of Patent: June 29, 1993Assignee: J.
