  • Smoking article wrapper having filler of hydromagnesite/magnesium hydroxide and smoking article made with said wrapper
    Patent number: 5979461
    Abstract: Hydromagnesite-magnesium hydroxide compositions which, when used as fillers in smoking article wrappers, significantly reduce the amount of sidestream smoke produced by the burning smoking article while providing the smoking article with good subjective characteristics.
    Type: Grant
    Filed: March 24, 1997
    Date of Patent: November 9, 1999
    Assignee: Philip Morris Inc.

  • Method for making a carbonaceous heat source containing metal oxide
    Patent number: 5595577
    Abstract: A carbonaceous heat source comprising metal oxides and methods for making such heat source are provided. The heat source has an ignition temperature substantially lower than conventional carbonaceous heat sources, while at the same time produces virtually no carbon monoxide upon combustion. The heat source is prepared by pre-forming the carbon and binder materials into a desired shape, and then treating the shape with a sol containing metal oxide precursors. The metal oxide precursors are deposited in the pre-formed carbon shape. Further treatment converts the deposited metal oxide precursors into metal oxide.
