  • Catalytically active foam formation powder
    Patent number: 11578007
    Abstract: The present invention relates to the field of foam formation and stabilization, particularly foamed construction materials, such as cement. Disclosed are additives suitable to obtain mineral foams when added to the corresponding starting materials. The invention provides a ready-to-use product in the form of a solid particulate composition comprising hydrophobized particles (1) and catalytically active particles (2) as defined in claim 1. The invention further provides for manufacturing methods of such ready-to-use product.
    Type: Grant

  • Ultrastable particle-stabilized foams and emulsions
    Patent number: 8975301
    Abstract: Described is a method to prepare wet foams exhibiting long-term stability wherein colloidal particles are used to stabilize the gas-liquid interface, said particles being initially inherently partially lyophobic particles or partially lyophobized particles having mean particle sizes from 1 nm to 20 ?m. In one aspect, the partially lyophobized particles are prepared in-situ by treating initially hydrophilic particles with amphiphilic molecules of specific solubility in the liquid phase of the suspension.
