501039000 | Pore-forming | 7 |
20090298667 | Controlled Gas Pore Formers in Extruded Ware - The present invention provides compositions and methods for producing porous ceramic articles. The compositions and methods comprise a ceramic precursor batch comprising an organic peroxide pore forming agent where the pore forming agent is an organo-adduct of hydrogen peroxide and an organic compound or an organic peroxide of the general formula R—O—O—R′. The organic peroxide pore forming agent is stable during extrusion and other methods for forming a green body and does not decompose until the green body is dried. | 12-03-2009 |
20110152056 | METHOD FOR MAKING HOLLOW MICROSPHERES - There is provided a method for making hollow microspheres including heating a feed under conditions sufficient to convert at least a portion of the feed into hollow microspheres, where the heating is conducted under a vacuum. There is also provided hollow microspheres made using this method. | 06-23-2011 |
20110152057 | HOLLOW MICROSPHERES - There is provided hollow microspheres that are essentially free of blowing agent. There is also provided hollow microspheres comprising perlite and having a single cell structure. | 06-23-2011 |
20130045853 | METHOD OF PRODUCING POROUS GLASS - Provided is a method of producing a porous glass having a high strength by a safe, simple process that does not involve the use of any high-temperature heat treatment or acid treatment step. The method includes: mixing 4 wt % or more to 6.5 wt % or less of sodium oxide, 26 wt % or more to 36 wt % or less of boron oxide, and 60 wt % or more to 68 wt % or less of silicon oxide; heating the mixed materials to melt the materials and cooling the molten materials to obtain a glass body; and a step involving bringing the glass body into contact with water without reheating the glass body to obtain the porous glass. | 02-21-2013 |
20130116107 | Foam Glass Having A Low Coefficient of Thermal Expansion and Related Methods - Foam glass may include natural glass, wherein the foam glass includes greater than 5% alumina by weight of the foam glass and has a coefficient of thermal expansion ranging between 4×10 | 05-09-2013 |
20160152513 | GLASS MICROBUBBLES, RAW PRODUCT, AND METHODS OF MAKING THE SAME | 06-02-2016 |
20160159683 | VERY LOW CRYSTALLINE SILICA FOAMED GLASS AND METHODS OF USING THE SAME - A foamed glass body, comprising a foamed glass portion and a pore portion. The pore portion includes a plurality of gas-filled pores generally homogeneously distributed throughout the foamed glass portion. The foamed glass portion has a cristobalite content of less than one volume percent. | 06-09-2016 |
