摘要： A process of preparing a biogenic silica comprising the steps of incinerating a silica bearing organic source at a temperature up to 1200° C. and allowing the incinerated silica organic source to cool; adding the incinerated and cooled silica bearing organic source to an alkaline solution that has either been preheated to a temperature up to about 65° C. or to be heated with the added organic source to a temperature up to about 65° C., the alkaline solution being contained in a vessel and having a pH up to 14; applying heat so that the added organic source and the alkaline solution in the vessel are at a temperature between 100° C. and up to about 300° C. for 1 to 4 hours, thereby forming an aqueous biogenic silica and undissolved impurities derived from the added organic source; and extracting the aqueous biogenic silica from the vessel. The extracted silica can be solidified into a solid form.

摘要： The invention relates to a heat protection element comprising at least one carrier element and a protective layer. The protective layer is an aqueous silicate composition that can be obtained from an alkali metal oxide and SiO2 and contains at least one alkyl siloxane, the alkyl groups being linear or branched C1-C4 alkyl groups. The invention also relates to a preferred aqueous dispersion containing silicon dioxide, characterised in that it contains the silicon dioxide in the form of precipitated silicic acid, the dispersion being stabilised by adding polyol and alkali hydroxide, especially potassium hydroxide. Such a dispersion is preferably solidified by adding caustic potash solution.

摘要： A dispersion comprising fine porous inorganic oxide particles, e.g., silica gel particles, wherein the particles have a median particle size below three microns. The dispersed particles have a porosity after drying in which at least about 0.50 cc/g of pore volume is from pores having a pore size of 600 Å or less as determined by nitrogen porosimetry. Embodiments prepared from silica gel have porosity after drying in which at least about 0.7 cc/g of pore volume is from pores having a diameter of 600 Å or smaller. The particles of the dispersion also can be described as having viscosity derived pore volume of at least about 0.5 g/cc. The dispersion is prepared by forming a dispersion from inorganic oxides having sufficient rigid structure to maintain porosity after milling and drying. After the inorganic oxide is selected, it is milled to have a median particle size of 0.05 to about 3 microns. In embodiments in which stable dispersions of fine porous particles are desired without the addition of substantial amounts of dispersant, or if dispersions having a median particle size less than one micron are desired, the dispersion is created by, for example, centrifuging the milled slurry to obtain a settled phase and a supernatant phase in which the median particle size is in the range of 0.05 to about 1 micron. The supernatant phase is then separated from the settled phase to create the final product.
