Pyrogenically produced aluminum-silicon mixed oxides

摘要

Pyrogenically produced aluminum-silicon mixed oxides with a BET surface of more than 300 m²/g and a composition of 0.01 to 99.99% by wt. AI₂O₃, remainder SiO₂ are produced in accordance with the method of flame pyrolysis or preferably flame hydrolysis by a joint combustion of the gaseous raw substances. They can be used to produce coating colors, especially for inkjet papers or inkjet foils or other inkjet materials.
