摘要： Provided is a pyrogenically prepared SiO2 powder in the form of aggregated primary particles having a statistical thickness surface area (STSA) of 10-500 m2/g, a thickening action based on the STSA of 4-8 mPas·g/m2, and a micropore volume of 0.03-0.07 cm3/g, and a process for preparing the pyrogenic SiO2 powder, which involves: introducing hydrolyzable silicon compounds, a primary gas comprising oxygen, and a primary combustion gas into a mixing chamber to produce a mixture; igniting the mixture in a burner to produce a flame, which is burned into a reaction chamber to produce the pyrogenic SiO2 powder and gaseous substances; and separating the pyrogenic SiO2 powder from the gaseous substances, wherein a ratio of the amount of primary combustion gas introduced to a stoichiometric amount of primary combustion gas required is referred to as gammaprimary and has a value of less than 1, and wherein a ratio of the amount of primary gas comprising oxygen introduced to a stoichiometric amount of primary gas comprising oxygen required is referred to as lambdaprimary and has a value of greater than 1.
摘要翻译：本发明提供一种热解法制备的具有10-500m 2 / g的统计厚度表面积（STSA）的聚集的一次颗粒形式的二氧化硅粉末，基于STSA的增稠作用为4-8mPas.g / m2，以及微孔体积为0.03-0.07cm 3 / g，以及制备热解SiO 2粉末的方法，其包括：将可水解的硅化合物，包含氧的一次气体和一次燃烧气体引入混合室中以产生混合物; 在燃烧器中点燃混合物以产生火焰，其被燃烧到反应室中以产生热解SiO 2粉末和气体物质; 并将所述热解SiO 2粉末与所述气态物质分离，其中将所述一次燃烧气体的一次燃烧气体的量与所述一次燃烧气体的化学计量量的比率称为原料气体，其值小于1，其中，引入到化学计量量的包含所需氧气的主要气体中的包含氧气的初级气体的量被称为羔羊肉，并且具有大于1的值。
