摘要： The subject of the invention is a method for the preparation of carrier colloidal powder with high specific surface area for application of a thin layer and/or nanoparticles. Due to a very large specific surface area and porosity of the carrier particles certain properties of nanoparticles that they exhibit due to their small size are preserved or even increased in comparison with the use of nanoparticles as such. Handling the so prepared composite colloidal particles with an increased specific surface area is very simple. The carrier powder is produced by exploiting hydrolysis of the AIN powder, wherein during a reaction between AIN and water the decomposed AIN particles are replaced by a number of agglomerates of porous particles from AIOOH with a high specific surface area that can be subsequently thermally treated in order to obtain the particles from one of the transitional forms of AI2O3, i. e. ?-, d- or ?-??2?3, without any significant change in the morphology of the particles.
摘要翻译：本发明的主题是用于制备具有高比表面积的载体胶体粉末以施加薄层和/或纳米颗粒的方法。由于载体颗粒的非常大的比表面积和孔隙率，与使用纳米颗粒本身相比，它们由于其小尺寸而表现出的纳米颗粒的某些性质被保留或者甚至增加。处理如此制备的具有增加的比表面积的复合胶体粒子非常简单。通过利用AlN粉末的水解生产载体粉末，其中在AlN和水之间的反应期间，分解的AlN颗粒被来自AlOOH的多个多孔颗粒的聚集体代替，所述多个聚集体具有高比表面积，所述高比表面积可随后在为了从Al 2 O 3的一种过渡形式获得颗粒，即 γ-，d-或γ-β2→3，而颗粒的形态没有任何显着变化。
