Process for Preparing Mullite Powder and Fabrication of Structural Bodies Therefrom.
Abstract
In the patent application a process is provided for preparing high purity, submicron, mullite powder (3Al2O3.2SiO2) by hydrolytically decomposing aluminum tris isopropoxide and silicon tetrakis isopropoxide in the presence of ammonium hydroxide or a very dilute mineral acid. The powder as prepared as well as that subjected to calcination has an orthorhombic crystal structure. Structural bodies of near theoretical density can be fabricated by vacuum hot pressing the powder. Beacuse of its large surface area, the mullite powder is an excellent catalyst and catalyst carrier, especially for hydrocarbon cracking catalysts.
