Abstract:
PROBLEM TO BE SOLVED: To provide sol-gel alumina abrasive grains which reduce the surface areas of the grains and allow the production of vitreous bonded products using low temperature vitreous bond materials without the production of black points, spots as a result of the incomplete combustion of organic components used in the production process. SOLUTION: The sol-gel alumina abrasive grains are characterized by coating the alumina abrasive grains with a ceramic oxide and containing alpha alumina crystals having particle diameters of ≤2 μm.

Abstract:
PROBLEM TO BE SOLVED: To provide a method of forming a carrier material composed of alumina hydrate as a base material. SOLUTION: A method of forming the carrier material suited to use in Fischer-Tropsch reactions includes forming a dispersion of first and second hydrated alumina materials in a liquid dispersant, such as an acid solution. The first alumina can be derived from an alkali aluminate, such as is formed in the Bayer reaction. The second hydrated alumina can be derived from high purity aluminum, such as via conversion to an alkoxide. The dispersion is spray dried to form particles which are heat treated to form a carrier material having low levels of impurities. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
An abrasive grain is disclosed and may include a body. The body may define a length (l), a height (h), and a width (w). In a particular aspect, the length is greater than or equal to the height and the height is greater than or equal to the width. Further, in a particular aspect, the body may include a primary aspect ratio defined by the ratio of length:height of at least about 2:1. The body may also include an upright orientation probability of at least about 50%.

Abstract:
A boehmite particulate material is disclosed. The material is formed by a process that includes providing a boehmite precursor and boehmite seeds in a suspension, and heat treating the suspension to convert the boehmite precursor into boehmite particulate material. The boehmite particulate material has an aspect ratio of not less than 3:1.
