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.

Abstract: A method of forming a 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.

Abstract: An abrasive grain is disclosed and may include a body. The body may define a length (1), 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: An fixed abrasive article is provided which includes a matrix material and abrasive particles embedded within the matrix material. The abrasive particles have a core--shell structure that includes a polycrystalline alpha alumina core and a shell layer overlying the polycrystalline alpha alumina core. The shell layer includes a material selected from the group consisting of silicon oxide and zir-conium oxide. Also the polycrystalline alpha alumina core includes grains and having an average grain size of not greater than about 500 nm.
