A composition comprising cement and nano-sized crystalline particles of boehmite alumina or nano-sized crystalline particles of boehmite alumina which have been modified by the inclusion of silicon oxide, calcium oxide, or magnesium oxide. The boehmite alumina has an average crystallite size from about 2 nm to about 80 nm and a content of non-crystalline alumina of less than about 25 mol percent based on total aluminum.

Cement compositions containing nano sized boehmite crystallites

A process of producing an organically modified metal oxide wherein an aqueous slurry of a metal oxide which can be peptized in the presence of an acid is admixed with an aqueous slurry of an oregano silage having the formula RSiX, the mixture of the aqueous slurry and the oregano silage being thermally aged to produce a colloidal metal oxide sol which can be dried to produce a powder which is readily discernible in polar compounds such as alcohols, water and the like.
