Patent

CA 2721916

A synthetic ceramic proppant composition contains an aluminate-borate phase or an aluminate-borate-silicate phase or both and at least one additional phase that adds strength and decreases apparent specific gravity and is formed because of the inclusion of certain inorganic salts and/or metallic oxides in the precursor mixture either as separate components or as impuri-ties in the starting materials. Compositions, methods of manufacture, and uses are given.

L'invention porte sur une composition d'agent de soutènement céramique synthétique contenant une phase d'aluminate-borate ou une phase d'aluminate-borate-silicate ou les deux et au moins une phase supplémentaire qui augmente la résistance et diminue la densité apparente et qui est formée du fait de l'inclusion de certains sels inorganiques et/ou oxydes métalliques dans le mélange précurseur soit en tant que composants séparés soit en tant qu'impuretés dans les matières de départ. L'invention porte également sur des compositions, des procédés de fabrication et des utilisations.
