STRONG LOW DENSITY CERAMICS |
摘要 |
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 impurities in the starting materials. Compositions, methods of manufacture, and uses are given.
