| 21. | The metal aluminate CaAl 2 O 4 is used in the cement industry as a hydraulic material.
|
| 22. | In the bulky borates and aluminates, the negative charge is symmetrically distributed over many electronegative atoms.
|
| 23. | Brasseler's EndoSequence bioceramic sealers are tricalcium silicate-based materials without any calcium aluminate phase.
|
| 24. | The initial reaction ( 1 ) consumes sodium hydroxide and produces both hydrogen gas and an aluminate byproduct.
|
| 25. | Georges Friedel also synthesised calcium aluminate in 1903 in the framework of his work on the macles theory.
|
| 26. | Before storage, the catalyst can be washed with distilled water at ambient temperature to remove remaining sodium aluminate.
|
| 27. | Sodium beta alumina is a non-stoichiometric sodium aluminate known for its rapid transport of Na + ions.
|
| 28. | It is an important phase in calcium aluminate cements and is an intermediate in the manufacture of Portland cement.
|
| 29. | Off-white clinker has a calculated C 3 A ( tricalcium aluminate ) of 7-9 %.
|
| 30. | It bonds covalently in most of its compounds; has an amphoteric oxide; and can form anionic aluminates.
