Low temperature preparation ofβ-alumina by an alkoxide route
Abstract β-alumina has been prepared by the thermal decomposition of a mixture of sodium and aluminium isopropoxides followed by heating up to 1000°C. It has been found necessary to use sodium isopropoxide in excess (25–30%) for the complete formation ofβ-alumina at 1000°C. On the other hand one obt...

Low temperature preparation ofβ-alumina by an alkoxide route |
| abstract |
Abstract β-alumina has been prepared by the thermal decomposition of a mixture of sodium and aluminium isopropoxides followed by heating up to 1000°C. It has been found necessary to use sodium isopropoxide in excess (25–30%) for the complete formation ofβ-alumina at 1000°C. On the other hand one obtains a mixture ofβ-alumina andα-alumina when the starting materials are taken in the stoichiometric ratio $ Na_{2} $O:$ 11Al_{2} $$ O_{3} $. DTA, TG and DTG studies of a mixture of sodium and aluminium isopropoxide showedβ-alumina formation at 1000°C. © the Indian Academy of Sciences 1988 |

It has been found necessary to use sodium isopropoxide in excess (25–30%) for the complete formation ofβ-alumina at 1000°C. On the other hand one obtains a mixture ofβ-alumina andα-alumina when the starting materials are taken in the stoichiometric ratio $ Na_{2} $O:$ 11Al_{2} $$ O_{3} $. DTA, TG and DTG studies of a mixture of sodium and aluminium isopropoxide showedβ-alumina formation at 1000°C.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">-alumina</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">sodium isopropoxide</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">aluminium isopropoxide</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">low temperature preparation</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Sinha, A P B</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Bulletin of materials science</subfield><subfield code="d">Springer India, 1979</subfield><subfield code="g">11(1988), 4 vom: Dez., Seite 281-286</subfield><subfield code="w">(DE-627)130547476</subfield><subfield code="w">(DE-600)781668-6</subfield><subfield code="w">(DE-576)9130547474</subfield><subfield code="x">0250-4707</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:11</subfield><subfield code="g">year:1988</subfield><subfield code="g">number:4</subfield><subfield code="g">month:12</subfield><subfield code="g">pages:281-286</subfield></datafield><datafield tag="856" ind1="4" ind2="1"><subfield code="u">https://doi.org/10.1007/BF02744562</subfield><subfield code="z">lizenzpflichtig</subfield><subfield code="3">Volltext</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_A</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SYSFLAG_A</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_OLC</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OLC-TEC</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_70</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">11</subfield><subfield code="j">1988</subfield><subfield code="e">4</subfield><subfield code="c">12</subfield><subfield code="h">281-286</subfield></datafield></record></collection>
