Preparation of titania-silica glasses by the gel method

Abstract A series of bulk glasses in the $ TiO_{2} $-$ SiO_{2} $ system have been prepared by hydrolysing the mixture solution of Ti($ OC_{3} $$ H_{7} $)4 and Si($ OC_{2} $$ H_{5} $)4 with water and hydrochloric acid, and slowly heating the resultant gels up to 800° C. The conversion of gels to glas...

The conversion of gels to glasses was examined by the measurements of Vickers' hardness, IR and TGA. The properties of $ TiO_{2} $-$ SiO_{2} $ glasses in the less than 12.9 wt% $ TiO_{2} $ range obtained by the gel method were very similar to those of oxide glasses made by the flame hydrolysis process. These glasses showed ultra-low thermal expansion, but the precipitation of anatase remarkably increased the thermal expansion. In the less than 10.4 wt% $ TiO_{2} $ range, the glasses obtained by heating up to 800° C were not crystallized at 1000° C or higher, while in the more than 20 wt% $ TiO_{2} $ range anatase was precipitated at 900° C. It was found that glasses obtained by the gel method were a true solid solution at least up to 7.4 wt% $ TiO_{2} $ composition.

These glasses showed ultra-low thermal expansion, but the precipitation of anatase remarkably increased the thermal expansion. In the less than 10.4 wt% $ TiO_{2} $ range, the glasses obtained by heating up to 800° C were not crystallized at 1000° C or higher, while in the more than 20 wt% $ TiO_{2} $ range anatase was precipitated at 900° C. It was found that glasses obtained by the gel method were a true solid solution at least up to 7.4 wt% $ TiO_{2} $ composition.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Oxide</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Polymer</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Precipitation</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">TiO2</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Hydrolysis</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Yamada, Tadashi</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Saito, Hajime</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Journal of materials science</subfield><subfield code="d">Kluwer Academic Publishers, 1966</subfield><subfield code="g">18(1983), 10 vom: Okt., Seite 3137-3142</subfield><subfield code="w">(DE-627)129546372</subfield><subfield code="w">(DE-600)218324-9</subfield><subfield code="w">(DE-576)014996774</subfield><subfield code="x">0022-2461</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:18</subfield><subfield code="g">year:1983</subfield><subfield code="g">number:10</subfield><subfield code="g">month:10</subfield><subfield code="g">pages:3137-3142</subfield></datafield><datafield tag="856" ind1="4" ind2="1"><subfield code="u">https://doi.org/10.1007/BF00700798</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_11</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_20</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_23</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_30</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_31</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_32</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_40</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_62</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_65</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_70</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_2004</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_2006</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_2015</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_2020</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_2021</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_2057</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_2333</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_4082</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_4305</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_4306</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_4319</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_4323</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_4336</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_4700</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">18</subfield><subfield code="j">1983</subfield><subfield code="e">10</subfield><subfield code="c">10</subfield><subfield code="h">3137-3142</subfield></datafield></record></collection>

abstract	Abstract A series of bulk glasses in the $ TiO_{2} $-$ SiO_{2} $ system have been prepared by hydrolysing the mixture solution of Ti($ OC_{3} $$ H_{7} $)4 and Si($ OC_{2} $$ H_{5} $)4 with water and hydrochloric acid, and slowly heating the resultant gels up to 800° C. The conversion of gels to glasses was examined by the measurements of Vickers' hardness, IR and TGA. The properties of $ TiO_{2} $-$ SiO_{2} $ glasses in the less than 12.9 wt% $ TiO_{2} $ range obtained by the gel method were very similar to those of oxide glasses made by the flame hydrolysis process. These glasses showed ultra-low thermal expansion, but the precipitation of anatase remarkably increased the thermal expansion. In the less than 10.4 wt% $ TiO_{2} $ range, the glasses obtained by heating up to 800° C were not crystallized at 1000° C or higher, while in the more than 20 wt% $ TiO_{2} $ range anatase was precipitated at 900° C. It was found that glasses obtained by the gel method were a true solid solution at least up to 7.4 wt% $ TiO_{2} $ composition. © Chapman and Hall Ltd 1983
