    The Influence of Li〈sup〉+〈/sup〉 on the Sintering of Cordierite Glass Ceramic (2007)
    s.l. ; Stafa-Zurich, Switzerland
    Key engineering materials Vol. 336-338 (Apr. 2007), p. 1859-1861 
    Details
    ISSN: 1013-9826
    Source: Scientific.Net: Materials Science & Technology / Trans Tech Publications Archiv 1984-2008
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: The effects of Li+ addition on the sintering and microstructural evolution of cordierite wereanalyzed. As nucleating agent, the Li+ additive decreased the expansion coefficient and dielectricconstant. The doping of Li+ was found to block the phase transition from μ-cordierite to α-cordierite andincrease sintering temperatures. The effect of Li+ on the activation of cordierite can be attributed to thenucleation of cordierite. Too much Li+ will inhibit the cordierite crystallization and encourageamblygonite crystallization. Cordierite powders were prepared by sol-gel processing

    The Influence of Bi〈sup〉3+〈/sup〉 on the Sintering of Cordierite Glass Ceramic (2007)
    s.l. ; Stafa-Zurich, Switzerland

    Notes: The effects of Bi3+ addition on the sintering performance and microstructural evolution of cordierite were analyzed in this paper. Cordierite powders were prepared by sol-gel processing. As nucleating agent, the Bi3+ additive was found to promote the phase transition from µ-cordierite to α-cordierite and decrease sintering temperatures. The effect of Bi3+ on the activation of cordierite can be attributed to the nucleation of cordierite. The doping of Bi3+ increased the expansion coefficient and dielectric constant. Too much Bi3+ will inhibit the cordierite crystallization and encourage anorthite crystallization

    Synthesis of Cordierite Powders by Low Temperature Combustion Method (2008)
    s.l. ; Stafa-Zurich, Switzerland
    Key engineering materials Vol. 368-372 (Feb. 2008), p. 192-194 
    Details
    ISSN: 1013-9826
    Source: Scientific.Net: Materials Science & Technology / Trans Tech Publications Archiv 1984-2008
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: The cordierite powders have been synthesized by low temperature combustion technique usingurea as fuel, nitrates as oxidizer and silicic acid as silica source. The sintering behavior and crystallizationprocess were investigated. The results showed that the powders could be sintered at a temperature lowerthan 1000 ºC. The μ-cordierite crystallized from glass at first, and then transformed into α-cordierite athigher temperature. The obtained cordierite based glass ceramics at different temperatures have lowdielectric constant (4.16 ~ 5.02 at 1 MHz) and low dielectric dissipation factor (≈ 0.003 at 1 MHz) as wellas low temperature sintering behavior, which is compatible for electronic packaging
