Synthesis of Cordierite Powders by Low Temperature Combustion Method
The cordierite powders have been synthesized by low temperature combustion technique using urea as fuel,nitrates as oxidizer and silicic acid as silica source.The sintering behavior and crystallization process were investigated.The results showed that the powders could be sintered at a temperature lower than 1000 ℃.The μ-cordierite crystallized from glass at first,and then transformed into α-cordierite at higher temperature.The obtained cordierite based glass ceramics at different temperatures have low dielectric constant (4.16 ~ 5.02 at 1 MHz) and low dielectric dissipation factor (≈ 0.003 at 1 MHz) as well as low temperature sintering behavior,which is compatible for electronic packaging.
