英文摘要 Anorthite-based ceramic (ABC) materials have been proved to have better characteristics than traditional aluminum-based materials in the IC manufacturing. Many researches discussed the substitution substance to improve the properties in the firing processes, among then different sources such as Ca and Si were studied. Municipal solid waste incineration (MSWI) fly ash contains abundant of CaO and SiO2, it is possible to be used as the additive during the producing of ABC material after proper pretreatment, which will elevate the value greatly in the waste recovery process.
The study investigated the structure and dielectric properties of ceramic products through the mechanochemical synthesize and then sintering. MSWI fly ash was added to lower the sintering temperature and to improve the crystallization. The structure was identified by X-ray diffraction (XRD).
The results showed that, the sintering temperature range of fly ash addition synthesis of ABC materials is 1500℃ to 971℃. At the condition of 1200℃ and 1 h sintering exhibited the best dielectric characteristics εr 4.16, dielectric loss factor 0.006 and thermal expansion coefficient (CET) 3.90×10-6 /℃, which is better than traditional alumina substrate. In addition, heavy metals concentration of TCLP are all far below the limitations of hazardous waste identification.
