In this work the effect of CoO additive on the formation of mullite from Al2O3-SiO2 diphasic gel has been studied. The diphasicgel precursor for mullite was synthesized by sol-gel route following aqueous phase colloidal interaction of aluminiumhydroxide and silicic acid. The precursor gel powder...
SiO2溶胶 1. The results show that SiO2 sol forms sub-μm film on corundum-mullite particles, improve homogeneous distribution of SiO2 in the materials and controls the microstructure of the materials. 加入SiO2溶胶产生的莫来石反应化和微裂纹增韧是刚玉-莫来石质材料热震稳定性提高的主要原因。 2. ...
合成了一种查尔酮类有机染料4-N,N-二甲胺基查尔酮(DMAC),探讨了其在不同溶剂中的荧光性质;分别研究了它在二氧化硅(SiO2)溶胶-凝胶(Sol-gel)玻璃、聚甲基丙稀酸甲酯(PMMA)与斯托克斯(stokes)、PMMA/SiO2sol-gel复合玻璃中的光物理性质;探讨了它在各种介质中...
guxue 理论上说应该是多晶体薄膜,但不知你的分解温度够不够啊,拿去做个XRD分析不就清楚了吗, 小乔低调 XRD检测一下就知道了! baoyanl 可以查阅相关热处理文献,不是制备薄膜的,就是溶胶法制备SIO2的。就可以 lee.doctor 经煅烧过的用溶胶凝胶法制备的薄膜一般为多晶材料,你的处理条件下得到的最可能是多晶猜...
