CaCO_3微粉对锆酸钙性能的影响
|
摘要
以Ca(OH)_2和m-ZrO_2为原料,按物质的量1:1进行配料,添加不同质量分数的CaCO_3微粉,混料均匀后压样,经1600℃保温3 h后制备得到锆酸钙(CaZrO_3)。利用显气孔体密测定仪、X射线衍射仪、扫描电子显微镜和X’Pert plus图象处理软件分析CaCO_3微粉对锆酸钙材料烧结性能、物相组成及微观结构的影响。结果表明:当没有添加CaCO_3微粉时,试样烧结前后线收缩率为8.23%,体积密度为3.40 g.cm儃3,显气孔率为14.5%,CaZrO_3晶粒尺寸为4.08μm;当加入质量分数为8%CaCO_3微粉时,试样烧结前后线收缩率为14.89%,制备锆酸钙体积密度为4.02 g.cm~(-3),显气孔率为8.6%,CaZrO_3晶粒尺寸为5.45μm;由此可见,添加少量CaCO_3微粉有利于锆酸钙烧结致密性和晶粒长大。
Using analytical Ca(OH)_2 and m-ZrO_2 as the raw materials in the mole ratio of 1:1, the mixtures were added by CaCO_3 powders in the different contents by mass, the calcium zirconate(CaZrO_3) was synthesized by sintering the compacted samples at 1600 ℃ for 3 h. The effects of CaCO_3 powders on sintering properties, phase composition, and microstructures of CaZrO_3 were studied by apparent porosity density determinator, X-ray diffraction(XRD), scanning electron microscope(SEM), and X'Pert plus software. The results show that, without the addition of CaCO_3, the sharking of CaZrO_3 samples is 8.23%, the bulk density and apparent porosity of CaZrO_3 sintered at 1600 ℃ are 3.40 g.cm~(-3) and 14.5%, respectively, and the grain size of CaZrO_3 is only 4.08 μm.With the addition of CaCO_3 in mass fraction of 8%, the sharking of CaZrO_3 samples is 14.89%, the bulk density and apparent porosity of CaZrO_3 sintered at 1600 ℃ are 4.02 g.cm~(-3) and 8.6%, respectively, and the grain size of CaZrO_3 reaches to 5.45 μm. Thus, it can be seen that the CaCO_3 addition in appropriate content can promote the sintering compactness and grain growth of CaZrO_3.
