【摘要】：采用商洛钒尾矿、钾长石和粘土为原料制备泡沫陶瓷,在确定原料配方的基础上,研究烧结温度、升温速率和保温时间对泡沫陶瓷体积密度和抗压强度的影响,确定最优烧成工艺参数,制得质量轻、强度高、导热系数低的高性能泡沫陶瓷材料。结果表明:8℃/min从室温至1000℃,再以3℃/min的升温速度烧至1135℃保温30 min,在此烧成工艺条件下制备的泡沫陶瓷试样的体积密度为420 kg/m3,抗压强度为3.1 MPa,导热系数为0.09 W/(m·K)。
[Abstract]:Foam ceramics were prepared by using Shangluo vanadium tailings, potassium feldspar and clay as raw materials. The effects of sintering temperature, heating rate and holding time on bulk density and compressive strength of foam ceramics were studied on the basis of determining the formula of raw materials. The high performance foam ceramic material with light mass, high strength and low thermal conductivity was obtained by determining the optimum sintering process parameters. The results show that the foam ceramic samples prepared at the temperature range of 8 鈩，
