The purpose of the study was to investigate the possibility of using press filter cake (PFC) waste from sugar production in the preparation of anorthite ceramics. In this study, at first step, the properties of anorthite ceramic compositions produced using different proportions of press filter cake (PFC) as calcium oxide source and chamotte as aluminosilicate source were investigated. A single anorthite phase was obtained in samples containing high PFC ratios sintered at high temperature. In the second step, the PCH-35 (35% PFC plus 65% chamotte) ceramic composition was statistically analyzed to examine grinding parameters and sintering temperatures. This composition was ground and sintered at different parameters to investigate the effects on physical, mechanical, and morphological properties on anorthite ceramics. The results indicated that the anorthite phase formed in the powders sintered at 1200 °C and 1300 °C after grinding was the major phase. With increasing sintering temperature, grinding speed, and time, the samples exhibited lower porosity, higher bulk density, and compressive strength. With the sintering of the samples at 1200 °C, the percentage of apparent porosity decreased from 49.95 to 25%, while the bulk density value increased from 1.36 to 2.03 g/cm3 with increasing grinding speed and time. When the samples were sintered at 1300 °C, the percentage of apparent porosity decreased from 49.59 to 0.33%, while the bulk density value increased from 1.33 to 2.54 g/cm3 with increasing grinding speed and time. The compressive strength results (from 26 to 82 MPa) increased due to body densification with the effect of increasing sintering temperature, grinding speed, and time.

从制糖固体废物中制备钙长石陶瓷及其表征:研磨参数的统计分析

该研究的目的是研究使用制糖过程中产生的压滤饼 (PFC) 废料制备钙长石陶瓷的可能性。在这项研究中,首先,研究了使用不同比例的压滤饼(PFC)作为氧化钙源和熟泥作为铝硅酸盐源生产的钙长石陶瓷组合物的性能。在高温下烧结的含有高 PFC 比率的样品中获得了单一的钙长石相。在第二步中,对 PCH-35(35% PFC 加 65% 熟料)陶瓷成分进行统计分析,以检查研磨参数和烧结温度。该组合物在不同参数下进行研磨和烧结,以研究对钙长石陶瓷的物理、机械和形态特性的影响。结果表明,磨削后在1200℃和1300℃烧结的粉末中形成的钙长石相是主要相。随着烧结温度、研磨速度和时间的增加,样品表现出较低的孔隙率、较高的堆积密度和抗压强度。随着样品在 1200 ℃的烧结,表观孔隙率百分比从 49.95 下降到 25%,而体积密度值从 1.36 增加到 2.03 g/cm3随着研磨速度和时间的增加。当样品在 1300 ℃烧结时,随着研磨速度和时间的增加,表观孔隙率百分比从 49.59 下降到 0.33%,而堆积密度值从 1.33 增加到 2.54 g/cm 3 。随着烧结温度、研磨速度和时间的增加,由于体致密化,抗压强度结果(从 26 到 82 MPa)增加。
