Abstract

This study investigates the characterization of two clays obtained from the Safi and Fez regions, focusing on their analysis for filtration membrane applications. Various analytical techniques were employed, including chemical composition analysis, elemental analysis, mineralogical characterization, carbonate content determination, color assessment, plasticity evaluation, thermal treatment analysis (DTA-TG), mineralogical transformation study, fusion tests, membrane tests, and scanning electron microscopy (SEM).

The results reveal significant differences between the two clays regarding their chemical composition. The red clay exhibits a mineralogical composition comprising quartz, calcite, dolomite, hematite, illite, and kaolinite, whereas the gray clay contains quartz, calcite, dolomite, illite, talc, and montmorillonite. Furthermore, upon thermal treatment, both clays exhibit changes in their physical properties.

Despite the decrease in porosity and water absorption, as well as the increase in compression strength for both clays, the permeability of the grey clay increases, unlike the red clay, which exhibits a constant permeability beyond 1000 °C.

These findings highlight the diversity and industrial significance of clays from the Safi and Fez regions for filtration membrane applications. The contrasting properties of red and gray clays provide insights into their potential utilization in different industries. Exploring these clays’ behavior can lead to better filtration membranes and new industrial applications.

探索粘土的多样性：温度对物理化学变化、机械特性和渗透性的影响及其与膜应用的相关性

本研究调查了从萨菲和非斯地区获得的两种粘土的特性，重点分析了它们在过滤膜应用方面的特性。研究采用了多种分析技术，包括化学成分分析、元素分析、矿物学表征、碳酸盐含量测定、颜色评估、可塑性评估、热处理分析（DTA-TG）、矿物学转化研究、熔融试验、膜试验和扫描电子显微镜（SEM）。红色粘土的矿物成分包括石英、方解石、白云石、赤铁矿、伊利石和高岭石，而灰色粘土则含有石英、方解石、白云石、伊利石、滑石和蒙脱石。此外，经过热处理后，两种粘土的物理性质都发生了变化。尽管两种粘土的孔隙率和吸水率都有所下降，压缩强度也有所提高，但灰色粘土的渗透性却增加了，这与红粘土不同，后者的渗透性在 1000 °C 以上保持不变。红粘土和灰粘土截然不同的特性为它们在不同行业的潜在应用提供了启示。对这些粘土行为的探索将带来更好的过滤膜和新的工业应用。

期刊介绍： The Journal of the Spanish Ceramic and Glass Society publishes scientific articles and communications describing original research and reviews relating to ceramic materials and glasses. The main interests are on novel generic science and technology establishing the relationships between synthesis, processing microstructure and properties of materials. Papers may deal with ceramics and glasses included in any of the conventional categories: structural, functional, traditional, composites and cultural heritage. The main objective of the Journal of the Spanish Ceramic and Glass Society is to sustain a high standard research quality by means of appropriate reviewing procedures.
