The present study aimed at using plant waste (Musa Paradisiaca) for manufacturing clay‐based ceramics in order to promote lower sintering temperature while preserving the properties of use. Two kaolinic‐illitic clays (NZ1 and KO) from Central African Republic were used mixed with 1 to 10 mass% of the plant waste (MP). The clays and the waste exhibited accessory phases: quartz and iron oxides, and K2O respectively. MP was collected, dried and sieved (<100 μm) previously to its mixture with clays. According to the sintering behavior of KO and NZ1 derived from thermodilatometry, the densification was obtained after firing at 1200°C. Results showed that open porosity decreased from 35% to 17% with increasing temperature in the range 900 to 1200°C for KO and NZ1. This porosity remained in the range 30%‐40% while increasing the MP content (firing at 1000°C for 1h.). The optimized MP content was 3 and 5 mass% for KO and NZ1 clay materials respectively. The compressive strength and thermal conductivities were improved compared to clay samples without MP fired at 1200°C. Moreover a significant decrease in the sintering temperature was achieved, leading to energy saving in line with sustainability issues.

植物废料对页硅酸盐基陶瓷使用性能和微观结构的影响
本研究旨在利用植物废料(Mus Paradisiaca)生产粘土基陶瓷,以促进较低的烧结温度,同时保持使用性能。使用了来自中非共和国的两种高岭土-硅质粘土(NZ1和KO)与1至10质量%的植物废料(MP)混合。粘土和废物表现出辅助相:石英和氧化铁以及K 2分别为O。收集MP,干燥并过筛(<100μm),然后将其与粘土混合。根据源自热膨胀计的KO和NZ1的烧结行为,在1200℃下烧成后获得致密化。结果表明,随着温度的升高,KO和NZ1的开孔孔隙率从35%降低到17%。该孔隙率保持在30%-40%的范围内,同时增加了MP的含量(在1000°C煅烧1h)。KO和NZ1粘土材料的最佳MP含量分别为3和5质量%。与未在1200°C燃烧MP的粘土样品相比,其抗压强度和热导率得到了改善。此外,实现了烧结温度的显着降低,从而根据可持续性问题实现了节能。
