Abstract

ABSTRAK Penelitian sintesis kalsium ferrit pencampuran dari sintesis CaCO₃ yang berbahan dasar batu kapur tuban dan sintesis Fe₂O₃ yang berbahan dasar dari pasir besi lumajang. Dalam penelitian ini menggunakan variasi perbandingan massa dan temperatur tahan kalsinasi untuk mengetahui karakterisasi pembentukan kalsium ferrit. Pembentukan sintesis kalsium ferrit dari pencampuran sintesis CaCO₃ yang di proses dari batu kapur menggunakan metode karbonasi dan sintesis Fe₂O₃. Selanjutnya, di proses menggunakan metode kopresipitasi dengan variasi komposisi massa 1:6 dan 1:12 dengan penahanan waktu kalsinasi 3 jam pada temperatur suhu 800˚C, 900˚C dan 1000˚C.

根据luma钢砂和Tuban石灰石制成的钙铁氧相描述

抽象研究合成的合成钙混合ferrit CaCO₃tuban石灰岩为基本材料的基本材料的合成和Fe₂O₃lumajang铁沙子。这项研究使用质量比较和耐烧焦温度的变化来了解钙ferrit形成的特性。合成的合成钙ferrit混合形成CaCO₃石灰岩构成的过程使用的碳酸和Fe₂O₃合成方法。后来,在用kopresipitasi方法成分变化过程质量1:6和1:12只是3个小时的时间气温800˚拘留,900˚C和1000˚是C。为了了解合成钙ferrit描述使用x射线Difraktogram (XRD)温度成分变化1:6质量和1:12只是三个小时的拘留900ºC的温度。利用扫描电子显微镜测试确定ferit颗粒。关键词:钙铁ferrit,沙子,石灰岩,闪综合钙铁氧体的抽象研究上的一个综合体。从《CaCO一个综合体。从石灰石Tuban₃哪种是制造一个综合体。》和Fe₂O₃哪种是改编自Lumajang的铁沙。在这项研究中，质量ratio和电阻的变化温度被用来塑造calcium ferrite的形成。钙之编队铁氧体的一个综合体。从调音和《一个综合体。CaCO₃哪种方法》是石灰石processed从用carbonation》和Fe₂O₃。一个综合体。Furthermore,用的是processed coprecipitation方法with a团composition variation of 1:6 and 1:12 with a持有文物》(3 800小时of calcination at temperatures of˚˚1000,900˚是C和C。到个重大characterization》用x光Diffractogram钙铁氧体(XRD)的一个综合体。and Variation of the团composition of 1:6的温度》和calcination 1:12用3小时拘留at a 900ºC的温度。用扫描电子显微镜来确定calcium ferrite particles的种子。燧石Calcium, iron sand, limestone, SEM
