COAL STRUCTURAL CHARACTERISTICS OF BAYAH FORMATION BASED ON X-RAY DIFFRACTION ANALYSIS
نویسندگان
چکیده
The coal of Bayah Formation in Lebak Regency, Indonesia have been subjected to attenuated X-ray diffraction (XRD), study their chemical and structural characteristics. X-Ray Diffraction (XRD) has widely used throughout the world high accuracy identifying molecular structure coal. Curve-fitting analysis was employed characterize structural. Based on ASTM, rank from this area is high-volatile bituminous B. research results show all coals similar crystallite value d002 range 3.87 3.96, reflecting a low content crystalline structure. height (Lc) diameter (La) were increase, while decrease relation more mature coals. Due parameters (d002, Lc La) dominantly by disordered amorphous structure, with small amount

Structural Analysis of Pan Fiber by X-ray Diffraction
Polyacrylonitryle (PAN) fibers are used on a large scale in textile industry but, some sorts of PAN fibers are valuable precursors for specific carbon fiber (CF) due to their best fitness to the purpose e.g. for high strength CF or for active CF. The application of PAN as precursors of CF is based on its specific structure and texture. Thus, the properties of PAN base CF strongly depend on PAN ...
متن کاملSurface Hardness Measurment and Microstructural Characterisation of Steel by X-Ray Diffraction Profile Analysis
An X-ray diffraction line will broaden considerably when steels change into martensitic structure on quenching. The results presented in this paper show that X-ray diffraction technique can be employed for a rapid and nondestructive measurement of hardness of hardened steel. Measurement on various quenched and tempered steels showed that the breadth of its diffraction peak increased with increa...
متن کاملX-ray diffraction peak profile analysis of maraged Fe-Ni-Mn steels
X-ray diffraction peak profile analysis was used to identify changes in the lattice distortions during isothermal aging of Fe-10Ni-7Mn (wt. %) maraging steel. Integral peak breadths were analyzed using classical Williamson-Hall equation taking the elastic anisotropy into account. It was found that substantial lattice distortions rise during precipitation hardening which depend strongly on the s...
متن کاملRelation between Coal and Fly Ash Mineralogy, Based on Quantitative X-Ray Diffraction Methods
The proportion of amorphous or glassy material in a series of fly ashes has been evaluated by X-ray powder diffraction (XRD) using several different sample preparation and processing methods in conjunction with the Rietveld-based Siroquant quantitative X-ray diffraction analysis software package. The results of the different methods used were found to give consistent results and were also in ag...
متن کاملNano-structural Characterization of Post-annealed ZnO Thin Films by X-ray Diffraction and Field Emission Scanning Electron Microscopy
ZnO thin films were deposited on Si(400) substrates by e-beam evaporation technique, and then post-annealed at different annealing temperatures (200-800°C). Dependence of the crystallographic structure, nano-strain, chemical composition and surface physical Morphology of these layers on annealing temperature were studied. The crystallographic structure of films was studied using X-Ray Diffracti...
