Abstract:
Research has been conducted into the nature of geothermal rocks in Pamekasan. This place is located in Tlanakan Pamekasan. This study aims to determine the composition of mineral compounds in the soil so that fire can burst out from the soil and the soil does not melt. Three steps can be done with simple refinement and filtering methods, namely X-Ray Fluorescence (XRF), X-ray diffraction (XRD), and Scanning Electron Microscope (SEM). The results of XRF analysis show the element of Api Alam 1 is Ca 66.2%, Api Alam 2 is Si 37.4%, and in hot springs, is Si 39.6%. The XRD results show that mineral

Abstract:
The aim of the presented research was to analyze ceramic material based on cordierite as a function of activation time and sintering temperature. Three-component oxide mixture was prepared (MgO + Al2O3 + SiO2 in the ratio 2:2:5). To decrease the sintering temperature, 10 mass % Bi2O3 was added to this mixture. The mixtures were mechanically activated for 5 and 240 minutes in a ceramic ball mill. Activated mixtures were sintered at temperatures of 1173-1573K. XRD method was used to determine the structural transformations of the obtained products.

Abstract This study investigates the mechanism of formation of calcareous deposits on cathodically protected BS EN 10027-1 S355 J2G4 steel in boiling synthetic seawater. Steel specimens were arc sprayed with commercially pure aluminum (99.5%) and a ≈4% holiday was drilled into the coating to expose the underlying steel. The specimens were then immersed in boiling (101±1°C) ASTM D1141 seawater solution for approx. 5000 hours. The potential was monitored and the linear polarization resistance (LPR) method was used to obtain the corrosion rate. After completion of the test, the pH of the solution

Abstract In this work, a variety of polymers were evaluated as precipitation inhibitors for magnesium ammonium phosphate (struvite) in aqueous solution. The polymers tested include 1) homopolymers of acrylic acid and methacrylic acid of varying molecular weight (MW), maleic acid, 2-ethyloxazoline, 2) acrylic acid based co- and terpolymers containing monomers with different functional groups and 3) natural, bio- and hybrid based polymers. The results reveal that polymer performance as a struvite inhibitor is strongly affected by polymer dosage, MW, and ionic charge of the functional group. It h

Abstract CO2 corrosion experiments of N80 steel with and without small amounts of O2 were performed using high temperature and high pressure autoclaves. Corrosion morphology and corrosion scale were investigated by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and X-ray diffraction (XRD), respectively. The results indicate that CO2-O2 corrosion rates were remarkably greater than that of CO2 corrosion. CO2-O2 corrosion scale was loose and prone to localized destruction which in turn presented pitting corrosion, while CO2 corrosion scale was compact and provided a high
