Combination of Autoclave Treatment and NDIR Process Analytics for Quantification of Aluminum Carbide in Powdery Samples

Aluminum Carbide (Al4C3) is a main source of corrosion problems in metal matrix composites as well refractory products. Hydrolysis to methane happening at room temperature leads various structural problems. As methods quantify Al4C3 are scarce, this paper proposes method measure containing analyte powders mg areas by combining robust autoclave system with non-dispersive infrared (NDIR) process analytics. The uses only water reagent, making it easy and safe handle. used materials were characterized thermogravimetric analysis coupled fourier-transformation detection (TGA-IR), LECO-C analysis, X-ray diffraction (XRD) before after treatment. 90–90.8% recovery 100 small standard deviations (<1% n = 3) 240, 205, 165 min 60, 70, 80 °C, respectively, achieved. XRD showed the total conversion Bayerite (Al(OH)3) Boehmite (AlO(OH)) 70 °C. Comparison shrinking core models that reaction neither purely nor ash diffusion controlled. findings indicate possibilities for further acceleration speeds increasing temperature. 200 mL reactor volume enables bigger sample sizes temperatures above °C separating procedure. This provides an extension gas chromatographic industrial quality control bulk rougher environments.
