Sandy alumina determination of physical performance Part 5. X- ray diffraction method α- alumina content1 ScopeThis section provides a method for determining X- ray diffraction sandy alumina content of the α-Al2O3. This section applies to the determination of sandy alumina content in α-Al2O3. Measuring range. ≤20.0%.2 Method summaryIn the same diffraction conditions were samples and standard samples (012) crystal face of the integrated intensity values measured in accordance with standard samples containing the α-Al2O3 The amount of the sample to calculate the content of α-Al2O3.3 Reagents3.1 high purity alumina (99.99%). 3.2 aluminum hydroxide. 3.3 ethanol. 3.4 corundum crucible (100mL).4 Instrument4.1 agate mortar. 4.2 X- ray diffraction. General Instrument stability better than 0.5%, work on indicators see Appendix A. 4.3 Oven. Maximum operating temperature 300 ℃ ± 5 ℃. 4.4 high-temperature furnace. maximum operating temperature of 1600 ℃ ± 5 ℃.5 Sample Preparation5.1 The high purity alumina (3.1) in 100mL corundum crucible (3.4) was packed to 2/3, at 1450 ℃ ± 20 ℃ baking after 6h The resulting alumina regarded as containing α-Al2O3 (100.0%). 5.2 aluminum hydroxide (3.2) placed in 100mL corundum crucible (3.4) was packed to 2/3, after 700 ℃ ± 20 ℃ baking 4h prepared Alumina deemed free of α-Al2O3. 5.3 A sample (5.1), (5.2) drying 2h at 105 ℃ ± 5 ℃, dubbed by the mass ratio α-Al2O3 content of 0,5.0%, 10.0%, respectively, 15.0%, 20.0% of the standard sample, and mix thoroughly ground to a particle size of less than 10μm.6 measuring step6.1 adjusting X diffractometer (4.2) to reach a steady state measurement requirements. ...... |
