摘要
This invention is within the technical field of corundum appraisal, and it involves an examination method to determine whether corundum has undergone beryllium diffusion treatment. Procedurally, a highly sensitive Raman spectrometer (S/N10,000) is used to scan and examine the samples. The spectrometer is fitted with a tailor-made probe having a large facula and surface area. Specially developed software is then used to perform an intensity correction and a background elimination to obtain a specific Raman spectral range (250-120 cm-1) with the corrected intensity and a smooth baseline. The corrected and standardized Raman characteristic peak at 804 cm-1 (side-band) is used as a basis to determine whether the corundum has undergone beryllium diffusion treatment. This invention method has the advantages of being non-destructive, simple, fast, and practical. Also, it can accurately determine whether corundum has been treated.
