Özet

Every ruby produced in the world is in different qualities with its unique characteristics. The development of ruby’s color is effective in annealing in different atmospheres. In our work, crystal parameters, spectroscopic properties and color changes were determined by heat-treating the newly discovered ruby in the nitrogen atmosphere in Turkey. The annealing result in the nitrogen atmosphere was: a-axis 0.17% and c-axis 0.25%, for R-3c: R-3c: R a-axis 7.06%, alpha angle 5.19% and a- 0.99, c-axis increased by 0.94%. After annealing, a large absorption peak was observed at a wavelength of 500 nm in the UV-Vis spectrometer. The red color of the ruby was white-light-pink after annealing. Heat treatment in the nitrogen environment caused a change in the color of the ruby.
