Alhiwi initial blue.
Resides on the basis of sapphire blue color purity primary passion. The colors are purple, violet and green are the tones of secondary natural in sapphire blue. [4] can be violet participate and purple in the beauty of color, while the green color is a negative color. [4] It is said about the sapphire blue inside with violet or purple by not more than 15% because of good quality. [4] But when sapphire blue mixed with any amount of degrees of green following their secondary color is not considered good quality. [4] The gray color is natural net or mask the color found in the Blue Sapphire rate . [4] Fallon gray reduces the net or the brightness of the color hue, and therefore have a negative effect is obvious.
Sapphire is red corundum that contains chromium impurities that absorb light greenish-yellow and the resulting dark red color of sapphire with increasing content. [5] The purple sapphire contains trace amounts of vanadium and come in a variety of shades. And corundum that contains a proportion of ~ 0.01% of the titanium is colorless. If there was trace amounts of iron are present, you can see the yellow color is very pale Alokhaddr.ouma slant to it when it meets both the titanium and iron impurities, the result is a very dark blue color in the extravaganza.
Unlike the local absorption of light (interatomic), which causes the color chromium and vanadium impurities, the blue sapphire comes from the transfer of valence charge, which is a transfer of an electron from the metal ion in the case of a transition to another by conduction or valence level. Iron can take formula Fe2 + or Fe3 +, while the titanium general formula takes Ti4 +. If replacement of the ions Fe2 + and Ti4 + ions of Al3 +, are creating areas endemic to the lack of balance of the shipment. It can cause electron transfer from Fe2 + and Ti4 + to change in the valence state of each of the parity change Alatnin.obsbb there is a certain change in the electron energy, and energy is Alkahromagnatisah.oakabl absorption wavelength of the absorbed energy Alocefr.uandma put this light color of white light falling , blue Altkamila.oahaana is produced when the atomic distances vary in different directions. The result dichroism greenish blue....
