Hello, the last time you gave me the answer on the silicon chip let me learn a lot, I would like to ask here, sapphire crystal density you know?
Mohs hardness: 9.Density: 4 (+0.10, 0.05) g/cm 3.Optical characteristics: inhomogeneous body, one axis crystal, negative light.Color: strong. Blue: blue, green and blue; green: green, yellow and green; yellow: yellow, orange, orange orange; orange; pink: pink, purple, purple, purple and pink.Refractive index: 1.762 ~ 1.770 (+0.009, 0.005).Birefringence: 0.008 ~ 0.010.Ultraviolet fluorescence: Blue: long: no Xeon, orange; HF: no to weak, orange.Pink: long: strong, weak, orange orange; short wave.Orange: No, long wave strong, orange.Yellow: long: no to, red orange, orange red to orange: weak short wave.Color: purple, long wave: no Xeon, red; HF: no to weak, red.Colorless: no to medium, red to orange.
Mineral name: corundum.Hard brittle materialChemical composition: Al 2 O 3; can contain Fe, Ti, Cr, V, Mn and other elements.Crystalline state.Crystal system: three party system;
I'm sorry, I really know that. The composition of sapphire is alumina.This is the information I found on the Internet to help you.SapphireEnglish Name: sapphire.
