| 摘要: |
| 利用水热法合成出数粒块状红宝石晶体,其颜色为略带玫瑰的鲜红色,最大尺寸为50mm×17mm×15mm。籽晶切向以(2243)为主、以Cr2O3为致色主要化合物。水热红宝石的晶体结构、化学成分及其它宝石学特点均同天然红宝石相似,但水热法合成红宝石Cr2O3含量明显偏低于天然红宝石,此外V2O5的含量也较低。红宝石的水热生长试验在密封贵金属衬管中进行。使用自行设计制造的反应腔尺寸为∅38mm×700mm的高压釜及温差井式电阻炉;釜内温度500℃~600℃,晶体生长区(低温区)与溶解区(高温区)的温差30℃~80℃;釜内压力1500atm~2000atm;釜内开孔档板使用贵金属,开孔率5%~25%。介质溶液为钾钠的复杂碱性混合溶液,并掺入一定量的矿化离子(矿化剂)。 |

| Abstract: |
| Synthetic ruby crystals with pinkish-red color are produced by hydrothermal method. The maximum size of crystals with seed slice cut in the direction of n (2243) are 50 mm×17 mm×15 mm. Chromium oxide is dominant color-causing compound. Crystal structure, chemical composition and other gemological properties of hydrothermal rubies are similar to that of natural rubies, Cr2O3 percentage is clearly lower than that of natural rubies as for the V2O5 is a little lower than the natural one's.An experiment on hydrothermal growth are in process in a sealed tube with a precious metal liner.In a self-made reaction chamber,an autoclave with a size ∅38 mm×700 mm and a thermal resister furnace.The temperature range in the autoclave is 500℃ to 600℃,the temperature difference between crystal growth zone(Low temperature zone) and dissolving zone (High temperature zone) is 30℃ to 80℃,Pressure ranges from 1500 atm to 2000 atm,in the autoclave a precious metal porous baffle with a porosity of 5% to 25%.The medium solution is a complex alkaline solution of sodium carbonates and potassium carbonates containing some necessary mineralizing ions. |
