原始语种摘要: Abstract(#br)Single crystals of ruby have been obtained from fluxed melts based on the systems Li 2 O–MoO 3 , Li 2 O–WO 3 , Na 2 O–WO 3 , 2PbO–3V 2 O 5 , PbO–V 2 O 5 –WO 3 , PbF 2 –Bi 2 O 3 and Na 3 AlF 6 by both the TSSG method and spontaneous crystallization at the temperatures 1330–900°C. Al 2 O 3 solubility has been measured for the flux composition of 2Bi 2 O 3 –5PbF 2 in the temperature range 1200–1000°C and dissolution enthalpy has been defined as 29.4KJ/Mol. The composition of grown crystals was studied by electron microprobe analysis. The synthetic ruby contains from 0.51 to 6.38at% of chromium admixture depending on the crystal growth conditions. Experimental results on growth conditions, composition and...
