| ABSTRACT |
|
Single crystals of kalsilite were synthesized by hydrothermal method at 420$^{circ}C$-480$^{circ}C$ and 100 atm-1500 atm. The crystal habits are similar to those of KLiSiO4 single crystals. The crystal structure was investigated by means of X-ray single crystal diffraction. The space group of kalsilite is P63. Phase transitiions were determined by use of DTA and high temperature X-ray Guinier camera. Phase transitions of kalsilite are summerized and discussed. |
