【Abstract】 The micro KTP crystal is synthesized by a high temperature solid state reaction.The characteris- tics of crystal’s morphology are exhibited by polarized light microscope and the phase of the sintering crystal is amply analyzed by XRD.The least-squares procedure is used to compute the cell parameters of the samples and analyze the re- lation of the cell parameters and the synthesized temperature.The KTP crystal is orthorhombic at 1000℃whose cell parameters are a₀=10.587（3）（?）,b₀=12.814（3）（?）,c₀=6.404（2）（?）and V=868.7（3）（?）.The standard deviation of dis- tance of nets between acture measure and computational value is 0.00335.It is showed that the KTP is a good crystal.更多还原
