[Developments of high temperature Raman spectroscopic techniques].

High temperature Raman spectroscopy (HTRS) is contemporarily a useful tool to study micro-structure of various materials under high temperature. Developments of HTRS techniques are well reviewed. In order to realize the determinations of metallurgical melts, the modified instrumentation for high temperature determination purpose based on JY U1000 Raman spectrometer in Shanghai Enhanced Lab of Ferrometallurgy (SELF) is introduced. It is assembled as macro-Raman with time-resolved detect system by using pulsed Copper Vapor Laser(CVL). This is the first set of its kind in domestic and some further modifications are proposed.
