[Study on the economical, simple and convenient infrared airtight pool].

Monitoring and controlling the quality of the titanium tetrachloride and sponge titanium by the infrared spectrum is the best and quickest method. But the titanium tetrachloride is easy to hydrolyze, the product of hydrolysis will rust the instrument and pollute the surroundings. So the infrared pool must be airtight. We devise an infrared pool that its airtight nature is good, it is not only easy to clear, but also can be used repeatedly. This infrared pool can be fit the above mentioned requests. When we use it to determine some impurities in the titanium tetrachloride good results have been obtained. This experiment will make easy to monitor and control the quality of the titanium tetrachloride and sponge titanium.
