hydrothermal conditions without an autoclave
« on: August 06, 2008, 01:09:12 PM »
Hi all..

Can someone tell me how to maintain hydrothermal conditions: 200-250 C without having to use a titanium autoclave to grow my metal oxide.

Also, what is a titanium ultrasonic horn?
Is there any alternative for a vacuum evaporator? Can a normal dessicator be used?

I appreciate your replies.

Metal oxides of titanium should grow in air at 200-300 C without any problems. I've never heard of titanium ultrasonic horn, but you may wish to fish through these results:

But the procedure requires me to use hydrothermal conditions to get the final results.
Any suggestions on vacuum evaporator?

Thanks

Depends what you need to do in a vacuum evaporator? Most labs have a vacuum pump, and it couldn't take more than a few hours to cobble together a sealed box to place samples to evaporate in.
