Hi! I wish to design a heat pipe for high temperature (up to 1300 degree Celsius). What material can I use? What about aluminum powder? Thanks.

I'm not understanding what you want to do. I don't recognize your usage of the term "heat pipe" in this context and don't understand if you are talking about the material for the pipe or something going in the pipe.

Thank you very much! I wish to transfer the heat from one chamber to another speedily. I wish to know what is the material that I could use as the conducting agent (in the tube). The heat pipe I am going to use is at 1250 degree Celsius. Thanks.

For a heat pipe to operate, the fluid used in it has to be heated to it's boiling point. Since Aluminum's boiling point is 2519 degrees C, it won't work for the temperatures you're talking about.
