Want a material for Hydrofluoric Acid Heat Exchangers that is transparent to microwaves

I am currently looking into alternatives to a graphite block heat exchanger we currently use to heat hydrofluoric acid (also contains sulfuric acid and water). I was wondering about the newest microwave technology but I have been told that there is not a material that can withstand the corrosive properties and allow microwave energy to pass through. Do you know if there is such a material?

If not, what other options would be good for heating such a process mixture containing mostly hydrofluoric acid at a high flow rate? Thanks

Maybe you could benefit from a double walled plastic tank with hot water pumped between them. Depends on how hot you need it to be.

First of two simultaneous responses --

We are currently using steam on our graphite block heat exchanger with cold inlet temperatures near 210 degrees fahrenheit and hot outlet at 265 ° F, roughly.

PTFE heaters, thermostats and heat exchangers are all readily available. I don't know the US suppliers but any local metal finishing shop can give you a lead or look at adverts in the finishing periodicals.

You can try out with acrylic make heat exchanger.
