Dear Sir/Madam, This is DONHANSEN from US. I'm looking for products with the following specifications: I have a different purpose then for ceramic targets about 5 diameter. I have my own design for my part and was wondering if you could make custom parts for me? I want the manufacturer to tell me what is the best target material that can be in water with electricity and not be destroyed. What is the best electricity conductive materials and the best heat conductive materials also? There is diamond that can do both conduct heat and conduct electricity, such as boron doped diamond. Are there other diamond types that can be used and is the ppm 300 or greater in doping the diamond? Trying to figure out the best ratio of mixing materials also and could use some help in that. I need to know that I can trust your materials and what you say will be in them and the conductivity will be reproducible and you can duplicate the parts accurately. Thank you, Don Show More
