I have 6 different powder samples of Mechanically Alloyed magnetic High Entropy Alloy Powders as FeCoNiAlMn1-xCrx (x=0,0.2,0.4,0.6,0.8,1). I need to measure there microwave absorption properties of my samples through Vector Network Analyzer so for that I need to make Torodial shape sample of my powders but unfortunately every time I try to make its breaks. So I need to know how to sort this problem. What adhesion can be add so that it doesn't break or how much pressure can be applied that can make Torodial sample without breaking. Inner diameter of Torodial sample required is approximately 3mm and its outer diameter approximately 7mm with 2-3mm thickness approximately.
Best Regards.
