Self-Propagating High-Temperature Synthesis of Zirconium ...
The synthesized zirconium-nitride sinters consisted of sintered particles of sizes 0.5 – 1 mm. Additional milling in a ball mill with a 10-L steel drum lined with tungsten carbide (TC6 alloy) plates produced a powder of the required particle size (<50 μm). The milling spheres (10 mm diameter) were made of tungsten carbide (TC8 alloy).
