Zirconium tribromide

Zirconium tribromide also reacted in liquid ammonia to give a dark brown precipitate and a similar colored solution (25). Addition of potassium amide resulted in the formation of additional precipitate and blue solution. The precipitate as finally recovered from the solution w as black, and had the composition Zr N K (1.00 3.25 1.69). The presence of the blue color was taken to indicate the reduction of potassium ion to the metal and oxidation of the zirconium to the four state with the formation of ammonolyzed products.

Newnham and Watts 391) were successful in producing high-purity zirconium trichloride, tribromide, and triiodide from the corresponding tetrahalides by atomic hydrogen reduction in a glow discharge tube. A yield of about 0.5 gm/hour was obtained. The product was separated from unreacted tetrahalide by sublimation at 200°C for the chloride and bromide, and 260°C for the iodide under reduced pressure. Careful control of flow rates, temperature, and electrode design are required for the successful operation of this process.
