ZrO2 + 2C + 2Br2 (560°C) → ZrBr4 + 2CO
Zirconium(IV) tetrabromide may be made through the direct reaction of the elements or by passing a stream of bromine in carbon dioxide over a mixture of zirconium(IV) oxide and sugar charcoal contained in a hot pyrex tube. Purification may be achieved by vacuum sublimation. The overall yield is about 60%. Zirconium(IV) bromide is a white crystalline solid that hydrolyses when dissolved in water.
