碲化鋅的製備方法和硒化鋅類似，有干法和濕法兩種。干法是將單質碲和鋅在氫氣氣氛中加熱（如果在空氣中反應，則會氧化），產物升華，得到紅棕色的碲化鋅[2]：
- Zn + Te → ZnTe
濕法是用碲化鈉和乙酸鋅在水溶液中反應，產物是黃棕色的水合物沉澱：
- Na2Te + Zn(CH3COO)2 → 2 CH3COONa + ZnTe（水合）↓
碲化鋅遇到酸放出劇毒的H2Te氣體：
- ZnTe + 2 H+ → Zn2+ + H2Te↑
碲化鋅可以被空氣中的氧氣氧化，反應條件不同，產物不同：
- 2 ZnTe + O2 → 2 ZnO + 2 Te
- 2 ZnTe + 3 O2 → 2 ZnO + 2 TeO2
