Application
碲与氢氧化钾结合，介导了芳香族羰基化合物的定量频哪化。
碲可用作制备以下物质的前体:
- 用于半导体应用的碲基纳米材料，如通过溶剂热合成制备的CdTe纳米颗粒。
- 用于荧光法测定生物活性化合物的量子点溶液。
- 热电材料，如通过熔融-淬灭-SPS方法制备的Cu4Mn2Te4。
General description
碲没有放射性，是硫族家族中最重的成员。 它的氧化态范围很宽，从-2至+6。它被广泛应用于 冶金和电子领域。

Despite being disparaged for their malodorous and toxic demeanour, compounds of selenium, a bio-essential element, and tellurium, offer possibilities as therapeutic agents. Herein, their potential use as drugs, for example, as anti-viral, anti-microbial, anti-inflammatory agents, etc., will be surveyed along
