**碲酸鉀**是一種無機化合物，是鉀的碲酸鹽，化學式 K 
2TeO 
4

## 製備

碲酸鉀可以由二氧化碲和硝酸鉀反應而成。

## 性質

碲酸鉀是一種可溶於水的白色固體。

## 反應

和三氧化硫反應：

$$
{\mathsf {K_{2}TeO_{4}+SO_{3}\ {\xrightarrow {110^{o}C}}\ K_{2}SO_{4}+TeO_{3}}}
$$

和硝酸銀反應，形成碲酸銀：

$$
{\mathsf {AgNO_{3}+K_{2}TeO_{4}\ {\xrightarrow {T}}\ Ag_{2}TeO_{4}\downarrow +2\,KNO_{3}}}
$$
