**一硫化矽**是一種無機化合物，化學式 SiS，為黃色無定形體。

## 製備

可以硫和矽以一比一摩爾在高溫下取得，但此反應會產生更多二硫化矽。

　
: ${\mathsf {Si+S\ {\xrightarrow {650-700^{o}C}}\ SiS}}$

此外亦可以讓矽與二硫化矽於 850℃反應、與二硫化碳於 1000℃反應或與硫化亞鐵於 1200℃反應。

## 性質

一硫化矽為亞穩態物質，在微量的水分下便會分解。其纖維狀形態比玻璃質形態更活躍，易受光照或熱而反應。大約 650℃以上時，歧化成二硫化矽和矽的速率會顯著增加。

　
: ${\mathsf {2SiS\ {\xrightarrow {650^{o}C}}\ SiS_{2}+Si}}$

在氣態時，其矽原子與硫原子的鍵長為 192.93 pm，較普遍單鍵的 216 pm 短，而且比一種有機矽化合物中雙鍵的 201 pm 短。

## 星際分子

在星際空間能探測到一硫化矽，尤其是在富含碳的恆星的星周包層。
