| 摘 要： | 引言用于鉴定矿物的折光率浸油,有液体浸油和固体浸油两类。在鉴定矿物过程中用液体浸油要比用固体浸油方便得多。因此人们在液体浸油所能达到的折光率范围內,都尽量地采用液体浸油而不用固体浸油。

| Abstract: | As2S3 and CH2I2 are put into a vessel, and then warmed to 145°—148℃ on the glycerine bath for a few minutes. The methylene iodide begins to dissolve the arsenic trisulphide slowly, and the liquid becomes gradually clear and red-brown in colour. The indices determined by means of goniometer are 1.74 to 2.25. |
