Although iron powder and graphite powder are black powder, their other physical properties are quite different. For example, iron powder can be attracted by a magnet while graphite cannot, graphite powder has a slippery, the density of graphite powder is smaller than iron powder, etc.

The following two methods for rapid identification of graphite powder and iron powder are described:

Physical method to distinguish graphite powder and iron powder

1、You can take the method of touch, graphite powder has a greasy feeling, iron powder does not.

2, You can be attracted by magnets, iron powder can be attracted by magnets, graphite powder can not.

3. When heated, the iron powder turns black and the graphite powder is ignited in the air.

二、 The chemical method to distinguish graphite powder and iron powder

1, By chemical method, add dilute hydrochloric acid or dilute sulfuric acid, there are bubbles for iron powder.

2. Mix them with copper oxide and heat them respectively. Add the graphite powder to generate CO2 which makes the clarified limestone water cloudy.

The above are the two methods of quickly identifying graphite powder and iron powder summarized by Tianshengda graphite Co.,Ltd.
