活性炭 Activated carbon
（重定向自Active coal）
活性炭（Active charcoal），亦称活性碳（Active carbon）、活化炭（Activated charcoal; Activated char）或活化碳（Activated carbon），是黑色粉末状或颗粒状的碳物质。活性炭在结构上由于微晶碳是不规则排列，在交叉连接之间有细孔，在活化时会产生碳组织缺陷，因此它是一种多孔碳，堆积密度低，比表面积大，也是做一个过滤器的主要物料。

![A micrograph of activated charcoal (R 1) under bright field illumination on a light microscope. Notice the fractal-like shape of the particles hinting at their enormous surface area. Each particle in this image, despite being only around 0.1 mm across, has a surface area of several square meters.[13] The entire image covers a region of approximately 1.1 by 0.7 mm, and the full resolution version is at a scale of 6.236 pixels/μm.](/uploads/202412/20/ActivatedCharcoalPowder_BrightField1533.jpg)
Activated carbon, also called activated charcoal, or activated coal, is a form of carbon processed to have small, low-volume pores that increase the surface area available for adsorption or chemical reactions. Activated is sometimes substituted with active.
