Making of Bone Char

[jerryyu]

A lot of people told me that you should heat the cattle bones first and then ground it in a mortar and sieve to obtain a small size. But does it matter if you ground it first or heat it first?

It was earlier event.

Heat it first is right.

First you do carbonization process. The carbonization process should be done in the no air condition.

Then do activation process. At this step small pore is developed, and the meso-pore is also developed.

Finally ground the char into proper particle size you need.

In the past bone char is used for decolorization of the cane sugar. The liquid adsorption process is required the bone char which has developed meso-pore.

But could you ground it first and then do the charring process?

one more question, is the carbonization process not only take water water out of the bones but also the inorganic substances? and leaving only carbon behind? s

even if we burn all the water out, the carbonization process will still not be complete?
