Bone ash
is a white material produced by the
calcination
of
bones
. Typical bone ash consists of about 55.82%
calcium oxide
, 42.39%
phosphorus pentoxide
, and 1.79%
water
. The exact composition of these compounds varies upon the type of bones being used, but generally the formula for bone ash is: Ca
5
(OH)(PO
4
)
3
. Bone ash usually has a
density
around 3.10 g/mL and a
melting point
of 1670°C (3038°F). Most bones retain their cellular structure through calcination.
Uses
Bone ash has many uses, such as in fertilizers, polishing
compounds
, or the production of
bone china
. In addition, bone ash can be used as a protective coating for metal equipment, tools, or around a floor as moulding. In this context, bone ash is well established as a sealant for seams or cracks.
As a powder coating, bone ash has many unique characteristics. First of all, the powder has high
thermal stability
, so it maintains its form in extremely high temperatures. The powder coating itself adheres to
metal
well and does not drip, run, cause much
corrosion
, or create noticeable streaks. Using the bone ash is easy as well, as it comes in a powder form, is easy to clean up, and does not separate into smaller parts (therefore requiring no extra mixing).
The raw material for
bone china
is about 50% bone ash derived from animal bones. These bones undergo multiple processing stages during which all meat is removed and the bone is completely cleaned. Once cleaned, the bone is heated to about 1000°C (1832°F) so that all additional
organic
material is removed from the bone and the bone becomes
sterilized
. Lastly, the newly sterilized bone is ground with water into fine particles which can be used as a raw material for bone china. Bone ash plays an important role in the creation of bone china, as the
phosphate
of the bone generates beta
tricalcium phosphate
, and other compounds from the bone create a calcium crystal called
anorthite
. Synthetic alternatives
dicalcium phosphate
and tricalcium phosphate are used as substitutes for bone ash. Most bone china are produced with synthetic alternatives rather than bone ash.

Bone ash can be used alone as a fertilizer or it can be treated with
sulfuric acid
, which ultimately allows the fertilizer to permeate the
soil
better. In addition to the
nutrients
to be found in the bone ash, the fact that the ash is dry and finely powdered makes it an excellent plant fertilizer.
