[Analytical studies on calcium and microelements in calcined longgu (an animal bone)].
The main constituent (CaCO3) and microelements of Longgu (an animal bone) have been analysed qualitatively and quantitatively by orthogonal design. The result shows that the optimum conditions for calcining Longgu are: temperature--750 degrees C, time--4'30'', size of the bone--8.5g.
