5. Phosphorus Extraction ChestofBooks

Phosphorus is extracted from calcined bones, which have been heated to the red heat in contact with the air, so as completely to destroy the organic matter. This combustion can easily be made in a lime-kiln. This kiln is surmounted with a reverse cone, terminated by a pipe, more or less long, so that the gases can be directed into a chimney.

Bone ash Wikipedia

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 depending 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

Bone Ash Digitalfire

Notes. Bone ash is TriCalcium Phosphate in the form of Hydroxyapatite Ca5(OH)(PO 4)3.This reacts when making bone china to give Anorthite (CaAl 2 Si 2 O 8) and Ca3(PO 4)2. 2*Ca5(OH)(PO 4)3 --> 3*Ca3(PO 4)2 + Ca(OH)2 Real bone ash is obtained by calcining bone up to approximately 1100°C and then cooling and milling.

ANALYSIS OF ASH AND MINERALS UMass

4. Analysis of Ash and Minerals . 4.1 Introduction. The “ash content” is a measure of the total amount of minerals present within a food, whereas the “mineral content” is a measure of the amount of specific inorganic components present within a food, such as Ca, Na, K and Cl.Determination of the ash and mineral content of foods is important for a number of reasons:

Chemical phosphorus recovery from waste fish bones ash by

The phosphorus content in the fish bone ash represents around 17 wt.%. The potential of phosphorus recovery from waste fish bone ash by chemical dissolution was investigated in this study. Different amounts and concentrations of sulfuric acid (H2SO4) was applied to determine the optimum condition of phosphorus extraction.

Mar 01, 2003· The R2 for g bone ash is much higher than for % bone ash (0.918 vs. 0.568; Table 4). The variability in weight of the bone ash is mainly attributable to day, phytase level, and method R2 = 0.918), but other bone components left after water and lipid removal (organic matrix) must not be attributable to these factors.

Mapping genes for phosphorus utilization and correlated

A large F2 cross with 920 Japanese quail was used to map QTL for phosphorus utilization, calcium utilization, feed per gain and body weight gain. In addition, four bone ash traits were included, because it is known that they are genetically correlated with the focal trait of phosphorus utilization.
