Tricalcium phosphate (sometimes abbreviated TCP), more commonly known as Calcium phosphate, is a calcium salt of phosphoric acid with the chemical formula Ca 3 (PO 4) 2. It is also known as tribasic calcium phosphate and bone phosphate of lime ( BPL ).
The tricalcium phosphate in bone char can be used to remove fluoride [3] and metal ions from water, making it useful for the treatment of drinking supplies. Bone charcoal is the oldest known water defluoridation agent and was widely used in the United States from the 1940s through to the 1960s. [4]
An anticaking agent in salt is denoted in the ingredients, for example, as "anti-caking agent (554)", which is sodium aluminosilicate.This product is present in many commercial table salts as well as dried milk, egg mixes, sugar products, flours and spices.
Calcium phosphate stones account for approximately 15% of kidney stone disease. Calcium phosphate stones tend to grow in alkaline urine, especially when Proteus bacteria are present. It is the most common type in pregnant women. [6] Calcium phosphate is the usual constitution of microcalcifications of the breast, particularly dystrophic ...
Amorphous calcium phosphate (ACP) is a glassy solid that is formed from the chemical decomposition of a mixture of dissolved phosphate and calcium salts (e.g. (NH 4) 2 HPO 4 + Ca(NO 3) 2). The resulting amorphous mixture consists mostly of calcium and phosphate, but also contains varying amounts of water and hydrogen and hydroxide ions ...
Phosphate-free detergents are sold as eco-friendly detergents. In the 21st century phosphates began to be reduced in percentage terms as an ingredient, leading to a New York Times report that said "low- or phosphate-free dishwasher detergents it tested, including those from environmentally friendly product lines that have been on the market for ...
It usually contains between 2% and 5% of an anti-caking agent—such as corn starch, potato starch or tricalcium phosphate [1] [2] —to absorb moisture, prevent clumping, and improve flow. Although most often produced in a factory, a proxy for powdered sugar can be made by processing ordinary granulated sugar in a coffee grinder , or by ...
Since the 1990s, the use of synthetic alternatives to bone ash, which are based on dicalcium phosphate and tricalcium phosphate, has increased. Significant amounts of bone china is produced using these synthetic alternatives rather than bone ash. [4]
