Calcium orthophosphates (CaPO4): Occurrence and properties

The present overview is intended to point the readers' attention to the important subject of calcium orthophosphates (CaPO 4).This type of materials is of the special significance for the human beings because they represent the inorganic part of major normal (bones, teeth and antlers) and pathological (those appearing due to various …

Transfection maximizer increases the efficiency of calcium

To improve the utility of CaPO4 transfections, we have identified a transfection enhancer (CalPhos Maximizer) that dramatically increases the efficiency of CaPO4 transfections with mammalian cells. The CalPhos Maximizer is a cellular structural protein that improved CaPO4 transfections with all mammalian cell lines tested and yielded greater ...

Functionalized calcium orthophosphates (CaPO4) and their …

Due to the chemical similarity to natural calcified tissues (bones and teeth) of mammals, calcium orthophosphates (abbreviated as CaPO 4) appear to be good biomaterials for creation of artificial bone grafts.However, CaPO 4 alone have some restrictions, which limit their biomedical applications. Various ways have been developed to improve the …

Recover Hydrofluoric Acid from Fluosilicic Acid Waste

Hydrolysis of Lime-Neutralized H2SiF6. Preliminary tests, not described, established that hydrolysis took place when steam was passed through a bed of lime-neutralized H2SiF6 at about 1,000° C. The chemical reactions of lime neutralization may be expressed by the following: Neutralization of H2SiF6 with calcium hydroxide (Ca(OH)2) …

Since Hexafluorosilicic acid doesn´t exist in anhydrous form it

analyzing H2SiF6 is the EN standard 12175 in which equilibriums are displaced in order to express the composition as H2SiF6 and the excess of fluorides expressed as HF, but it doesn´t mean "free HF" exists as itself. It is only a way of expressing the results obtained in the analytical method which is not specific for determining HF.
