Methods are disclosed for producing a calcium phosphate salt comprising reacting fluorosilicic acid (FSA) with water and a calcium phosphate source to produce phosphoric acid, calcium fluoride, and silicon dioxide; removing residual solids; performing a first stage precipitation wherein the phosphoric acid generated previously is reacted with a calcium source and water to remove residual fluoride; and performing a second stage precipitation wherein the phosphoric acid generated previously is reacted with a calcium source and water to isolate the product calcium phosphate salt, having a low level of impurities.

This invention relates to strontium-phosphate microparticles that incorporate radioisotopes for radiation therapy and imaging.

A method of producing ammonium phosphates from at least one mineral containing phosphate and an element which is calcium, magnesium, iron, or aluminum. The method includes contacting the at least one mineral (or a combination of them) with a cation exchanger for a time and at a temperature sufficient to yield phosphoric acid from the mineral.

This invention newly describes fast and reliable creation of three-dimensional scaffolds using magnetic levitation of calcium phosphate particles. In particular, tricalcium phosphate particles of similar size and specific porosity are used which are subjected to recrystallization process after magnetic levitation assembly of the scaffold to ensure scaffold cross-linking. Levitation assembly without marks is reached by using specially developed magnetic system in the presence of gadolinium salts which allows levitation of calcium phosphate particles. Chemical synthesis of octacalcium phosphate in magnetic levitation conditions in non-homogeneous magnetic field was also demonstrated. Such approach allows to obtain phosphate phase quickly in biocompatible finished product.

To provide a method for producing a porous calcium phosphate body having open micro-pores, by the method for producing the porous calcium phosphate body, in which calcium phosphate is subjected to electro-spinning.

An apatite for a filler includes an apatite that contains metal. The metal entirely or partially replaces the calcium of the apatite. A filler composition includes the apatite and hyaluronic acid. The metal may be magnesium (Mg), zinc (Zn), and/or strontium (Sr). The metal of the apatite replaces the calcium of the apatite in a solution using a laser.
