ACP is a unique calcium phosphate in that it lacks long-range crystalline order. Yet the constancy in the composition of ACP over a wide range of solution conditions suggests a well-defined local structural unit. Although this order within disorder is the most distinguishing feature of ACP, the solution instability of ACP and its ready transformation ...

Amorphous calcium phosphate (ACP) in tissue repair process
Microscopy Research and Technique, 2018AbstractSynthetic biomaterials submitted to new structural technologies have become ideal for the recovery of traumatized bone tissues and some bone substitutes such as bioactive glass, β‐Tricalcium phosphate (β‐TCP) and amorphous calcium phosphate (ACP) are being used in areas of tissue defects.

Novel microwave synthesis of amorphous calcium phosphate nanospheres
Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2012AbstractAmorphous calcium phosphate (ACP) is an important precursor phase in tissue mineralization. It shows high solubility and excellent remineralization ability. Commercially viable techniques for producing ACP are high‐cost/low‐efficiency process.

Synthesis of Amorphous Calcium Phosphate: A Review
Key Engineering Materials, 2020The aim of this study is to summarize various synthesis routes of amorphous calcium phosphate (ACP), focusing on properties, especially Ca/P molar ratio and specific surface area (SSA) of obtained ACP. The effects of synthesis conditions on properties of final products are analysed and discussed.

Amorphous Calcium Phosphates (ACP): Formation and Stability
Key Engineering Materials, 2005Our earlier studies showed that several ions inhibit the crystal growth of apatite and promote the formation of amorphous calcium phosphates (ACP). These ions include: magnesium (Mg), zinc (Zn), stannous (Sn), ferrous (Fe), carbonate (CO3), pyrophosphate (P2O7). The purpose of this study was to investigate the effect of combination of these ions (e.g.,

Temperature programmed dehydration of amorphous calcium phosphate
Journal of Colloid and Interface Science, 1974Abstract The kinetics of dehydration of amorphous calcium phosphate (ACP) has been studied by the temperature programmed desorption technique (TPD) of Cvetanovic and Amenomiya. Each water desorption spectrum for ACP exhibited a single, but fairly narrow, peak.

Dental applications of amorphous calcium phosphates.
The Journal of clinical dentistry, 2000Certain commercial materials and equipment are identified in this paper to specify the experimental procedure. In no instance does such identification imply recognition or endorsement by the National Institute of Standards and Technology or the ADA Health Foundation, or that the material or equipment identified is necessarily the best available for the

Amorphous calcium phosphates for tooth mineralization.
Compendium of continuing education in dentistry (Jamesburg, N.J. : 1995), 2005The destruction of tooth structure through caries and erosive processes is due to two types of acidic challenges that affect the tooth in different ways. Acidic attack by cariogenic bacteria initially produces subsurface lesions that weaken the enamel and, if left unchecked, can progress through the enamel and dentin and eventually into the pulpal ...

Calcium metal to synthesize amorphous or cryptocrystalline calcium phosphates
Materials Science and Engineering: C, 2012Abstract Metallic calcium was never used before as the calcium source in synthesizing bioceramics. Amorphous calcium phosphate (ACP) powders were synthesized at room temperature, in synthetic mineralization solutions which contained Na+, K+, Mg2 +, Cl−, HCO3− and HPO42 − ions at concentrations similar to those found in human blood plasma, by using ...
