Subsequently, the heat-treated powder was milled in a high-energy mill (PM 100, Retsch) at 400 rpm, using a mill and microspheres of zirconia (diameter 0.3 and 0.4 μm) for 1, 2, 3 h using alcohol isopropyl (Purity 99%, Quimidrol) as the solvent. Samples without high energy milling were also analysed for purposes and comparison.
The material, as received, was subjected to thermal treatment at 1100 °C for 2 h, under air atmosphere, to eliminate polymorphic forms, remaining only the monoclinic phase of the space group P2/m and also subjected to grinding in the high-energy mill, under air atmosphere for 1.5 h at 300 rpm, using a grinding vessel and zirconia spheres at a ...

1 Introduction. Formaldehyde (CH 2 O) is an important bulk chemical, as it is the smallest aldehyde and an important C 1-building block used for a variety of different products and processes. 1 The global production of formaldehyde is about 50 million metric tons of formalin, an aqueous solution of 37–57 wt% formaldehyde, per year. The market is expected to grow to 60 million tons per year ...
Nano-hydroxyapatite and its modification, hydroxyapatite with the excess of phosphorus (P-HAP) and hydroxyapatite with the carbon ions built into the structure (C-HAP), were prepared by the wet method. They were studied by means of XRD, accelerated surface area and porosimetry (ASAP), and SEM. The size of crystallites computed using the Scherrer method was nano-hydroxyapatite (HAP) = …

Abstract. Mechanochemical method was used to obtain nano-size hydroxyapatite/HA powder, both in wet and dry conditions, by using CaCO 3 and (NH 4)H 2 (PO 4) as starting materials.Nano-particles of HA were obtained by high energy ball milling in wet conditions having rotation speed of 600 rpm/10 h by taking ethanol as grinding liquid and zirconia balls as grinding media.
