Study of the effect of milling parameters on mechanosynthesis of hydroxyfluorapatite using the Taguchi method

Mechanosynthesis of carbonate and lithium co-substituted hydroxyfluorapatite

“…2. The broad absorption bands in the 2500-3700 cm -1 range are assigned to the O-H stretching vibration [15], [16]. The IR spectra show all the bands associated to the phosphate groups (PO4) 3-in the apatite environment: asymmetric stretching (υ3) located around 1090 and 1041 cm -1 , symmetric stretching (υ1) around 963 cm -1 , symmetric bending (υ4) located between 600 and 560 cm -1 and asymmetric bending (υ2) around 473 cm -1 [13].…”

“…HFA and fluorapatite are also less soluble and more stable than hydroxyapatite [12]. Different synthesis methods have been used to prepare apatite: solid-solid reaction at high temperature [12], precipitation in an aqueous medium [13], hydrolysis by hydrothermal process [14], sol-gel [15] and mechanosynthesis [16]. The powder obtained by each of these methods has different crystallo-chemical and morphological characteristics.…”

Parametric Study on the Flow Profiles of Vertical Sinter Cooling Bed Using the DEM and Taguchi Method for Waste Heat Recovery

“…Therefore, the difficulty related to particle flow in sinter layers declines with a decrease in the magnitude of the shear rate when the discharge velocity accelerates. The Taguchi method provides the advantage of effectively minimizing the number of designs and consideration of full-factorial data to search for the optimal factor and level corresponding to the target response [27][28][29]. The design factors and their levels exhibit an orthogonal array arrangement in the factorial design experiment.…”

“…The Froude number (Fr) describes the evaluation criteria of the ability of smooth particle flow to solve the problem of particle transportation and ensure smooth particle flow during the gas-solid heat transfer process for enhancing the performance of heat transfer between sinter particles and air. The Froude number is defined as a formalization of the nonsquared symmetric device developed as follows [30,31] The Taguchi method provides the advantage of effectively minimizing the number of designs and consideration of full-factorial data to search for the optimal factor and level corresponding to the target response [27][28][29]. The design factors and their levels exhibit an orthogonal array arrangement in the factorial design experiment.…”
