Nano-sized boehmites with different crystallinity were synthesized at the temperature range of 25 to 200°C in order to produce phosphate absorbents with high capacity. The physicochemical property of boehmites was depended on the synthesis temperatu

Zeolite A whose surface was evenly covered with tiny scaly calcium deficient hydroxyapatite (Ca-def HA) nanocrystals was prepared through the ion exchange reaction of ammonium and calcium ions as a novel encapsulation material for the long-term immob

Highly crystalline Ca-Al layered double hydroxides (LDH) covered with needle-like hydroxyapatite (HA) nanocrystals was prepared from Ca-Al-Cl LDH by an alkaline treatment at 40°C using a Na 3 PO 4 solution at pH 9.0. The HA nanocrystals had lengths

Divalent cation-substituted α-phase tricalcium phosphates (α-Ca3-xMx(PO4)2, where M = Mg, Zn, Sr, Ba) were obtained by heating at 1500 °C for M=Mg (x = 0.03), 1400 °C for the others (x = 0.09), respectively. The resulting products were characteri

A new mica/polyamide 6 (PA6) nanocomposite was formed by exfoliation of a mica, potassium sericite (K + -SE). The powder sample was separated through an air-classifier into D 50 :6.0 μm (median particle diameter), D 10 :3.5 μm, and D 90 :9.5 μm. T

Crystalline layer-structured octacalcium phosphate (Ca8(HPO4)2(PO4)4 5H2O, OCP) and brushite (CaHPO4 2H2O, DCPD) were mechanochemically ground. The crystalline XRD pattern of OCP was weakened with grinding and reached almost amorphously after 72 h. H

Chlorinated TiO2 powders of high crystallinity and good dispersion have been synthesized via one-step Ar/O2 radio frequency thermal plasma oxidation of atomized aqueous solutions of TiCl3. The resultant powders are anatase/rutile mixtures (∼66−72
