Preparation of Porous Wollastonite Microspheres

Abstract:

Article Preview

Novel porous wollastonite microspheres for releasing silicate and calcium ions were prepared by electrospraying using a hydrolyzed alkoxide. Wollastonite formed in the microspheres by heating the electrosprayed precursor microspheres at 850 °C for 2 h. Numerous pores of 100-300 nm in diameter were newly formed at the surface of the microspheres. The size of porous wollastonite microspheres was determined to be 1-5 µm in diameter.
