Antimicrobial and antifungal materials we prepared from Zn-containing wollastonite set by wet precipitation method. Wollastonite, hardystonite, willemite and very little quartz were developed after sintering at 1100°C/2h, however, the Raman spectroscopy approved the later phases by their characteristic Raman shift bands. The microstructure exhibited accumulated rounded to irregular clusters containing nano-size particles (E. coli) and Gram-positive (S. aureus & B. subtilis). Correspondingly, the CZS5 exhibits good inhibitory effect against the filamentous pathogenic fungus (A. niger). |
