ZnO has received much attention due to its low cost and its demonstrated activity in several photochemical and photoelectrochemical process [214–216]. It has a band gap similar to TiO 2 (3.2 eV) [217] and possesses greater quantum efficiency [218]. ZnO has three different phases: wurtzite, zinc blende, and rock salt.
Fitzpatrick Hammer Mills produce the smaller PSDs and are more suited to abrasive and difficult to mill products. They are the mill of choice when you need to precisely control the particle size reduction process. It is important to get the feed throat angle matching the material characteristics - a vertical inlet for fragile material or horizontal for fine grinds.
This process is known as chemi-crystallization. 52 The results obtained by WAXD clearly indicate, according to the FTIR results, that ZnO delays the chemi-crystallization of iPP. Mechanical Properties
