Effects of Milling Atmosphere and Increasing

Abstract. Nanocrystalline Ni 0.36 Zn 0.64 Fe 2 O 4 was synthesized by milling a powder mixture of Zn, NiO, and Fe 2 O 3 in a high-energy ball mill for 30 h under three different atmospheres of air, argon, and oxygen. After sintering the 30 h milled samples at 500°C, the XRD patterns suggested the formation of a single phase of Ni-Zn ferrite.

Powder metallurgy – basics applications

• Milling can be dry milling or wet milling. In dry milling, about 25 vol% of powder is added along with about 1 wt% of a lubricant such as stearic or oleic acid. For wet milling, 30-40 vol% of powder with 1 wt% of dispersing agent such as water, alcohol or hexane is employed. • Optimum diameter of the mill for grinding powders is about 250 mm
