The manufacturing process should be capable of reducing production cost, material cost, and overhead cost.
The manufacturing process also needs to involve reliable delivery of products and materials.

Materials and methods Dense materials were obtained in disc shapes by uniaxially pressing green powders (< 75 µm) at 180 MPa, followed by sintering at 1200 ºC.
Sintering temperature was 100 ºC higher for porous materials, in order to increase mechanical strength.

Introduction Mg-based alloys have been considered as attractive hydrogen storage materials because of their high hydrogen capacity, light weight and low cost.
However, the slow desorption kinetics and high thermodynamic stability of the materials restrict them to actual applications.
Experimental High-pure elemental powders of Mg, Ni, Ti and Al were used as starting materials.

Introduction ABO3 perovskite consists of various materials depend on the application, namely, based-titanium, based-ferrite, or based-manganite [1-3].
The recent has be studied an electromagnetic wave absorber materials that developed by a materials of ABO3 perovskite composition based-manganite [4].
The magnetic structure of based-manganite materials depend on the forming of raw materials.
The three of raw materials are mixed by using a high-energy milling (HEM) type Spex 8000 for 10 hours at room temperature.
