The characteristics and quality of activated carbons prepared depending on the chemical and physical properties of the starting materials and the activation method used.
Introduction Activated carbons are produced from a variety of carbonaceous materials.
The quality and characteristics of activated carbons depend on the chemical and physical properties of the starting materials and the activation method used.
All the peaks present in this figure were similar to those found in the infrared spectra of raw materials (Fig.2).
Generally, the entire spectrum has high intensity of peak, similar to raw materials.

This is because the manufacture of cement, one of the main materials used in the production of concrete produces carbon dioxide.

The materials upon the point P were rise up along rake face.
In simultaneity, the materials below the point P were flowed towards to flank face and formed the machined faces. θ is the position angle of point P.
The rake force was generated mainly from three sources: the force of spring back of workpiece materials, the force of plastic formation of workpiece materials and the force of friction between chip and tool rake face.
