Introduction Production of wrought titanium and Ti-6Al-4V alloy remains expensive and has, thus, limited the application of these materials to niche markets.
The objectives for the study are to show the effects of customised particle size distributions for a range of powder blends on the properties at each process step, and to relate the densification pathways to microstructure, material and mechanical properties.
The reduction in shrinkage, improved green and sintered densities would have beneficial effects on the material’s mechanical and microstructural properties.

Lignin was isolated from black liquor of pulp and paper with palm empty bunch materials.
Lignin can be isolated from black liquor of pulp and paper with palm empty bunch materials [2].
The other thing that also support the use of palm empty bunch is the prevailing program of ecolabelling in some of the develop country for the industries that use the materials from forest.
As the result, acacia that is used to be the materials of paper and pulp is started to be replaced by other biomass that contains cellulose, one of it is palm empty bunch.
