Cost of Titanium Precursors Precursor Cost ($/lb) Cost of Contained Ti ($/lb) TiO *2 1.75 2.94 TiCl4 1.00 4.00 Ti Sponge 5.44 5.44 * Metal grade The approaches mentioned by Kraft are shown in Table IV, of these four appear to have the greatest potential for scale-up, with an additional process being developed by Advanced Materials (ADMA) Products also of potential commercial interest.
PRIMARY FABRICATION In the melting arena, plasma arc melting (PAM) and electron beam melting (EBM) are cold hearth melting processes that provide the advantage of flexibility using various forms of low-cost input materials, leading to reduced costs (6,7).

Another important difficulty regarding the contact problem is that its behaviour is always dependent upon the involved materials, the surface texture, the topology, loading rate, the amount of applied load, the load direction, boundary conditions, among others.
Therefore, this formulation is applied to analysis of contact among interfaces of different materials that compose a structural system.

Introduction Silicon carbide ceramics have been widely used as refractory materials, abrasives, and materials for commercial cutting tools.
SiC powder having an average particle diameter of 1 µm and a purity of 99.0% or greater and C powder having an average particle diameter of 0.3 µm and a purity of 99.98% or greater were used as the raw materials.
As a result, the crystal structure obtained was consistent with the SiC powder used as a raw material.
