Hypothesis of the Study The bulk of metallurgical silicon production obtained in Russia is currently carried out in ore-thermal furnaces from silica-containing raw materials, by reducing silicon with carbon materials (charcoal, petroleum coke, coal and wood chips).
Laser diffraction is the most common method for determining the grade analysis of powdered materials.

Composite materials have been synthesized by levigating TiO2 with polyethylene(PE) [4] or nylon(NL) [5] as substrate.
On the basis of these porous materials, attaching nano-sized inorganic particles to the porous materials is expected to generate a novel composite material with unique properties [10-11].

The speed of the mold and materials plummeted to zero.
After the impact, the main vibration table will separate with the molding molds and materials.
After Bill of Materials will also respectively pulse incentive in the B point and D point.

Nano-hardness is an important indicator of the material on nano scale, through measurement and analysis of nano-hardness, people can obtain a variety of other properties of the material indirectly, such as elastic modulus, yield strength, etc.
Meyer index, a constant depends on the material properties, for most of metals is concerned, n generally less than 2.
Hardness of the same experimental sample, if there are the same indentation angle, then the geometry is similar to, and the materials on the same stress state, thus the experimental results reflected the same nature of the materials, so the same hardness value.
