However, the existing precious metal phase diagrams are far from able to meet the needs of the development of the precious metal materials science and technology.
With the rapid development of the materials science and technology, it is necessary to develop new precious alloys with multifunctional and better performance.
Ternary system: Au-Ag-Y Au-Ag binary alloys are widely applied in contact materials, brazing materials and decorative materials.
Moreover, Au-Pd alloy can be used as solder, hydrogen purifying materials and catalyst materials.

If sepiolite can be exploited and applied scientifically to form industrial scale, its products could not only meet the needs of high-end building materials of thermal insulation and refractory materials, but also they will be widely used in friction materials, carrier materials, absorbent materials and organic or inorganic composite materials.
At the same time this method are time and raw materials consuming and complex [16-17].
During grinding process, air force and materials contact by line, when external stress is greater than internal stress of materials themselves, the materials are split in the direction of long axis, and this method is beneficial to the protection of fibrous and needle-like material structure.

Of the characterizations for these carbon materials, morphology investigation is very important, which would provide with structural characteristics and help to evaluate the materials.
Since invented in 1980’s, SPM has been widely used to investigate the micro-morphology of all kinds of materials such as solid films, life tissues, powder, bulk materials and composite materials, etc[5-7].
The physical and chemical properties of the materials have been studied and corresponding research results have been submitted to other journals for publication.

Introduction Porous materials [1, 2] are the materials contain pores (voids) which are connected or closed.
Porous materials are commonly found in nature and industrial materials such as manufactured metals with an number of pores to reduce weight, save materials, and increase heat retention.
Porous materials are used currently in many areas of applied science and engineering.
Ordnance material science and engineering.
Advanced engineering materials.

Along with the development of science and technology, boron nitride materials are made into coating widely, put it in the surface of metallic materials or non-metallic materials, can extend their service life significantly [1].
Surface engineering technology has became a comprehensive subject involving materials science, tribology, surface physics, chemistry, mechanics, material failure and protection, corrosion and protection, optoelectronics.
It has high reaction melting point, avail for coating of high melting point materials; 2.
The characteristics of the chemical vapor deposition Chemical vapor deposition (CVD) applied most widely in semiconductor industry for depositing a variety of materials , including a wide range of insulation materials, most of the metal material and metal alloy material.
