Introduction At present, tungsten metal material production is the main method used in powder metallurgy tungsten powder or alloy powder compaction, sintering.
Differential thermal analysis method is at the same temperature to be measured in the system and the reference material to a certain speed heating or cooling, curve recording system tested and does not change the temperature difference between the base material and time.
When the tested system with phase change, because there are endothermic or exothermic reaction, then measured reference material system and reference temperature difference will change, so as to obtain the differential thermal curve reaction endothermic or exothermic Gu Huofeng, according to the curve to determine the phase transition temperature.

Mechanism of Self-Propagating High-Temperature Synthesis of MoSi2 Jianying Gaoa, Lianjun Wangb and Wan Jiangc State Key Laboratory for Modification of Chemical Fibers and Polymer Materials, Donghua University, 2999 People of North Road, Shanghai 201620, China ajianying.g@gmail.com, bwanglj@dhu.edu.cn, cwanjiang@dhu.edu.cn Keywords: Activation Energy, Interface, Morphology, Quenching, Reaction Mechanism.
Microstructural observation on the materials from quenched zone shows MoSi2 particles precipitate from liquid phase.
Using Mo filament (approximately 30 mm in diameter and 1.0-1.5 mm in length) and silicon powder (99.5%, -325 mesh) as starting materials, a pellet was prepared under 30 MPa pressure for synthesizing MoSi2.
Compared to diffusion couple, powder used as starting material in SHS reaction possesses high defect concentration [13].

Oleic acid, which is one of the major fatty acids in palm oil, has been used as a starting material for the synthesis of surfactants.
The use of palm oil fatty acids as a renewable source of raw materials for surfactants synthesis is gaining importance in view of the rise of price of petroleum resources and the green revolution.

It is very important to reconstruct the damaged roads as soon as possible in order to send the external aids and relief aid materials to earthquake-hit areas and transport the disaster victims to hospital in a short time after earthquake.
Many people put up the tents on the sidewalk and road shoulder, many goods and materials were piled up along the roadside.
