Preparation and Properties of SiC Porous Ceramics Made by Oxidation-bonding Technique Hongfang Li1, a, Yi Xia2, b and Hongling Zhao2, c 1Dept. of Civil Engineering, Luoyang Institute of Science and Technology, Luoyang, China; 2College of Materials Science and Engineering, Henan University of Technology, Zhengzhou, Henan, China alihongfang1976@163.com, bxylirr@yeah.net, czhaohn2007@163.com Keywords: SiC porous ceramics, Oxidation-bonding technique, Carbon content.
The SiO2 glass phase or mullite is produced during oxidation and they endow the materials high strength.
Experimental Using high pure SiC powder (180 mesh，320 mesh，800 mesh), carbon black powder (C), uf-Al2O3 as main raw materials, carboxymethyl cellulose (CMC) as the binding material.
But the surface of the materials treated at 1450°C is severely oxidized.
There appeared needle-like materials in SiCC30, SiCC40 and SiCC50 after treated at 1350°C, and these needle-like materials gradually decrease with the increase of C content.

Introduction Silicon wafers are most extensively used materials for IC substrates..

The results show that soilbags have a relatively high damping ratio and variable horizontal stiffness so that they can be used as base isolation materials.
Besides, soilbags are cheap and easy to acquire; furthermore the materials inside soilbags may be various construction wastes, such as crushed concrete, asphalt and tile wastes.
If used in the reconstruction of earthquake-affected areas, this technology contributes greatly to the recycling of waste materials.
Fig.5 shows the variation of G withσv andγof soilbags filled with different materials at the maximum shear strain of 1%.

Through optimizing the anchor parameters, the reinforcement ability of anchor bolt and self-bearing capacity of surrounding rock would receive full play, realizing the bolt-rock joint bearing, not only obtaining good reinforcement effect, but also saving the anchor bolt quantity, reducing the consumption of supporting materials and the cost of support[10].
The roof displacement is small due to the roof material is siltstone relatively hard.
