But very limited information is available for hexagonal materials [1,2,3] as compared to cubic materials [4,5,6,7].
For both materials, basal and close to basal orientations have the highest hardness.

Introduction Cement concrete is the most widely used man-made building materials nowadays, which holds an extremely important position in modern architecture and play a role and function that cannot be replaced by other materials in civil engineering fields.
Sustainable development of construction materials A.
Construction materials and the sustainable development.
Developing and introducing green building materials technology, and researching and developing green building material products are the correct way to the sound development of building material industry.

However, in a number of materials (chemically pure Sn, technical Sn, and eutectic alloy) AE signals have been registered below an inflection point on a time-temperature curve, i.e. in a solid condition.
Materials with various concentrations of components crystallize on different mechanisms.
The research activities have been funded by Changchun Science and Technology (No. 13GH15).
Time-frequency analysis of impact sound of composite materials.

High-purity alumina has excellent performance and wide application in high-tech industries and areas of modern materials, so industrialized, low-cost, non-polluting and sustainable development preparation process has become one of the priorities of present high-purity alumina powder research.
The demand and application in high-precision and wear-resistant materials such as the catalyst carrier, the carrier coating, components material of mechanical products, fluorescent translucent coatings and other emerging fluorescent decorative materials, luminescent diode substrate materials, HPS transparent alumina tube, anti-scratch disk of scanner, special optical instrument windows, metal-ceramic additives in lubricating oil, as well as artificial crystals (artificial sapphire and ruby of laser materials) are more and more concerned [2] - [9].

Effects of compositions on the chloride ion permeability of geopolymer concrete Qing Wang1,2 a, Jing Da2,b , Cunbao Zhang2,c, Zhaoyang Ding2,d, Zhitong Sui1,e 1 School of Materials & Metallurgy, Northeastern University , Shenyang, 110004, China 2 School of Materials Science and Engineering, Shenyang Jianzhu University, Shenyang, 110168,China.
Slag and metakaolin were chosen as raw materials and sodium silicate of low module as alkali activator to prepare geopolymer concrete.
Experiment Raw materials.
This can be explained by that the main materials of geopolymer are slag and metakaolin which consist with SiO2 and Al2O3.
