Ceramic airgel is expected to be used as aerospace insulation materials
Recently, the Harbin Institute of Technology, Lanzhou University, University of California Los Angeles, University of California, Berkeley and other universities together researchers synthesized airgel meter hyperbolic structure of the ceramic layer structure, the material can greatly enhance the traditional ceramic airgel the properties of the material, providing research ideas for solving the problem of brittle ceramic ultra-light structure, and thermal crystallization problems and promote the application of ceramic airgel insulation, catalysis, energy, environmental management, aerospace and other fields. because of its lightweight ceramic aerogels, refractory, corrosion, temperature and other characteristics, is very suitable for aerospace use as insulating material, but its brittleness, crystallization temperature, thermal shock problems such as collapse seriously restricted the research and application. The research results obtained graphene airgel basic research based on five years, and took two years to complete. According to project leader, Associate Professor of Harbin Institute of Technology Xu Xiang introduction, basic research projects completed early super-elastic graphene airgel, a negative Poisson\’s ratio, ultra-light, conductive, fluid behavior, energy consumption and behavior research. On this basis, the use of CVD technology team graphene airgel template situ deposition of the ceramic, and by the method of heating the etching template, not only the ceramic airgel having a negative Poisson\’s ratio characteristics, and through the aperture wall \”double-walled\” sub-structure, while achieving a negative thermal expansion properties of the ceramic aerogels, thereby enhancing the mechanical properties of ceramic airgel thermal and the like. Xu Xiang said that the preparation of ceramic airgel CVD is the key to the study. To give ceramic airgel flexibility, control the wall thickness of the wall of the hole, to improve the crystallinity of the ceramic aerogels, and to achieve the structural design, the researchers repeated the experiment after nearly a thousand times. The ceramic aerogels having ultra-light measurement system characteristics such commercial test its thermal conductivity can not, therefore, build a team of specialized measurement equipment, and the reliability of the feasibility studies. The researchers said the study is only the beginning, the research team will continue to develop more flexible, able to adapt to higher operating temperatures, has a lower thermal conductivity of the ceramic ultra-light airgel structure, to further promote multi-ceramic airgel a wide range of applications.

Ceramics Information: is a natural clay ceramic and various natural minerals as main raw material after pulverization kneading, molding and calcining the resulting material, various articles. With the clay before it is made into a high temperature in a special kiln fired ceramic article referred to, pottery and porcelain ceramics in general. It refers to the traditional concept of all ceramic clay as a raw material and other inorganic non-metallic mineral artificial industrial products. It comprises a mixture containing clay or clay by kneading, molding, firing various articles made. From the coarsest to the finest soil is fine pottery and porcelain are all its scope. For its main raw material is taken from the natural silicate minerals (e.g., clays, quartz, etc.), and thus the glass, cement, ceramics, refractories and other industrial, belong to the category \”silicate industry\”. The main producing areas of ceramics Peng town, Jingdezhen, Liling, high security, Harvest, Pingxiang, Lichuan, Foshan, Chaozhou, Dehua, Zibo, Tangshan, north, and other places. In addition Jingdezhen is one of the \”porcelain capital\” in China. the history of TaoHistory of porcelain is an important part of the history of Chinese civilization, China, as one of the four ancient civilizations for the progress and development of human society has made outstanding contributions to the invention and development of ceramic which has a more unique meaning, Chinese history, each has a different artistic styles and different technical characteristics towards generations. English in \”china\” both the Chinese meaning, but also ceramics mean, clearly it demonstrates China is \”the hometown of ceramics.\” In early European porcelain manufacturing technology to master a thousand years ago, Han had produced a very fine ceramics. China is one of the first countries in the world use pottery, porcelain and China because of its high practical and artistic and highly respected world. With the development of modern science and technology over the past century and the emergence of many new varieties of ceramics. They are no longer used or rarely used clay, feldspar, quartz and other traditional ceramic materials, but the use of other special materials, and even extended to non-silicate, non-oxide range, and a lot of new technology. The word literature has been the United States and some European countries \”Ceramic\” understood as a generic term for a variety of non-metallic inorganic solid materials. So in fact the ceramic meaning far beyond the narrow traditional concept of the past. In China, produced pottery art can be traced back 4,500 years to 2,500 years ago in the era before the era can be said that an important part of the history of the development of the Han is the history of the development of ceramics, Han working people\’s achievements in science and technology as well as the pursuit of beauty and shape, in many ways through the ceramic production to reflect and form very typical of each era of technology and art features. Long before European porcelain technology to master a thousand years, China has been able to produce very fine porcelain. From the history of the development of China\’s ceramics, the general is to \”ceramic\” the term into two, to pottery and porcelain two categories. Chinese traditional ceramic development, experienced a fairly long historical period, type of complex, special process, so that the classification of Chinese traditional ceramic technology in addition to considering mandatory targets, but also needs to consider the classification method has always been the traditional habits, combined changes in the ancient and modern scientific and technological knowledge, in order to more effectively categorize draw conclusions.
