Neutral refractory ore deposit classification and distribution of China's domestic reserves of mineral resources neutral refractories, refractory agents are also widely distributed, but less worthy of exploitation. According genesis neutral refractories, refractory generally neutral neutral refractory ore deposit into schist type deposits (Chuzhou neutral refractory ore), porphyry alteration type neutral refractory deposits (Jingdezhen Willow Bay porcelain quarry), alteration of volcanic deposits in Neutral Refractories (southern Zhejiang, Fujian Nanan neutral refractories quartz rock, etc.), secondary quartzite neutral refractories illite deposits (eastern Zhejiang pyroclastic alteration neutral refractory ore type illite), clay, rock type neutral refractories illite deposits (Beijing Huairou, Southern illite clay minerals, etc.), in which the refractory ore schist Neutral exploitation maximum value, because the class feature neutral refractories refractory ore is most obvious. Currently refractory species, the aluminum alloy in one of the main constraints on a large number of automotive applications is its high price than steel, aluminum alloy in order to facilitate the large number of applications in the automotive refractory brand, must reduce material costs. In addition to the development of low-cost aluminum and advanced aluminum forming process, the recycling technology can further reduce the cost of production of aluminum alloy. Another research direction to expand the application of aluminum is to develop a new variety of connectivity technologies, multi-material structure of the car's future development requires the connection of two different types of materials (such as cast-aluminum, steel-aluminum, aluminum-magnesium, etc.), These connections technology and surface treatment technology for anti-corrosion materials and components, the future expansion of aluminum in automotive applications an important issue.
