OBTAINING SINTERED PARTS OF BASALT POWDER
Abstract
Unconventional materials such as composite, ceramic and mineral materials can be used, along with other technical materials, in various fields of technology. The most diverse processes and technologies can be applied to them in order to obtain finished parts, thus reducing the consumption of expensive and deficient materials. Basalt, which belongs to the category of mineral materials, can be processed by melting and recrystallization, sintering or basaltization. As a result of these processes and processing technologies, basalt improves its main mechanical, physical and chemical characteristics, becoming resistant to temperatures between 4000 ... 6000C, mechanical shocks and corrosion. Under these conditions, basalt can also be used advantageously in the construction of the resistance structures of certain engines, especially for combustion chambers and nozzles, along with other materials already used.
