The Brief Introduction Of Graphite Nozzle

Graphite material has the characteristics of light weight, high temperature resistance and ablation resistance. It is the preferred material for the solid rocket motor (SRM) of small rocket, graphite nozzle. As early as 1947, the United States launched solid rocketsonde successfully using graphite

From Powders to Parts: A Look into the Carbon Graphite

The manufacture of plain carbon graphite is time- and process-intensive. But material processing often does not end there. In addition to the many different types of plain carbon graphite, there are also many different post-bake processes that plain carbon graphite can undergo to further enhance certain material properties for specific applications.

Study of the Carbonization and Graphitization of Coal Tar

Silicon carbide nanoparticles (nSiC) have been used to modify coal tar pitch (CTP) as a carbon binder. The influence of ceramic nanoparticles on the structure and microstructure was studied. The structure of CTP-based carbon residue with various nSiC contents was analyzed by using SEM with EDAX, Raman spectroscopy, and X-ray diffraction. The effect of ceramic nanofiller on the crystallite
