Hollow Glass Microspheres. developed in recent years, are a new type of materials which shows a greater use and an outstanding performance. The product, made mainly from borosilicate, is a hollow microspheres whose grain size is 10-250 micron and wall-thickness 1-2 micron.

Gunpowder

Gunpowder, also known as the retronym black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive.It consists of a mixture of sulfur (S), carbon (C), and potassium nitrate (saltpeter, KNO 3).The sulfur and charcoal act as fuels while the saltpeter is an oxidizer.

Electronic Supporting Information

The thickness of graphite can be estimated by the Scherrer formula, which is expressed as follows (Equation (s1)): L a m q (s1) where L is the grain size (nm), k is the Scherrer constant, 𝜆 is the X-ray wavelength (nm), 𝜃 is the half diffraction angle (degree), and 𝛽

The sintering temperature had bigger influence on the grain size, density and Vickers-hardness of the NPCD, while the sintering pressure had the less impact. The NPCD synthesized at 1 200 ℃/5.5 GPa/15 min is better in the average diamond grain size, density and Vickers hardness, reaching 10.7 nm, 2.70 g/cm3 and 32 GPa, respectively.
