Gallium nitride (Ga N) is a binary III/V direct bandgap semiconductor commonly used in light-emitting diodes since the 1990s. The compound is a very hard material that has a Wurtzite crystal structure.Its wide band gap of 3.4 eV affords it special properties for appliions in optoelectronic, high-power and high-frequency devices.

Lead glass - Wikipedia
Properties The addition of lead oxide to glass raises its refractive index and lowers its working temperature and viscosity.The attractive optical properties of lead glass result from the high content of the heavy metal lead. The high atomic nuer of lead also raises the density of the material, since lead has a very high atomic weight of 207.2, versus 40.08 for calcium.

Concretion - Wikipedia
A concretion is a hard, compact mass of matter formed by the precipitation of mineral cement within the spaces between particles, and is found in sedimentary rock or soil. Concretions are often ovoid or spherical in shape, although irregular shapes also occur. The word ''concretion'' is derived from the Latin con meaning ''together'' and
