Цитата: Цитата"The NRL developed a method to make spinel, a gemstone that can be mined in a variety of colors, transparent and produce it in sheets. The low-temperature process, called sintering, uses a hot press to mold the material. The technology is scalable, limited only by the size and shape of the press. Using shaped presses, such as a ball-and-socket press, the spinel can be made in to multiple shapes, such as a wing for an unmanned aerial vehicle."
