Since the characteristics of lonsdaleite are unknown to most people outside of scientists trained in geology and mineralogy, the names "lonsdaleite" and "hexagonal diamond" have frequently been used in the fraudulent sale of worthless ceramic artifacts, passed off as meteorites on online e-commerce sites and at street fairs and street markets ...
Mineral wool is also known as mineral cotton, mineral fiber, man-made mineral fiber (MMMF), and man-made vitreous fiber (MMVF). Specific mineral wool products are stone wool and slag wool. Europe [who?] also includes glass wool which, together with ceramic fiber, are entirely artificial fibers that can be made into different shapes and are ...
A superhard material is not necessarily "supertough". For example, the fracture toughness of diamond is about 7–10 MPa·m 1/2, [16] [17] which is high compared to other gemstones and ceramic materials, but poor compared to many metals and alloys – common steels and aluminium alloys have the toughness values at least 5 times higher.

Microscopy of an ECM produced from municipal solid waste incinerator ash and carbon fiber waste. SEM image of zeolite crystals on the cell wall of an engineered cellular magmatic. Engineered cellular magmatics (ECMs) are synthetic stone of glass and ceramic.
Diamond-like carbon (DLC) is a class of amorphous carbon material that displays some of the typical properties of diamond. DLC is usually applied as coatings to other materials that could benefit from such properties. [1] DLC exists in seven different forms. [2] All seven contain significant amounts of sp 3 hybridized carbon atoms.

Engineered stone is a composite material made of crushed stone bound together by an adhesive to create a solid surface. The adhesive is most commonly polymer resin, with some newer versions using cement mix. This category includes engineered quartz (SiO 2), polymer concrete and engineered marble stone. [1]
