Titanium carbide, Ti C, is an extremely hard (Mohs 9–9.5) refractory ceramic material, similar to tungsten carbide. It has the appearance of black powder with the sodium chloride (face-centered cubic) crystal structure. It occurs in nature as a form of the very rare mineral khamrabaevite (Russian: Хамрабаевит) - (Ti,V,Fe)C.
Titanium nitride (TiN; sometimes known as tinite) is an extremely hard ceramic material, often used as a physical vapor deposition (PVD) coating on titanium alloys, steel, carbide, and aluminium components to improve the substrate's surface properties.
Boron carbide, B 4 C, on the other hand, has an unusual structure which includes icosahedral boron units linked by carbon atoms. In this respect boron carbide is similar to the boron rich borides. Both silicon carbide (also known as carborundum) and boron carbide are very hard materials and refractory. Both materials are important industrially.
TiN has a hardness equivalent to sapphire and carborundum (9.0 on the Mohs scale), [14] and is often used to coat cutting tools, such as drill bits. [15] It is also used as a gold-colored decorative finish and as a barrier layer in semiconductor fabrication. [16] Titanium carbide (TiC), which is also very hard, is found in cutting tools and ...
Tin(IV) chloride, also known as tin tetrachloride or stannic chloride, is an inorganic compound of tin and chlorine with the formula SnCl 4. It is a colorless hygroscopic liquid , which fumes on contact with air.
IV-VI: 2: Lead telluride: PbTe: 0.32 [5] Low thermal conductivity, good thermoelectric material at elevated temperature for thermoelectric generators. IV-VI: 2: Tin(II) sulfide: SnS: 1.3/1.0 [23] direct/indirect: Tin sulfide (SnS) is a semiconductor with direct optical band gap of 1.3 eV and absorption coefficient above 10 4 cm −1 for photon ...

On average, tin makes up 1 part per million of soil. Tin exists in seawater at concentrations of 4 parts per trillion. Tin makes up 428 parts per billion of the human body. Tin(IV) oxide occurs at concentrations of 0.1 to 300 parts per million in soils. [18] Tin also occurs in concentrations of one part per thousand in igneous rocks. [19]
