A process for manufacturing an article includes the steps of applying a quantity of a refractory metal sufficient to produce a coating on a carbon based felt; processing thermally a refractory metal coated carbon based felt at a temperature and for a period of time sufficient to form a ceramic based felt; and cooling the ceramic based felt under a controlled atmosphere.
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.
Tungsten Carbide: This is, in fact, *technically* NOT a metal. (…What!?) It is a compound of Tungsten and Carbon (C), hence the chemical formula WC. Tungsten Carbide is actually very rarely used in plane ceramic form, if ever. Tungsten Carbide is also used in compounds of two parts tungsten, aka W2C. This however is actually tungsten
Silicon carbide, with single-edge precracked beam (SEPB) toughness greater than 7 MPa·m1/2, was made by hot-pressing using Al–B–C (ABC) or Al–Y2O3 (YAG) as additives.

When brazing tungsten carbide bits to steel to create a mining tool, silver braze alloys are often not the braze alloy of choice. Rather, filler alloys are chosen that melt at higher temperatures than silver alloys. Below are three recommended alloys for brazing mining tools.

tungsten carbide, so it offers superb wear resistance and total imper-meability at extreme temperature and pressure, and allows higher velocity and improved heat transfer. In fact, every Hexoloy heat exchanger tube is proof tested to 186 bar (2,700 psi) to assure reliability and added safety. Hexoloy SiC’s extreme hardness also means no
Silicon carbide has been the most widely used material for the use of structural ceramics. Characteristics such as relatively low thermal expansion, high force-to-weight radius, high thermal conductivity, hardness, resistance to abrasion and corrosion, and most importantly, the maintenance of elastic resistance at temperatures up to 1650 ° C, have led to a wide range of uses.
Examples include calcium carbide (CaC2), silicon carbide (SiC), tungsten carbide (WC) (often called simply carbide when referring to machine tooling), and cementite (Fe3C), each used in key industrial appliions. The naming of ionic carbides is not systematic.

24.08.2020· As tungsten carbide, it has double the stiffness and density of steel. The carbide is extremely hard, and resistant to high temperatures. This makes it an ideal material for cutting tools like high speed drill bits. They’re better at maintaining a sharp cutting edge, they enable faster machining, and in general the result in a better finish.
