What Is a Melting Crucible? (with picture)
2020/8/1· Ray Hawk Last Modified Date: August 01, 2020 A melting crucible is usually a pot-shaped container placed in the center of a furnace that is used to hold a metal to be melted. It is commonly made of silicon carbide and graphite, but can also be composed of metals suited to high temperature appliions, such as tantalum or tungsten.

Overview of Silicon Carbide - Glenn K. Lockwood
Silicon carbide is used as a semiconductor replacement for silicon in many high-powered appliions because of its high temperature capabilities, high frequency abilities, and good switching speed. However, SiC also has found use in ballistic armoring in the form of fiber reinforcers or wet/dry-milled silicon carbide coined with aluminum nitride.

Materials science - High-temperature materials | Britannica
High-temperature materials In order to extract useful work from a fuel, it must first be burned so as to bring some fluid (usually steam) to high temperatures.Thermodynamics indies that the higher the temperature, the greater the efficiency of the conversion of heat to work; therefore, the development of materials for coustion chaers, pistons, valves, rotors, and turbine blades that can
The main difference between these coatings is their maximum service temperature limitation. Tungsten carbide has a max temperature rating of 730 F (400C) and chromium carbide 1300F ( 725C). Chromium carbide is indied where significant corrosion is expected or where high process temperatures are required.
