characteristics of graphite crucibles

Experience of Graphite Crucibles during the

Of these, graphite is the most prevalent material due to its ease of fabrication, expense, compatibility with induction systems, and robust characteristics. Graphite in contact with molten uranium will react to form uranium carbide species, thus a coating or mold is needed to prevent reaction of the uranium and the subsequent adherence of the solidified metal.

Matching Your Crucible to Your Application

Selecting such crucibles is often more advantageous because they offer performance characteristics important to your operations. For example, using a crucible able to melt metals from iron to zinc may not be as important to your aluminum alloy melting operation as having a crucible limited to the temperature range you need but able to resist corrosion damage from your metal treatment fluxes.

Silicon Carbide Crucible, Silicon Carbide Graphite Crucible

Silicon carbide crucibles are generally made of carbon bonded silicon and graphite materials. Silicon carbide crucibles are suitable for smelting and melting precious metals, base metals and other metals in an induction furnace. They are used at a temperature

Properties of graphite

A study of the thermal conductivity and the electrical resistivity of the specimens of the graphite-containing TGN, TGG, and TKG type crucibles shows that the characteristics of these properties significantly differ depending on the type of the crucibles and the zones in different parts of a given crucible. It is expected that the properties of a given type of crucibles can vary from product

Influence of casting procedure on silver

In this study the tensile characteristics of endodontic posts cast in silver-palladium alloy using either a graphite or a ceramic crucible were determined. Graphite crucibles were associated with a significantly lower (2P less than 0.00001) percentage elongation than were ceramic crucibles.
