Quartz Graphite Crucible, Small High Purity Cylindrical Graphite Crucible | WH Graphite

Graphite crucible for melting gold/silver/aluminium/copper/metal uses graphite as the main raw material and plastic refractory clay or carbon as binder processing. This kind of graphite crucible for melting copper is mainly used for gold, silver, copper, aluminum, brass and other non-ferrous metal and alloy smelting. Graphite crucible's wall is smooth and the melting loss of precious metals is small.

Extruded graphite block, mainly used for molten iron with casting molds and graphite crucible furnace, powder metallurgy, sintering boat and tray, melting and alloying crucible, etc.

Graphite is an allotroph of carbon, gray black, opaque solid, melting point of 3652℃, boiling point of 4827℃. Solid carbon graphite block, a stable chemical property, is corrosion resistance, and is hard to react with acid, alkali and other agents. Carbon graphite block burns in oxygen at 687℃ to form carbon dioxide. It can be oxidized by strong oxidants such as concentrated nitric acid and potassium permanganate. The graphite carbon block also can be used as an antiwear agent or lubricant. High purity graphite as a neutron decelerating agent in the atomic reactor, can be used to manufacture graphite crucible, electrode, brush, dry cell, graphite fiber, heat exchanger, cooler, arc furnace, arc lamp, pencil core, and so on.

Graphite blocks for sale / graphite block for sale are generally divided into natural graphite blocks and artificial graphite blocks. The most widely used ones are artificial graphite blocks. As one of the biggest graphite blocks suppliers/manufacturers in China, WH Graphite can provide you with all kinds of OEM graphite blocks as you need.

Graphite jewelry molds make original designs of graphite crucibles attached to them for a long time, which keeps high-temperature resistance. Making graphite molds for jewelry is the procedure used to insure that jewelry items can be accurately duplicated at any time future. The mold making process begins with the creation of a metal model. Models can be as simple as a basic ring or complex as jewelry containing multiple interlinking parts used to create elaborate multicolor jewelry.
