crucibles for melting platinum feature: 1. High temperature: the melting point of graphite crucible is 3850, the boiling point is 4250, even after the ultrigh temperature arc ignition, the loss of weight is small, and the thermal expansion coefficient is intensity of the graphite increased with the temperature, and the graphite strength doubled in 2000
Graphite Crucible Graphite Die for Gold Silver Platinum Melting Casting Lost casting technology of grate bars: The lost casting technology used in the grate bar has excellent high temperature oxidation resistance, high temperature strength, high temperature creep performance and room temperature impact toughness, significantly improving the service life of...
Graphite ore processing methods are generally based on the type of graphite ore and the requirements of graphite products, and then we determine which method to us. The following professional production of graphite ore we shared is three kinds of graphite ore processing methods, just for your reference: The processing of crystalline graphite mineral processing Crystal graphite natural
Hot sale ginegrained graphite block as crucibles for melting metal, US 3 9 / Kilogram, Henan, China, PDSKY, from Pingdingshan Kaiyuan Special Graphite Co., Ltd. on
Consequently, energy efficient crucibles with high graphite content in the carbon binder are often selected to provide high thermal conductivity for faster melting in these furnaces. Crucibles designed for electric resistance furnaces are normally basin shaped and provide a uniform distance between the crucible and the furnace heating elements.

Company Introduction of PDSKY. Established in May 2008, Pingdingshan Kaiyuan Special Graphite Co.,Ltd. located in Weidong District Pingdingshan City, is mainly focus on the production of special graphite and deep Crucibles graphite for melting platinum processing of graphite products, Companys project belongs to the national Torch Project. We have a strong technical team which over
Crucibles are used to melt and process materials at excessive temperatures. They are available in a variety of shapes and sizes, and are composed of materials that can withstand extremely high temperatures, such as alumina, silicon carbide, quartz, or watercooled may be large vessels, builtin place liners for industrial iron or aluminum melting in primary production plants, metal
Clay graphite on the other hand has a melting temperature ranging from 850 degree celsius to 1600 degree celsius. Graphite crucibles are for melting precious metals such as gold, silver, platinum, palladium. The graphite crucible has extremely good thermal shock resistance allowing fast melting
Graphite blocks is the widely used graphite material and be used in many industies, from the material it can be divied into carbon blocks and graphite blocks, the difference is if the blocks is with the procedure of the graphitization . and for the graphite blocks, from the moulding method, it can be divided into three major kinds, isostatic graphite blocks, moulded graphite blocks and

#0183;#32;About 80% of the worlds reserves for platinum group metals (PGMs) are in South Africas Bushveld Igneous Complex. Processing of PGM involves comminution, flotation, smelting, converting, base metals refinery and precious metals refinery. Due to increasing chrome content in the feed and the challenges associated with operating high chrome feed, alternative routes to smelting of PGM are
Work on the melting of the other platinum group metals (pgms) and modern methods for melting the metals are also discussed. Early Attempts to Melt Platinum Before 1782 little more than a partial agglomeration of platinum had been achieved, mainly by hot forging from the powder which, although it sufficed to make many platinum artefacts, did not produce homogeneous molten metal ( 13 ).
Graphite Crucible China Graphite Mold, Graphite Block Graphite crucible can be used for nonferrous metal smelting and casting, dissolving gold or silver ornaments, analysis of special type steel, sintering hard metal. Read More We''re wellknown as one of the leading graphite
