Silicon Carbide Graphite Crucible for Melting Aluminium, Copper, Zn, Sn Sic Graphite Crucible (JP02)

Graphite crucible have four different main type

Item 1 Pure graphite crucible. The carbon content always > 99%. Machine by pure artificial graphite material

Item 2 Clay graphite crucible. Main raw material always are clay, natural graphite powder, then making the size by Rotational Molding machine. Then baking that. Got the clay graphite crucible

Item 3 Sic graphite crucible rotational Molding type. Main raw material is sic, natural graphite, Al2O3. etc then making the size by Rotational Molding machine. Carbon content from 20% to 50%, sic content 20%-40%. With the Prevent oxidation coating. Density always 1.7-1.85

Item 4 Sic graphite crucible isostatic pressing type, Main raw material is sic, natural graphite, Al2O3. etc carbon content ABOUT 30%, sic content ABOUT 40%. Then making the size by isostaticpressingmachine. Awalys be Europe or Japan brand such as Morgan, MARS ISOMELT, wetro, Foseco, Vesuvius. etc. With high quality. Same sic graphite crucible. The best quality crucible made by this way. Density always 1.95-2.2

Item 1 is different to 234. There are no same place. They are different crucible, different using

If FOR metling copper, gold, silver, zinc, aluminium, lead, cast iron. etc Always using 2.3.4 crucible

Between 2.3...4 With the standard of using life of India morgan crucible (about melting copper more than 200-250 times )

Item 2 Clay graphite crucible The cheapest and the lowest qualiy. The life is always 1/20 to 1/15 of India morgan crucible

Item 3 Sic graphite crucible otational Molding type Middle quality, middle price. The life is always 1/5 to 1/3 of India morgan crucible

Item 4 Sic graphite crucible isostatic pressing type The most expensive, the best quality! A little better than India morgan crucible
