high pure graphite boat for gold/silver casting

Dear friend please read the following carefully.

 We have our own factory. Comparing to trading companies, we can guarantee the products' quality. Our products' price is also very competitive because we don't have intermediate links.

 Our products include graphite rods, blocks and all kinds of graphite crucibles, molds, etc. We use pitch coke to produce graphite crucible and blocks, with no petrol coke added, ensuring the high density, high purity and high strength of our products. Whereas in order to cut the cost, many Chinese companies mix petrol coke with pitchcoke to produce graphite rods, reducing the graphite products’ strength and their resistance to oxidation, acid,and alkali.  A second differentiator from our competition is that we produce the graphite rods and blocks that  we use to manufacture our products, giving us full control of the quality of our product.

Here are the images for actual pitch coke product(This is our product):

Graphite crucibles made of pitch coke have much higher density. After being polished,the surface of the product is shiny and smooth. Whereas petrol coke graphite crucibles' surface is rough,and  also has many tiny holes.
