Seasoning a graphite crucible? - Bloomers and Buttons - …
31/10/2015· Are you talking about silicon carbide pots ? I''ve never heard of silicon graphite crucibles. I agree that silicon carbide crucibles will outlast clay graphites for non-ferrous metal but they tend to be more expensive and,in my experience, don''t handle steel melts as well as good quality clay graphite pots ( they can also add about 0.5% + Carbon to a charge ).

Crucible and Tongs – TheSupercoreNetwork
For most hobbyists there are two main types of crucibles to pick from these are clay graphite crucibles and silicon carbide crucibles. Both crucibles a have their advantages and disadvantages. you are always advised to check with your supplier if your crucible can survive the temperature and conditions for cast iron as incorrect use may lead to a potentially hazardous situation.
How to make a clay graphite crucible - Know About Life
For a basic crucible, you will require 30 to 50 per cent (by weight) of flake graphite and 10 to 50 per cent silicon carbide. Make sure you include high fire clay in your recipe so that your crucible can withstand the heat of the furnace.

Silicon carbide is a highly desirable material for high-power electronic devices — more desirable even than silicon. And now the problem of producing large, pure wafers of the
how do you make silicon wafers into computer chips
The silicon doesn’t care which way it is spun. So, spinning in a crucible bi-directionally speeds the ingot creation with less burden to the system. Once cooled the silicon crystal seed is pulled from the crucible at a very slow rate of about 90mm per hour.
SiC Powder Silicon Carbide Properties And Appliion …
Silicon carbide (SiC) is fabried from quartz sand, petroleum coke, wooden chips, and different raw materials by excessive-temperature smelting in a resistance furnace. Silicon carbide is likewise determined in nature, but it''s far fairly rare. the main thing of a mineral called Moissanite is silicon carbide. among current non-oxide, excessive-tech refractory substances together with C, N, B
