Basics
- A chemical compound with the chemical formula of CaC2
- Used for production of Acetylene and for Carbon Capture
Production
“Easy” Way
- Used Metallic Calcium and
“Hard” Way
- The more traditional large scale route
- Uses Calcium Oxide and Carbon
- Industrially “Lime” and Coke are used
- These are put into an Electric Arc Furnace
- Then Calcium Carbide is Produced
To-Do’s
- Open Source Electric Arc Furnace
- Open Source Carbon Arc Electrode / Carbon Electrode
- The main DIY/OS method used is the Carbon Electrode from 6v Lantern Battery
- The main downside about this is they are becoming harder to find, and this is a bit wasteful of a sourcing method
- Smaller Electrodes (Even “Pencil Leads” ) are pretty common
- Synthetic Graphite seems to be made from a Carbon Matrix and/or Base such as Carbon Black / Petcoke which is then put in a Kiln and heated until fusion
- Need to look into if pressure is needed too / if so how much
- Carbon-Carbon Composites are a related material
- Another Disadvantage is Even “Proper” Materials like Fire Bricks and Refractory Rement etc still degrade over time, and ESPECIALLY do so under the conditions of an EAF
- Looking into industry solutions may be needed, if they use Sacrificial Walls or Water Jacketed Walls etc
- Emissive Heat Resistant Coatings may be relevant as well
- To an extent, a Carbon Foam “bowl” / Crucible and a SINGLE Graphite Electrode may suffice and be far easier to produce
