Production
It can be produced by mixing dysprosium(III) chloride or dysprosium(III) carbonate into 40% hydrofluoric acid.[1]
- DyCl3 + 3 HF → DyF3 + 3 HCl
- Dy2(CO3)3 + 6 HF → 2 DyF3 + 3 H2O + 3 CO2
gollark: That... is not how patents work.
gollark: It seems really weird that nobody is making cheaper insulin, considering that patents on it have probably expired by now. Are there difficult regulatory hurdles?
gollark: Possibly. Arguably it doesn't inherently have one but is just assigned one by humans.
gollark: I wouldn't say the virus has a goal any more than a computer program does or something. The difference is that if you set an intelligent thing a goal, it can reason about the best way to accomplish it.
gollark: Also, large-scale competition burns a ton of resources which would ideally not be used up.
