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: External GPU docks?
gollark: There's some mechanism for trusting specific devices, except apparently it's based on some UUID thing which can just be copied into a different device, and there have been at least two exploits in the security it has.
gollark: Now, they did think of this!
gollark: It allows PCIe to external devices, and PCIe allows direct memory access, obviously a giant security risk.
gollark: Thunderbolt is kind of terrible security-wise.
