Additives like BaSO4 or SrSO4 can provides seeds for cristalization for PbSO4 crystals. |
![]() |
In the SrSO4 case, due to his close similarity in latice parametes with PbSO4 the PbSO4 crystals will start to crystalize earlier than in the BaSO4 case |
![]() |
PbSO4 crystals formed on the SrSO4 are more difficult to disolve in the reduction phase |
