The rate of sulfidation of lead and lead alloyed with small amounts of bismuth, sodium or silver has been studied at 250, 275 and 300 C (482, 527 and 572 F). The rates decrease in the orders Sodium-doped lead, bismuth-doped or undoped lead and silver-doped lead. Only the silver-doped lead sulfidized with parabolic kinetics. The remainder sulfidized with linear kinetics because of the cracking of the sulfide layer on the lead.
