Abstract
These halogen-containing tin oxide particles have a BET specific surface area of 25-100 m/g and a crystallite diameter of 8-30 nm. The particles optimally contain 0.01-0.75 mass % halogen. Fluorine is optimally contained as the halogen. Optimally, the particles additionally contain tantalum, niobium, phosphorus, antimony, tungsten, or molybdenum. The volume resistivity is optimally 0.1-1000 Ω·cm.
