· TaS2

Tantalum disulfide (TaS2) is a layered transition metal dichalcogenide ceramic compound that belongs to the family of two-dimensional materials with weak van der Waals bonding between atomic layers. While primarily a research material rather than an established commercial ceramic, TaS2 is investigated for applications requiring low-dimensional electronic properties, including thin-film electronics, energy storage devices, and catalytic applications. Its layered structure makes it particularly notable for exfoliation into ultrathin nanosheets, positioning it as a promising candidate for next-generation nanoelectronic and electrochemical devices where conventional bulk ceramics are impractical.
