K3Ti8O17, a new alkali titanate bronze

Synthesis and characterisation of nanotubular titanates and titania

“…3a), which is well consistent with the previous studies on the hydrothermal synthesis of sodium titanates. [16][17][18][19] According to Watts, 16 titania sheets are composed of [TiO 6 ] octahedra sharing edges with each other, and form a zigzag ribbon structure. With increasing hydrothermal treatment duration, the nanosheets grow, together with the increasing tendency of curling, leading to the formation of short nanotubes (Fig.…”

Crystalline Structure, Synthesis, Properties and Applications of Potassium Hexatitanate: A Review

“…The potassium titanates family comprises a series of compounds of general formula K 2 OnTiO 2 , with n equal to 1, 2, 4, 6 or 8, commonly called potassium -titanate, -dititanate, -tetratitanate, -hexatitanate and -octatitanate, respectively [2][3][4]6]. Moreover, the compounds KTiO 2 (OH) [7,8], K 3 Ti 8 O 17 [9] and The potassium titanates family comprises a series of compounds of general formula K2OnTiO2, with n equal to 1, 2, 4, 6 or 8, commonly called potassium -titanate, -dititanate,tetratitanate, -hexatitanate and -octatitanate, respectively [2][3][4]6]. Moreover, the compounds KTiO2 (OH) [7,8], K3Ti8O17 [9] and K4Ti3O8 and KxTi8O16 [7,[10][11][12] have also been reported but not extensively investigated.…”

All of them have been recognized as important functional materials for a wide range of applications, due to their excellent chemical, thermal, optical, mechanical, catalytic, photocatalytic and frictional properties [13][14][15][16].…”

New reduced ternary titanates from borate fluxes

“…Some species are superconductors, such as SrTiO 3-x (1,2) and the spinel Li 1+x Ti 2-x O 4 for x < 0.16 (3,4). Often, complex ternary titanates adopt structures based on sheared chains of TiO 6 octahedra as in Na 2 Ti 6 O 13 (5), Na 2 Ti 7 O 15 (6), and K 3 Ti 8 O 17 (7). Other representatives of this class have tunnel structures, e.g., related to the hollandite structure as in A x Ti 8 O 16 (A = K, Rb, Cs) (8), or the calcium ferrite structure as in NaTi 2 O 4 (9).…”
