Thermochromic material comprises 2-98 wt.% of a thermochromic component (I) and 2-98 wt.% of a binder, where (I) is a crystalline material based on bismuth oxide and/or oxides of niobium, tantalum, molybdenum, tungsten or chromium. Thermochromic material comprises 2-98 wt.% of a thermochromic component (I) and 2-98 wt.% of a binder, where (I) is a crystalline material of formula (Ia)-(Ie): (Bi 2O 3) 1 - z(M xO y) z(Ia) (M xO y) m(Bi 2O 3) nM1 2O 5(Ib) (M xO y) m(Bi 2O 3) nM2O 3(Ic) (M xO y) m(M3 xO y) nM4O 3(Id) (M xO y) m(M5 xO y) nM1 2O 5(Ie) z : 0-0.5; M : a heavy metal, alkali metal and/or alkaline earth metal; m : 0-1; n : 1-2 in (Ib), 0-12 in (Ic) or 0-1 in (Id) and (Ie); M1 : Nb or Ta; M2 : Mo or W; M3 : a heavy metal; M4 : Mo, W or Cr; M5 : Cu(II), Mn(II), Mn(III), Co(II), Ni(II) or Cr(III); and x, y : not defined. |
