    Abstract: Multimetal oxide compsn. of formula (I) is new: (A)p(B)q(I): A = Mo12X aX bX cX dSeX fO x; B = X 12CugX hOy; X = P, As, B, Ge and/or Si; X = V, Nb and/or W; X = H, up to 97 mole-% of which may be replaced by K, Rb, Cs and/or NH4; X = Sb and/or Bi; X = Re and/or Rh; X = Mp, W, Nb and/or Ta; X = Li, Na, K, Rb, Cs and/or NH4; a = 1-6; b, d = 0-6; c = 3-5; e, f = 0-3; g = 4-24; h = 0-20; x, y = values depending on the valency and content of elements other than O; p, q = values other than O, with the ratio p/q = 12:0.1 to 12:48. The A and B fractions are each in the form of 3D zones, which differ in chemical compsn. from their local surroundings, and the relative distribution of the A and B zones is as in a mixt. of finely-divided A and finely-divided B.

    Abstract: Coating of solid particles in a fluidised bed by application of a gaseous coating agent from a plasma, wherein the plasma is generated outside the fluidised bed at a pressure of 0.01 to 500 mbar, and the plasma-activated gas is passed into the fluidised bed which is operated at a pressure of 0.1 to 500 mbar, where a. the plasma is generated from the total amount of gaseous coating agent with or without another gas, or b. the plasma is generated from a portion of the gaseous coating agent with or without another gas, and the remaining portion is introducd directly into the fluidised bed, or c. the plasma is generated from another gas, and the total amount of gaseous coating agent is introduced directly into the fluidised bed.

    Abstract: Multimetal oxide compsn. of formula (I) is new: (A)p (B)q (I): A = Mo12VaX bX cX dX eX fX gOx (co-phase); B = X 12CuhHiOy (key phase); X = W, Nb, Ta, Cr and/or Ce; X = Cu, Ni, Co, Fe, Mn and/or Zn; X = Sb and/or Bi; X = Li, Na, K, Rb, Cs and/or H; X = Mg, Ca, Sr and/or Ba; X = Si, Al, Ti and/or Zr; X = Mo, W, V, Nb and/or Ta; a = 1-8; b = 0.2-5; c = 0-23; d, g = 0-50; e = 0-2; f = 0-5; h = 4-30; i = 0-20; x, y = values depending on the valency and content of elements other than O; p, q = values other than O, with the ratio p/q = 160:1 to 1:1. The A and B fractions are each in the form of 30 zones, which differ in chemical compsn. from their local surroundings, and the relative distribution of the A and B zones is as in a mixt. of finely-divided A and finely-divided B. Also claimed are multimetal oxide compsns. of wolframite structural type, of formulae (II), (III), (IV) and (V): in (II), 1/(A+B+C+D+E) = 0.7-1.3; F = 0-1; and B+C+D+E = over 0 to 1. In (III), 1/(A+B+C) = 0.7-1.3; A, B, C all = more than O and B+C = at most 1; In (IV), 1/(A+B) = 0.7-1.3; A, B both = more than O and B = at most 1; In (V), 1/(A+C) = 0.7-1.3; A, C both - more than O and C - at most 1.
