    摘要: A method of using an absorber of electromagnetic radiation, includes absorbing electromagnetic radiation with the absorber finely distributed or dissolved in a carrier material. The absorber is a crystal water-free iron(II) orthophosphate of the general formula Fe3(PO4)2 or crystal water-free iron(II) metal orthophosphate, iron(II) metal phosphonate, iron(II) metal pyrophosphate or iron(II) metal metaphosphate of the general formula FeaMetb(POc)d, where a is a number from 1 to 5, b is a number from >0 to 5, c is a number from 2.5 to 5, d is a number from 0.5 to 3 and Met represents one or more metals selected from the group consisting of Li, Na, K, Rb, Cs, Mg, Ca, Sr, Ba, the transition metals (d block), the metals and semimetals of the third, fourth and fifth main groups, and the lanthanoids or combinations of the above mentioned phosphates as absorbers of electromagnetic radiation.

    摘要: Improved spherical beads that may be used in producing pharmaceutically active pellets by depositing a pharmaceutically active agent on the surface of said spherical beads. The spherical beads includes a pharmaceutically acceptable carrier material, including: a) at least 60 wt. % of phosphoric acid calcium salt and b) up to 40 wt. % of organic material. Greater than or equal to 90 wt % of the spherical beads have a particle size in the range of from 90 μm to 1200 μm. The spherical beads have: a bulk density of at least or more than 1000 g/l, a specific surface area of at most or less than 10 m2/g, and a hardness of at least or more than 600 g/mm2. Also included is a method for producing such spherical beads and to pharmaceutically active pellets being prepared by depositing a pharmaceutically active agent on the surface of the spherical beads.

    摘要: A method of thawing, heating, cooking and/or baking a foodstuff material, in particular a dough-based product, a pasta, a frozen dough, a panada, a minced meat pasta or a vegetable pasta, in a microwave field. The foodstuff material contains an added microwave absorber in an amount of 0.5 to 5.0% by weight with respect to the total weight of the foodstuff material. The microwave absorber is selected from orthophosphates (PO4)3−, hydrogen phosphates (HPO4)2−, dihydrogen phosphates (H2PO4)−, diphosphates (P2O7)4− (pyrophosphates), metaphosphates [(PO3)22−]n, tripolyphosphates (P3O10)5− or more highly condensed phosphates with an average chain length of 3 to 50, carbonates, hydroxides, citrates and gluconates of the metals calcium (Ca), magnesium (Mg), iron (Fe), zinc (Zn) and copper (Cu) with the proviso that the water solubility of the microwave absorber at 20° C. is less than or equal to 50 g/L water and the microwave absorber has a pore volume of more than 3.0×10−3 cm3/g and less than 200×10−3 cm3/g.
