Аннотация:
The description of an apparatus for preparing precursors of high-T<sub>c</sub> superconductors by spray drying is given. The device is built from ready available laboratory glassware and electrical appliances. It allows the production of precursor materials to a high degree of homogeneity, giving rise to superconducting characteristics for YBa<sub>2</sub>Cu<sub>3</sub>O<sub>7- delta </sub> comparable to those found in samples obtained by other more elaborate preparation procedures.
