Dust particle ordering is discussed in various types of low-temperature pla
sma, such as thermal plasmas at atmospheric pressure, dc glow discharges, U
V- and radioactivity induced plasmas. The investigations of UV- induced dus
ty plasma were made under microgravity conditions. Experimental data are pr
esented. Properties of ordered structures are discussed and the conditions
of formation considered. (C) 1999 American Institute of Physics. [S1070-664
