摘要： A pyroelectric ceramic having the composition:- where ⌀ is U (uranium) or Mn (manganese) and in which a is a number substantially within the range 0.01 to 0.10; x is a number substantially within the range 0.10 to 0.25; y is a number substantially within the range 0 to 0.4; z is a number substantially within the range 0 to 0.05 and 8 is a number substantially within the range 0 to 0.06. Methods of fabricating the pyroelectric ceramic are also described.
