Good-quality and fairly large-sized single crystals of PbB4O7 (PbO . 2B(2)O
(3)) were grown by the top-seeded melt-growth method. The transparency rang
e of these crystals was measured to be 240-3600 nm. The transmission fracti
on for an as-grown crystal plate was found to be similar to 80%. Characteri
zation of the grown crystals was carried out using X-ray diffraction, DTA/T
G, and X-ray fluorescence techniques to establish their quality. (C) 2001 E
