Non-centrosymmetric borates K7CaR2(B5O10)(3) have been synthesized by solid state reaction and successfully grown by the top seeded solution growth method using K2O-B2O3-CaF2 flux. IR, Raman, absorption spectra as well as data on melting temperature for the crystals were obtained. Optical properties like UV absorption edge and SHG intensity were compared with KH2PO4 (KDP) and K7CaY2(B5O10)(3).
