X-ray powder analysis of solid solution of NaH2PO4 and KH2PO4 with H3BO3 was carried out. Both the systems were observed to be tetragonal. The crystallographic data are reported.

A new optical interferometric technique to measure the electrostrictive coefficients of XH2PO4/H3BO3 binaries (where X=Na, K and NH4) is reported. This direct method is found to be advantageous in measuring the positive as well as the negative sign of the electrostrictive coefficients. Design of the apparatus and its merits are discussed. In XH2PO4/H3BO3 binaries the addition of boric acid is found to decrease the value of binary electrostriction coefficient in comparison to their pure samples.

Linear thermal expansion coefficient, dielectric data and transition temperature of KH2PO4-H3BO3 binary are reported. The transition temperature obtained from differential scanning calorimetry (DSC) is in concurrence with the dielectric and thermal expansion data. Further, this transition is classified as first order. Thermal expansion coefficients and enthalpy values of the binary are reported and compared with the data of pure KH2PO4.
