Abstract
Phosphates belong to the extensive group of inorganic pigments that are very often used in industry of plastics and anticorrosive paints. Also, the powders of newberyite MgHPO4·3H2O and α-pyrophosphate Mg2P2O7 can find the usage in this field. Thus, these compounds were the centre of our attention. Newberyite and α-pyrophosphate were synthesized by the method of gelling. Impact of various ways of synthesis, especially reaction conditions, on the structural, thermal, physical and optical properties was investigated. α-pyrophosphate was synthesized by the thermal decomposition of newberyite at temperature around 500°C. Both powders are white color, but the newberyite is the whitest one. The reaction pH particularly affected the particle size distribution and optical properties.
