 In 1897, Georges Friedel synthesised and identified calcium chloroaluminate which received his name.Georges Friedel also synthesised calcium aluminate in 1903 in the framework of his work on the macles theory.The presumption that solid and liquid are adjacent states of matter was undercut by Friedrich Reinitzer in 1888 when he noted a cloudy mesophase of cholesteryl benzoate between 145.5 °C and 178.5 °C.
