Abstract The phase diagrams are determined of binary mixtures composed of 4‐n‐alkylbiphenylates 4‐cyanobiphenyl ( n ‐CBB)‐smectics A 1 , for n < 8 and esters of 4‐(trans‐4′‐n‐alkylcyclohexyl)benzoic acid (10CPCHB, 10NPCHB, 10FOPCHB)‐smectics A d. The effect is studied of the smectic layer spacing ratio and polarity of the components on the induction of the nematic phase in the tested series of compounds. The virtual NS Ad phase transition points in series n‐CBB are estimated and the effect is discussed of the stability of the smectic phase and polarity of the molecules of the mixture components on the width and position of the nematic gap.
