Two series of ternary systems were investigated. The first series composed of mixtures (90BCAB + 80BCAB) and 10TPCHB, the second one composed of 80BCAB and mixtures (10TPCHB + 9TPCHB). There was observed the destabilization of the smectic A 1 phase followed by a nematic gap on the one side of the diagram and the extension of the smectic phase and the nematic reentrant phase on the other. The factors affecting the stability of smectic A phase and of the resulting S Ad and N re ones in these mixtures were determined.
