Check Digit Verification of cas no

The CAS Registry Mumber 15572-25-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,5,7 and 2 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 15572-25:
(7*1)+(6*5)+(5*5)+(4*7)+(3*2)+(2*2)+(1*5)=105
105 % 10 = 5
So 15572-25-5 is a valid CAS Registry Number.

Phase equilibria in the Tl2Se-PbSe system and growth and properties of Tl4PbSe3 single crystals

The influence of the ionic component of the electrical conductivity on the semiconductor-metal transition in liquid Tl-Se alloys

Sklyarchuk,Plevachuk

, p. 47 - 51 (2001)

Experimental investigations of electrical conductivity σ(T) and thermo-e.m.f. S(T) were performed for liquid Tl-Se alloys in the region of the stoichiometric compound Tl2Se in a wide temperature range (from 600 K to 1700 K). It was shown that the existence of an ionic component in the electrical conductivity affects significantly the peculiarities of the metallization process of the liquid cells. A model explaining the unusual thermo-e.m.f. behavior, which forms a large deviation from the 'classical' dependence in a wide temperature range resulted from the effect of electron-hole compensation, has been proposed. The ionic contribution essentially changes the electrical conductivity resulting in a deformation of the exponential curve σ(T).

Quasi-ternary system Tl2Se-AgTlSe-TlBiSe2

Babanly,Aliev,Azizov,Babanly

, p. 126 - 128 (2007)

The quasi-ternary system Tl2Se-AgTlSe-TlBiSe (A) has been investigated by DTA, X-ray powder diffraction, microstructural analysis, and microhardness measurements. Polythermal sections AgTlSe-TlBiSe2, AgTlSe-Tl9BiSe6, [Ag0.5Tl1.5Se]- TlBiSe2, Tl2Se-AgBiSe2 (0-50 mol % AgBiSe 2), an isothermal section at 500 K, and the projection of the liquidus surface of system A have been constructed. It has been shown that the quasi-binary join AgTlSe-Tl9BiSe6 divides system A into two subordinate triangles, namely, Tl2Se-Tl9BiSe 6-AgTlSe (B) and AgTlSe-Tl9BiSe6-TlBiSe 2 (C). The phase diagram of subsystem B involves a univariant eutectic equilibrium while subsystem C involves an invariant eutectic equilibrium. The ternary eutectic has the coordinates 650 K, 10 mol % TlBiSe2, and 61 mol % AgTlSe. A continuous series of solid solutions (0-12 mol % AgTlSe) has been found along the Tl2Se-Tl 9BiSe6 bordering system. The homogeneity region of TlBiSe2 extends to 5 mol %. Nauka/Interperiodica 2007.

Experimental investigation of the 3Tl2Se + Sb2Te 3 ? 3Tl2Te + Sb2Se3 phase diagram

Jafarov, Yasin I.,Babanly, Mahammad B.,Shevelkov, Andrei V.,Aliev, Ziya S.

, p. 184 - 192 (2013/04/10)

Phase equilibriums were established in the 3Tl2Se + Sb 2Te3 ? 3Tl2Te + Sb2Se 3 mutual system mainly by the X-ray powder diffraction and differential thermal analyses, with the aid of microhardness and EMF measurements applied to equilibrated alloys. According to the obtained experimental results the phase diagrams in form of the polythermal section and isothermal section at 300 K as well as the projection of the liquids surface have been constructed. It was found experimentally that the system is mutually reversible and is characterized by a wide solid solubility fields along the TlSbSe2-TlSbTe2 subsystem and within the Tl 2Se-Tl9SbSe6-Tl9SbTe 6-Tl2Te subsystem. The homogeneity and primary crystallization fields as well as the types and coordinates of non- and monovariant equilibriums were determined. The dependencies of crystallographic parameters, microhardness and EMF values upon the composition are discussed. From the EMF measurements, the partial molar functions of thallium (ΔG?,ΔH?,ΔS?) were calculated for the revealed nonstoichiometric quaternary phases.
