The right part of the area was occupied by Cu[Al] solid solution.
TiC laminae were located between Ag and Cu[Al] solid solution.
During the brazing process, due to the intense affinity from Cu, Al and Ti diffused out from Ti2AlC and dissolved into the Cu.
Some of the Ti2AlC were not totally decomposed to TiC and Al, they were transformed into Ti3AlC2 due to partial loss of Al and Ti.

Experimental procedure
To produce Al and W nanopowders we used aluminum and tungsten wires with 99.5% Al and 99.95% W content respectively.
The Al nanopowder was passivated in air, keeping the metal Al content not less than 91 mass percent.

Suresh et al. [17] studied the heat transfer characteristics of Al2O3-Cu/water nanofluid.
As discussed by Qu et al. [19], the nanoparticles suspended at base fluid can enhance and stabilize the nucleation at the evaporator and increase the bubble release frequency, decreasing the thermal resistance of evaporator.

The well known systems are Ti-Al-C, Ti-Si-C and Ti-Al-N.
Traditionally Ti3AlC2-based composites are synthesized from mixtures of Ti/Al/C, Ti/Al/TiC, Ti/Al4C3/C, Ti/Al4C3/TiC, Ti2AlC/TiC and Al/TiCx powders [2-5, 8, 11].

Keywords: potassium aluminium silicate, K-feldspar, ionic conductivity
Abstract: In this study, KAlSi3O8 was synthesized by a solid-phase reaction at 900, 1000 and 1100 °C, using K2CO3, Al2O3 and SiO2 as the starting materials.
Jones et al. have studied the ionic conduction of natural K-feldspar and reported an activation energy of 1.33 eV for ion conduction.

The researchers experimented with different calcination steps, Davidovits et al [13] calcined the clay at 500,650,700 and 750 °C, Palomo et al [14] explored a temperature range of 600-700 °C, Zhang and Sun- Wei [15] at 700 °C, whereas Zibouche et al [8] preferred to treat it at 800 °C.
The paste samples were prepared with NaOH solution 8M in quantity allowing to have a ratio Na/Al close to 1(1:1).
