Electric discharge machining has a potential to erode any conductive material (resistivity should not exceed 100 Ω-cm) irrespective of its strength, hardness and toughness [2].
Though complex thermo-electrical phenomena, material inhomogeneity, transient behavior of dielectric fluid result critical surface integrity of the machined part still, mechanism of material removal is preserved in surface topography.
Standard high speed steel cutting tool (measured density 8006 kg/m3) specimen of M2 grade (C-0.80%, W-6%, Mo-5%, Cr-4%, V-2%) is taken as workpiece material and electrolytic copper rod (density 8904 kg/m3) of diameter 12 mm is considered as tool electrode.

Moreover the crystals of above two stoichiometric materials has been considerable interest of been as eximious precursors of cubic-ZrW2O8 and cubic-ZrMo2O8 which are excellent isotropic negative thermal expansion (NTE) compounds over a very wide temperature range [3,4].
Experiment Starting materials were Na2WO4·2H2O (A.R.), ZrOCl2·8H2O (A.R.) in which the hydration water was determined by gravimetric method.

Na2SO4 (m) ⇔ Na2SO4 (g) (1) 2.3 Evaporation of chloride species In commercially produced soda-lime-silicate glass melts, such as container glass melts and float glass melts, chlorides are present due to contaminations or impurities of the applied raw materials or recycled glass cullet.
The coarse cullet (5 - 10 mm) used for these evaporation tests has first been prepared from pure raw materials that are melted above the fining temperature.

There are material specifications typically impose limits on pearlite content in ferritic ductile irons to avoid the alloy dilation and growth associated with decomposition of the pearlite cementite at high operation temperatures [2].
The metallic charge used to prepare the base molten iron consisted of high purity (Sorel) pig iron, steel scrap, ferrosilicon 75%, Ferro-molybdenum 60% as well as carburizing material.
