| The bottle is immersed in hydrochloric acid then fluoric acid to strip it and make it opaque or translucent, silky or matt. |
|
| This study demonstrates the effect of various machining parameters on mask layer, followed by wet chemical etching in potassium hydroxide and hydro fluoric solution. |
|
| It is found that the encapsulation of TiO2-x species on the surface Pt clusters was induced and modified by thermal reduction and fluoric acid treatment. |
|
| All material applicable for infrared welding like e.g. PP and practically all fluoric material like PVDF, PCTFE, PFA etc. can be processed easily and securely with this machine without any system bonding. |
|
| However, an increasing number of problems were encountered with the transport timing belts coated with the fluoric elastomer Viton®, on which the glass panes to be processed are being transported. |
|
| Under PSR conditions, like in electroslag remelting, slag on basis of fluoric calcium, oxides of calcium, aluminium, magnesium, etc. |
|
| In addition, in case of use of unrefined fluoric calcium as a slag, content of nitrogen in the ESR ingot is even lower than in the VAR ingot. |
|
| In our previous work, is has been clearly known that the damaged layer withstands against aqueous potassium hydroxide solution, while it dissolves in diluted hydro fluoric solution. |
|
| Used in this process fluoric calcium not just failed to ensure removal of impurities from titanium but, vise versa, the available in it impurities transferred into the ingot. |
|
| Remelting of the consumable electrode was performed under the flux represented by a mixture of fluoric calcium, alundum, magnesite, silica, and manganese oxide. |
