The coordinates defining a " eutectic point " on a phase diagram are the " eutectic percentage ratio " ( on the axis of the diagram ).
12.
All these line-casting machines used various alloys near the eutectic point and which typically consisted of approximately 4 % tin and 12 % antimony and the balance being lead.
13.
An additional concern was that the hydrogenation product has an unfavorable eutectic point, so it was impossible to isolate the crude intermediate in more than 94 percent ee by batch process.
14.
Not all binary alloys have eutectic points because the valence electrons of the component species are not always compatible, in any mixing ratio, to form a new type of joint crystal lattice.
15.
Amorphous materials do not have a eutectic point, but they do have a critical point, below which the product must be maintained to prevent melt-back or collapse during primary and secondary drying.
16.
Since the compositions of most cast irons are around the eutectic point ( lowest liquid point ) of the iron carbon system, the melting temperatures usually range from, which is about lower than the melting point of pure iron.
17.
For instance, for tin-lead alloy, you only need the melting point of pure tin, the melting point of pure lead, the eutectic point ( temperature and tin / lead ratio ), and the corner points, you can draw your own.
18.
There are four constant-crystallization eutectic points for hydrochloric acid, between the crystal form of HCl�H 2 O ( 68 % HCl ), HCl?H 2 O ( 51 % HCl ), HCl?H 2 O ( 41 % HCl ), HCl?H 2 O ( 25 % HCl ), and ice ( 0 % HCl ).
19.
The cathodes are prefabricated hollow metal shells with a small opening ( sometimes a ceramic donut aperture ) which contains in the interior surface of the shell a light dusting of a cold cathode low work function powder ( usually a powder ceramic molar eutectic point mixture including BaCO 2 ), combined with other alkaline earth oxides, which reduces to BaO 2 when heated to about 500 degrees F, and reduces the work function of the electrode for cathodic emission.
