Scopri l'uso di
zone refining nella seguente selezione bibliografica. Libri associati con
zone refining e piccoli estratti per contestualizzare il loro uso nella letteratura.
1
Principles of Solidification: An Introduction to Modern ...
Today, however, zone refining as a purification process is used primarily to
produce purified metals and semiconductor compounds, such as GaAs single
crystals for large-area device substrates. Zone refining of Si is still applied
commercially ...

Technology of Si, Ge, and SiC / Technologie Von Si, Ge und SiC
Purification is usually performed by the horizontal one-zone refining process (Fig.
55). Fig. 56a, b shows a schematic representation of the impurity distribution
obtained after zone refining a), and of impurity profiles of crystals (I- -111) b),
grown ...

Purification Process and Characterization of Ultra High ...
5.3.2 Zone Refining Zone refining is a good example of a purification technique
thought to be unsuited to the rare earths until the advent of UHV technology and
cold boats. The principle behind zone refining is the phenomenon whereby the ...

Th Zone Refining compaction technique resembles the process of zone refining
used for the purification of crystal ingots [PFAS2]. The zone refining process starts
with an already established crystal ingot This ingot is then slowly pulled through ...
Giovanni DeMicheli, P. Antognetti, Alberto Sangiovanni-Vincentelli, 1987

Solidification and Crystallization Processing in Metals and ...
Repeated fractional crystallization with close zones saves time as the processes
at all the zones occur nearly simultaneously with no interruptions for separation
of pure and impure fractions. The extreme process is continuous zone refining, ...

MATERIALS SCIENCE AND ENGINEERING: A FIRST COURSE
7.7 Other Applications of Phase Diagrams One of the important uses of a phase
diagram is in the zone refining of materials. Consider the schematic phase
diagram shown in Fig. 7.15. We need to purify (or refine) A, which has B as the
impurity ...

Figure 1 also illustrates that many of the critical impurities such as Cu, Fe, Ni, Co,
Ag, and Au do not segregate very effectively and that on this basis alone,
distillation should be preferred over zone refining. Further support for distillation
over ...
