TEXT: The - nurif ication Of Si 14 by recrystallizatioii from
n-heptane, was examin;d-in' detall. Si14 was synthesized directly
"from the elements at 65000. It 'was established th&t the majority of
the impurities in crude,Sil4 were coneentrated on thercsidue of sili-
ca gtl which was separAted by, hot filtration.. I 'A method was dtveloped
which permitted an advanced purification, of the' Si14 by the introduc-
tion of wet silica gel j'nt.o the n-heptane. solution, or by the forma-
tion of the. gel in situ -when wet-142 was bubbled through the solution.
The latter niethod was to be preferied because no edditional impurities
were introduced and.because bubbling accelerated the dissolution and.
homogenization of the solution. it was found.that 2 g silica gel per
liter of a-heptane was suf f icient for. a. good purification, and that
no special control was -necessary in the case Of N2 bubbling. The

TITLE: Manufacture of high-purity Si by means of the SiJ 4. method
PERIODICAL- Revista de chiintie, v. 12, no. 3, 1961, 137-143
TEXT: The aim of this work is to provide the necessary technological
data for producing transistor grade Si. The SiJ 4 method was chosen be-
cause of the efficient means available for purifying the intermediate.
Specifically, this method comprises 3 steps: (a) Synthesis of SiJ 4.
12 (99.8% pure) and Si(99.9% pure, obiained by treating a commercial
grade with HCl and HCl/HF) were directly combined in a laboratory scale
apparatus similar to that of G.J. Szekely (Ref. 1: J. Electrochem. Soc.
1957, v. 104, 663). It consisted of a quartz J 2 boiler, a vertical

synthesis tube (juartz) and a SW 4 receiver. The J 2 vapors were produced
by argon which was previously purified by passing it over CaH 2 at 3500C.
CuO at 6500C, Ng(CIO 4)2 and P205 and finally over glass spheres coated
with silicon grease. The same installation was used also on a larger
scale. The influence of temperature on purity and yield of SiJ 4 was in-
vestigated at 500-900 0C, using 'a charge of 100 g of J2heated to 190OC;
230g of Si packed in a column of 20 cm; 15 1/hr of argon; and a duration
Of synthesis of 2 hours. The optimum, attained at 700 0C gave a yield of
98.8% of Sij4 analyzing 5ol6% Si,---110-3% Ca, Al and no Ti, Fe, Cu. The
beat J2/Si ratio at this temperature was found by varying separately the
temperature of the J 2 boiler and the height of the Si column. The optimum
combination was found to be 1900C and 20 em respectively. (b) Purification
Of SiJ4 - (1) The crystallization Of SiJ4 from n-heptane, using an
8-fold molar excess of solvent, proved satisfactory LAbstractor's note:

Nature of the amelioration not clearly stated 1 (2) Alternatively, SO 4
was purifie&by distillation in ag inert atmosphere. The charge of
2 kg heated in an air bath at 315 C, was distilled by means of a heated
column made of quartz 1600 nui high and 30 mm wide, filled with Mo wire
and pr8vided with a magnetic reflux regulator. At a column temperature
of 305 C a reflux ratio of 1/3 to 1/5 and al fractionation efficiency of
10 theoretical plates, a product was obtained, the middle fraction
(60%) of which contains only 10-8% B and 10-4% Ca. The residue con_
tained up to 10-2% B. This enrichment is probably due to the formation
of B-complexes. (c) Thermal d.e"mposition of SiJ4 in vacuo. SiJ 4 was
charged through a side-arm into a I lit. quartz vessel heated by an oil
bath. The vapors of SiJ 4 passed int o a horizontal "suprasil" quartz
tube, protected by another quartz tube and heated to 10500C. Silicon is
compactly deposited on the "suprasil" tubes while the J 2 vapors are
subsequently trapped. The whole system was evacuated to 5.10-5 - 1.10-5

consumption of Sij 4* A spectrally pure Si is obtained. Activation
analysis showed up to 10 -5 oJr As, and Si from previously crystallized
material contained only 10 8% of B. There are 6 figures, 7 tables and
