Movie on Alaska For
Biology Club Tuesday
“Alaska: A Perfect Paradise for
Hunters” is the title of a movie to
be shown in the Chemistry Lec
ture room Tuesday night, Febru
ary 11, at 7:30 o’clock, it was an
nounced today by W. E. Reifschla-
ger, vice president of the Texas
A. & M. Biology Club, under who’s
auspices the movie is being shown.
This picture, filmed in techni
color, was produced by the Gulf
Oil Corporation of Houston so that
the people of this country might
get a first hand idea of the magic
wonders of the great and vast
country known as Alaska.

Seniors to Plan
Summer Curricula
Plans for courses to be offered
in the Engineering school during
the summer sessions must begin
immediately, Dean H. W. Barlow
announced. There will be a
meeting of all seniors in engi
neering who contemplate gradua
ting in either of the summer ses
sions, at 5:00 p. m., Tuesday, Feb
ruary 11 in the Petroleum Lec
ture Room.
Each student in the above group
will be requested to make out a
card for each course which he ex
pects to take in the summer. In
order to prepare for this meeting
each student should check his
graduation plan with the Regis
trar so that he can furnish defin
ite information. No responsibility
will be assumed for those men who
do not attend the meeting with
the necessary information, it was
stated.
Barlow to Address
SAE Chapter Tues.
Dr. Howard Barlow, dean of
engineering, will address A.&M.’s
student S.A.E. Chapter Tuesday
evening, February 11, 7:00 p.m., in
the M.E. Lecture Room. His top
ic will be, “Why An Engineering
Society.” Dean Barlow, who takes
an active part in the functions of
the society in Texas, is the student
chairman of the Texas Section of
S.A.E.
• The talk will be of interest to
all engineering students and the
meeting is open to the public. A
special invitation is extended to
all freshmen and sophomore en
gineering students from the S.A.E.
mfembers.
Terry Clark, president of the
S.A.E. student chapter, announced
Wednesday that plans are being
made to bring two more speak
ers to the campus this spring. It
was also disclosed that an inspec
tion trip is expected to be made
in April.

Monday night saw a record set
for Attendance at a veteran stu
dent’s meeting on the A & M
Campus. The lower floor of Guion
Hall was packed, and late comers
were seated in the balcony.
The veterans were welcomed by
Gibb Gilchrist, president of the
college, who stressed the high
scholastic records made by stu
dents back from the war.
Taylor Wilkins, veterans advis
ors, explained the work of his
office in assisting veterans. J. R.
Varnell, contact representative of
the Veterans Administration in the
Bryan-College Station area, told
what matters are handled by his
office (everything but education)
and spoke of the work of the train
ing officers in Hart Hall, who
handle all educational matters.
Vamell’s office is in City Hall,
Bryan, but he is at Hart Hall
Monday mornings, Thursday after

nounced by bearded Bob Poison,
acting vice-president.

The “Whitest of White” Pigments from Black Ore
It is a strange fact that the ninth most
prevalent element in the earth’s crust
should have been regarded as "rare”
for over a hundred years after its dis
covery in 1791. But that is the story
of titanium, actually more abundant
than zinc, copper, lead, tin, and nickel
combined. One of the factors that have
kept titanium from being better known
is the difficulty of handling some of its
compounds commercially.
If, as a student, you were to look up
the equations for the manufacture of
titanium oxide pigment, you might find
something like this:
FeTiOs. nFe203*+ + i
+ FeS0 4 + nFe2(S0 4 )3 + (3n + 3)H 2 0
Fez (S0 4 ) 3 + 2H + >2FeS0 4 + H 2 S0 4
TKS0 4 ) 2 + (x-f2)H 2 0—>■ Ti0 2 .xH 2 0 + 2H 2 S0 4
Ti0 2 .xH 2 0—>TiG 2 + xH 2 Q
*—The exact composition of ilmenite
varies with the source of the ore.
From these equations, the manufac
ture of the "whitest of white” pigments
from black ilmenite ore appears to be
chemically simple and straightforward.
However, the processing required to
obtain industrial titanium oxide of
sufficient brightness, hiding power and
fineness is more complicated than one
would anticipate.
Controlling a Metastable System
The final product must have a particle
size averaging 0.2 microns in radius and
varying between 0.1 and 0.5 microns.

RADIUS IN MICRONS OF INDIVIDUAL PARTICLES OF TiO,
To attain this end in
a metastable system
that is ready to go in
the wrong direction
at any time requires
exceedingly rigid
control conditions
throughout.
The essential steps
in the operation are:
1) The careful solu
bilization of ilmenite
in concentrated sul
furic acid to avoid
hydrolysis. 2) The
complete reduction of
any ferric iron to fa
cilitate purification of
the solution, with re
moval of any uncon
verted residue and
colloidal slimes. 3)
Crystallization of 70
per cent of the iron as FeS04.7H20—
a critical operation in which tempera
ture must be kept low and wild seed
crystals avoided. 4) Hydrolysis around
105-109° C.—the most important step
of all—because the initial particle size
and pigment properties of the final
product depend on concentration, tem
perature, time of hydrolysis, intensity
of stirring, and presence of foreign ma
terials. In this operation it is not un
usual to talk in terms of parts per mil
lion, rather than the usual analytical
accuracy of 0.01-0.02 per cent. 5) Vary
ing salt treatment of the precipitate,
depending on the impurities. 6) Cal
cination between 900-1000° C. to obtain
the desired particle size. 7) Grinding to
give the proper aggregate size. 8) Treat
ment of the dried pigment in various
ways depending on end use; e.g., in the
automotive, rubber, ceramics, paper,
linoleum, printing, or other fields.
Wide Diversity of Research Problems
Long and patient research was neces
sary to develop the manufacturing tech
niques now used. Some of the problems
demanded technical skill of the highest
order from the colloid chemist, the phys
ical chemist, the analyst, the crystal-
lographer, the physicist, and other spe
cially trained men. A wide variety of
instruments, such as the petrographic
microscope, the electron microscope,
x-ray diffraction unit, ultra-centrifuge,
and spectrophotometer were used in

chemical engineer, the mechanical en

to design equipment to handle this ex

The manufacture of titanium pig
ments is another example of the prob
lems that constantly challenge chem
ists, engineers and other speciahsts.

SCHEDULE CHANGES
1. Any students desiring to add a course
must present a written statement from
the department concerned, that there
is a place in the class for him. This
statement must be presented to the
Dean of his School. With the Dean’s
approval, the Registrar will be auth
orized to make the change.
2. Transfers from one section to another
in the same subject will be made by
the department involved.
3. February 10th will be the last day
that courses can be dropped without
a grade. It will also be the last date
on which new courses may be added.

instruction and the handling of apparatus
in the laboratories. The scale of com
pensation is $25. per month for 10 hours
service per week and proportionate
amounts for more or fewer hours.
