ment has practically no effect on the overall thermal conductivity even at hi~~h
temperatures so that the expression for the electron thermal conductivity can be used!
with sufficient accuracy to represent the total conductivity. The author thanks

ABSTRACT: This paper gives an account of the findings concerning
the stability of highly refractory materials in the checker
chamber of a plant. The checker works in 2 cycles which
alternate every two minutes. In the first cycle, the checker
chamber is heated by the combustion of methane up to a
temperature of 1750 _ 1800 0, wherea", an oxidation medium
is existing. In the second cycle iLethane, hydrogen, and
carbon act in a re6eneration medium the temT)erature falling
to 1500-16000v in the coldest part of the checker chamber
at cycle change even down to 1500-13000. The following
refractories were tested in a sm-11 testing plant:1) re-
fractories on the basis of recrystallized alumina comprising

All tested materials on t'-,e basis of pure oxides proved to be
insufficiently st:-Jhle, as is seen from figures 1,2,and 3.
Only refractories on the basis of carb=urdum Gave satisfactory
results (F-'Zs 4,5). It was found that the carborundum
materials which are stable against the conditions of re-
generation are to be re-garded as suitable for the checker
chamber. A definite selection of the most proper tvpe of
carborundum cj-.eck_-rs will not be possible before extended
investigations are accomplished. There are 5 fig'Ures and
3 references, 2 of which are Soviet.

TITIZ: Manufacture of sintered ceramics from magnesium oxide
PER10DICAL: OgneuPO711no- 3, 1961, 123-124
TEXT: This article describes the process of manufacturing thin-walled,
sintered crucibles and shield tubes for thermocouples from magnesium
oxide. This process was elaborated at the Podol'skiy zavod ogneupornykh
izdeliy (Podollsk Plant for Refractories) jointly with the kafedra
keramiki (Der)artment of CeraTnics) of the Khimiko-tekhnologicheskiy
institut im. Mendeleyeva (Institute of Chemical Technology imeni
Mendeleyev). The crucibles are intended for metal smelting. The initial
material was commercial magnesium oxide 'with a content of 98% MgO,
the preparatiiq of which (firing temperature and mode of crushing) was
,t o r1k L
- -d out according to previous studies. Commercial magnesiun. in powdery
form is first fired in molds at 13000C and then finely ground in a
vibrating mill by means of steel balls. The powder was plasticized by

means of paraMn with an addition of oleic acid. The shaping of
crucLbles and shield tubes for thermocouples from magneslun oxide by the
"freezing-on" method permits the manufacture of products with a wall
thickness of 5-0.3 mm. After Partial burning out of the paraffin at a
temperature of about 2000C, the products were fired in a regenerative
medi,am (H2) at 17000C in an electric 'Lurnqce with a molybdenum coil.
The firing time was 5 to 6 hr (2 hr in the high-temperature zone). After
sintering the average weight by volume of the products was 3.36 to
3.38 g/cm and their apparent porosity 0 to 0.4 ;-v; the white products
showed good tr~inslucence. Pyrometric ceramics produced from magnesium
oxide in the f orm of shield tuves for thermocouples and capillary tubes,
permits temperature measurement up to more than 20000C. The relatively
simply process permi-ts the manufacture of products for use at high
temperatures, the waste being ver-j small. There are 1 figure and 1
Soviet-bloc reference.

corundum, zirconium dioxide., zircon, calcium zirconate, and silicon nitride were
affected considerably by lithium, particularly in contact with melted lithium; (2)
ina,3nesium oxide and calcium oxide showed greater chemical stability; (3) the chem-
ical stability of magnesium oxide 'with A1203 admixtures vas noticeably less than
that of pure magnesium oxide; (4) the carbor~ndun samples on a bond of P -carborun-
dum did not posseEsthe required electroinsulatiT properties; (5) boron nitride-

fractory materials of pure-aluminum oxide and pure zirconium dioxide, zircon, cal-
ciun zirccnate and silicon nitride are not serviceable because of their low
chemical stability; however, boron nitride., calcium oxide, and magnesium oxide may
be used as insulators. Orig. art. has : 8 figures, 2 tablqse

porous products can be controlled over a wide range by varying the

ABSTRACT: Results are reported fron the study of production and properties of
periclase refractories made of technical 99,":, NgO in the form of grains of sintered
briouets. Sintered briquetting material was crushed, freed of iron in-p=-ities, and
sieved. A fraction of < 0.5 = was grou:nd to obtain grain size < D.Co' mm, which
was pressed into cylinders 36 mm. in diameter and 50 = high. The specimens were
fired at 1730C for 1 or 4 hours. The porosity of the samples was 17-11~r,.; they
m-intained a constant volume at 1800C and possessed a higher thermal stability than
products made of sintered ~~aO. Introducing r,~ 8% of Al 0 increased considerably
2 3
the thermal stability (two to four times the number of thermal cycles). These
