Es wurde gefunden, dass man an Stelle von Zement und Kalk auch Gips anwenden kann. Der künstliche Korund, die geschmolzene Tonerde wird gewonnen durch Schmelzen im elektrischen Ofen, im Knallgasgehliise oder anderen genügend heissen Hitzqucllon und kann auch andere Oxyde beigemengt enthalten.

Cooking for hours in concentrated alkali solutions is not affected, which is particularly important for the manufacture of alkali-resistant diaphragms. It has been found that plaster of paris can also be used instead of cement and lime. The artificial corundum, the molten alumina, is obtained by melting in an electric furnace, in an oxyhydrogen furnace or other sufficiently hot hot quench and can also contain other oxides.

and then has a firing temperature of Segerkegel 12.
2. When using quick lime as a binding agent:
40 parts by weight of artificial corundum, grain size 20 50 ",", 180 10, quicklime (Ca 0).

3. When using plaster of paris as a binding agent:
70 parts by weight of fused alumina (powdery flour)
30 "plaster of paris.
Firing temperature Seger cone 17.
Coatings on pieces of rchumotte are made, for example, from:
20 parts by weight of artificial corundum, grain size 18-40 55 # # # # 120-180 25 "Portland cement and burned on at Segerkegel 14.
All kinds of devices and vessels can be made from these masses by molding and firing. Brick and
