Description

Verfahren zur Herstellung hochfeuerfester Körper. Es ist bereits bekannt, hochfeuerfeste Gegenstände aus einer Mischung von Zirkonerde , mit Siliziumkarbid herzustellen. - Die so her- I gestellten Fabrikate haben aber in der Praxis manche Nachteile gezeigt, da dieselben bei hoher Hitze zu leicht weich werden und ihre Form ändern. Hierdurch ist die Möglichkeit gegeben, daß die Schlackenangriffe und chemischen Einflüsse ungünstig auf das Material I einwirken.Process for the production of highly refractory bodies. It is already known highly refractory items made from a mixture of zirconia and silicon carbide to manufacture. - In practice, however, the products manufactured in this way have some Disadvantages shown as the same too easily soften at high heat and theirs Change shape. This gives the possibility that the slag attacks and chemical influences have an unfavorable effect on material I.

Diese Übelstände werden beseitigt durch Zusatz von Quarz. Das Material bleibt in der höchsten Hitze fest und bietet so den besten @@%iderstand gegen Schlackenangriffe und chemische Einflüsse. Hierbei ist zu bemerken, daß unter Quarz alle in der Natur vorkommenden Quarzite, Kiese, Sande usw. zu verstehen sind.These inconveniences are eliminated by adding quartz. The material remains solid in the highest heat and thus offers the best @@% resistance to slag attacks and chemical influences. It should be noted here that under quartz all in nature occurring quartzites, gravel, sands etc. are to be understood.
