Tape casting is a low cost fabrication process for flat ceramic sheet and this paper demonstrates how it can be combined with vacuum forming to make α-alumina domes of 250-300 μm sintered thickness. The suspension formulation makes use of systems of double plasticizers and double solvents in a poly(methyl methacrylate) binder to provide plastic ceramic films by tape casting from which preforms for vacuum forming were cut. In order to retain the shape of vacuum formed domes during debinding and sintering, an initial low temperature anneal is needed. The study indicates that the ratio of plasticizers to binder and the particle size are two dominant parameters in influencing the elongational flow. The whole process provides a novel method to make thin ceramic domes. 相似文献

Conclusions A technology was developed for making large blanks of zirconium and niobium carbides. The technique includes slip preparation, preforming of the blanks by hot casting or hot extrusion, and hot die casting in vacuum at 2200°C.Using this method articles were made whose density was 96–97% of the theoretical. There were no internal defects according to ultrasonic control checks.Translated from Ogneupory, No. 6, pp. 49–52, June, 1967. 相似文献

A report is given on the production of periclase-carbon refractories using advanced technologies and raw periclase of different quality grade at the Semilukskii Refractory Plant Joint-Stock Company (SRP JSC). Refractories available from the SRP JSC were used at the Oskol'skii Electrical Iron and Steel Works JSC (OEISW JSC) to fabricate the multiple-purpose lining for casting ladles exploited in vacuum furnaces and integrated steel-processing units. The endurance of the lining for the walls and the slag zone of the casting ladle reaches 69 heats. 相似文献
