Hot isostatic pressing at 2200° C. and 30 KSI (206.8 MPa) argon pressure for two hours produces a bulk density of 2.10 g/cc. Complex shapes can be made. US5336520A - High density-high purity graphite prepared by hot isostatic pressing in refractory metal containers - Google Patents
Solid solution, high density (low porosity) samples greater than 95% TD were processed by cold pressing at 150 MPa and sintering above 2600 K for times longer than 90 min. Some impurity oxide phases were noted in some samples attributed to residual gases in the furnace during processing.
Table 1 shows the SiC monoliths sintered at 5 GPa have high densities and excellent mechanical properties, although the sintering temperatures (1100-1200 °C) are low compared to conventional processing methods and HTPVT,,,,, as the aforementioned hot-pressed SiC monolith at 1900 °C/50 MPa shows only a relative density of 66.5±2.0%.
vacuum oven, mixed and sintered. The results were much improved but still showed some significant porosity and again thick, cementite networks . From Figure 4, it easy to see graphite and silicon blocking porosity at 600ºC and preventing gases from escaping. Figure 5 shows that the graphite has just started to react but not

However, because the typical temperature in the vacuum furnace is below than 1500°C, the molybdenum has been approved to be the most promising material to explore in further as furnace components. The vacuum or high temperature furnace parts made of molybdenum include but are not limited to the following types:
Moly's high melting point and low vapor pressure at extreme temperatures justify its applications to cold wall vacuum or inert atmosphere furnace equipment. These properties, as well as Moly's high thermal conductivity and good electrical and chemical properties, lead to applications in glass-making manufacture of fibers and containers.
We have collected a number of charts detailing applications and properties for some of the most commonly used ceramic materials. While the data in these charts is, in most cases, typical of what you will find from ceramic component suppliers, it is only intended to be a general point of reference.
