Since entering the vacuum furnace industry, starting with the imitating manufacture of imported vacuum furnaces, Thermvac has been walking a single path as a pioneer in developing domestically the production vacuum-furnaces, such as one step dewaxing/sintering furnace, gas pressure sintering furnace, multi-crystal ingot grower for solar cell
2016-5-4 · alumina, zirconia. During rolling of vessel, the grinding media amp; powder particles roll from some height. This process grinds the powder materials by impact/collision amp; attrition. • Milling can be dry milling or wet milling. In dry milling, about 25 vol% of powder is added along with about 1 wt% of a lubricant such as stearic or oleic acid.
Then, the zirconia powder was applied onto titanium powder and sintered by means of pressure-assisted sintering process (HP), using a high frequency induction furnace, as schematically represented in Fig. 3. The mould was placed inside the chamber, where both pressure and temperature were increased till reaching the targeted values.
2019-7-9 · Description: KJ series of crucible furnace is composed by quartz crucible or alumina crucible and stainless steel flange .Working temperature ranges from 800℃ to 1200℃. It is mainly used for calcination of high pure compound in the vacuum or inert atmosphere; sintering or spread of semiconductor film, sinter of ceramic material, etc.
2016-11-9 · The high humidity in the chamber slowed down the drying rate to avoid warpage and crack formation. The green parts were then sintered in an electric furnace under atmospheric pressure to obtain the final parts. In order to determine the right sintering temperature vs. time, a sintering study was performed on the zirconia beams.
