| 20110052440 | MANUFACTURE OF SINTERED SILICON ALLOY - Dehydration and drying of a silicon alloy argil which uses water as a principal binder are carried out by a freeze-drying process, a microwave irradiation process, or a combination thereof. In the freeze-drying process, the shaped compact is put into a cooling medium within 5 minutes after completion of shape forming, retained therein for at least 5 minutes to quick-freeze water within the compact while the water is still in a finely-dispersed condition. The compact is exposed to a pressure below the triple point pressure of water. In the microwave irradiation process, the shaped compact is put into a container exposed to continuous microwave irradiation at 2.450 GHz for at least 5 minutes while under a reduced pressure below atmospheric pressure. | 03-03-2011 |
| 20110105297 | DUPLEX EUTECTIC SILICON ALLOY, MANUFACTURING METHOD THEREOF, AND MANUFACTURING METHOD OF SINTERED COMPACT USING SILICON ALLOY POWDER - A duplex eutectic silicon alloy including 30-70 weight % silicon, 10-45 weight % nitrogen, 1-40 weight % aluminum, and 1-40 weight % oxygen has a eutectic structure comprising a β′-sialon phase and an ο′-sialon phase. The alloy is produced by controlling cooling at a rate of 50° C. or less per minute in combustion synthesis. A ductile sintered product capable of replacing steel in various applications can be produced by placing a compact composed of a powder of the alloy in a sintering furnace which can supply a heat quantity at least ten times the heat capacity of the compact; and sintering the compact at a pressure at least as great as atmospheric pressure, within a nitrogen atmosphere in which the silicon gas mole fraction is 10% or more, and at a temperature within the range from 1400° C. to 1700° C. | 05-05-2011 |
