Abstract
กระบวนการสำหรับผลิตสารผงของโลหะวาล์ว โดยเฉพาะอย่างยิ่งสารผงของ นิโอเบียมและแทนทาล์ม โดยการรีดิวซ์สารผงของออกไซด์ของโลหะว าล์วที่ตรงกันโดยใช้ โลหะรีดิวซ์ และ/หรือไฮโดร์ดของโลหะนั้นที่ เป็นไอโดยที่เสนอให้ทำขณะที่มีแกสพาหะที่เป็น แกสเฉื่อยอยู่ด้ว ย ซึ่งการรีดิวซ์ได้รับการดำเนินการที่ความดันย่อยของไอของโลหะ รีดิวซ์/ โลหะไฮไดร์ดที่เท่ากับ 5 ถึง 110 hPa และความดันโดยรวมต่ำ กว่า 1000 hPa และสารผงของ แทนทาล์มที่เตรียมได้โดยวิธีนี้มีความเสถ ียรของอนุภาครวมกลุ่มที่เป็นสารผงสูง Process for the powder production of metal valves Especially the powdered substance of Niobium and Tantalm By reducing the powdered substance of the metal oxide Matching valves using reducing metals and / or their hydrodes at It is a vapor that is suggested to do while having a gas carrier There is an inert gas where the reduction is performed at the vapor fraction pressure of the reducing metal / metal hydride equal to 5 to 110 hPa and the overall pressures below 1000 hPa and the powder substitute. The talm prepared by this method has a high stability High powdered aggregate particles
