ทังสเตนคาร์ไบด์

อ่าน 1592678 | ตอบ 11690
ทังสเตนคาร์ไบด์
       ทังสเตนคาร์ไบด์ (อังกฤษ: tungsten carbide) มีสูตรเคมีคือ WC ในรูปพื้นฐานจะมีลักษณะเป็นผงสีเทาละเอียด มี 2 โครงสร้างคือแบบหกเหลี่ยม (α-WC) และแบบลูกบาศก์ (β-WC)
 
       ทังสเตนคาร์ไบด์เตรียมได้จากการทำปฏิกิริยาระหว่างทังสเตนกับคาร์บอนที่อุณหภูมิ 1400–2000 °C[3] หรือให้ความร้อนกับทังสเตนไตรออกไซด์และแกรไฟต์โดยตรงที่ 900 °C หรือในแก๊สไฮโดรเจนที่ 670 °C ตามด้วยการคาร์บิวไรเซชันในแก๊สอาร์กอนที่ 1000 °C[4] หรือใช้วิธีการเคลือบด้วยไอเคมี เช่น
  • ทำปฏิกิริยาระหว่างทังสเตนเฮกซะคลอไรด์กับไฮโดรเจนและมีเทนที่อุณหภูมิ 670 °C (1,238 °F)
 WCl6 + H2 + CH4 WC + 6 HCl
  • ทำปฏิกิริยาระหว่างทังสเตนเฮกซะฟลูออไรด์กับไฮโดรเจนและเมทานอลที่อุณหภูมิ 350 °C (662 °F)
                WF6 + 2 H2 + CH3OH → WC + 6 HF + H2O
       ทังสเตนคาร์ไบด์มีจุดหลอมเหลวที่ 2,870 °C (5,200 °F) และจุดเดือดที่ 6,000 °C (10,830 °F) มีความแข็งระดับ 9 ตามมาตราโมสและประมาณ 2600 ตามมาตราวิกเคอส์[5] ทังสเตนคาร์ไบด์มีความแข็งเกร็งมากกว่าเหล็กกล้าประมาณ 2 เท่า มีค่ามอดุลัสของยังประมาณ 530–700 GPa (77,000–102,000 ksi)[2][6][5][7] โมดูลัสของแรงบีบอัด 630–655 GPa และโมดูลัสของแรงเฉือน 274 GPa[8]
 
ด้วยคุณสมบัติความแข็งและทนความร้อนสูง ทังสเตนคาร์ไบด์จึงใช้ทำเป็นเครื่องมือตัดหรือหัวเจาะ ใช้ทำกระสุนเจาะเกราะ เครื่องมือผ่าตัด อุปกรณ์กีฬา เครื่องประดับและอื่น ๆ
