無定形碳化硅 的英文怎麼說
中文拼音 [wúdìngxíngtànhuàguī]
無定形碳化硅
英文
amorphous carborundum-
Ammonia played a critical role in the vertical alignment of cnts, and the possible reason was that in 850 the atomic hydrogen decomposed from ammonia reacted with amorphous carbon to form volatile products to keep the metal surface clean, and mechanical leaning against neighboring tu bes established a morphology of vertical alignment
當基體為單晶硅、催化劑鎳膜厚度為20nm 、氨氣氣氛、生長溫度為850時,得到了定向生長的納米碳管。其原因可能是850時氨氣分解的氫原子和無定形炭生成了易揮發物質,從而保持催化劑的活性使納米碳管依靠相鄰碳管之間的斥力定向生長。Factors influencing pore structure of amorphous silica - alumina prepared by carbonization were investigated
