和玻璃封接用的鉻鐵合金是含鉻28%的鉻鐵合金，又稱做高鉻鋼或28號膨脹合金。合金中由于加入了鉻，使膨脹系數(shù)降低，因此可與軟玻璃進行匹配封接。含鉻量高的鉻鐵合金，一般在室溫至熔點溫度的全部范圍內將是鐵氧體的狀態(tài)，所以也稱做鐵氧體的鉻鐵合金。封接前需在濕氫中加熱到950℃，薄而致密的CrO3及Fe2O3的氧化層，這種氧化層能很好地溶入玻璃并形成草綠色或褐綠色的封接面。合金特點是含鉻量大于28%，因而相變點特別高。<br /> 鐵鎳鈷玻璃封接合金<br /> 這種合金屬于精密合金，又稱可伐。它是鐵、鎳、鈷的合金，一般含鎳29%，鈷18%，其余是鐵。其膨脹系數(shù)由于鈷的加入而降低，與鉬及硬玻璃相近，適合于和硬玻璃作匹配封接。封接時表面生成有氧化鉆的氧化層，而氧化鈷極易溶于玻璃中而形成鼠灰色的封接面。當氧氣不足時，由于氧化層幾乎全部溶入玻璃而使封接面呈金屬本身的銀白色，雖不漏氣，但強度很差。氧化過度時，則因氧化層太厚而呈深灰色甚至黑色，易造成漏氣。<br /> 鐵鎳鈷陶瓷封接合金<br /> 這種合金屬于精密合金，也是鐵、鎳、鈷的合金，又稱為陶瓷可伐。在-60-600℃時它的膨脹系數(shù)與95%氧化鋁陶瓷相近，常用來和陶瓷作匹配封接。在金屬陶瓷發(fā)射管、行波管、速調管等器件和真空電容器中，鐵鎳鉆陶瓷封接合金廣泛地用來制作引出線、引出環(huán)、管殼等零件。</div><p><img
