LaB6 單晶是一種特殊結(jié)構(gòu)的晶體，它具有金屬的良好導(dǎo)電性且逸出功低，工作在1400～1680℃時，可以獲得0～100A/cm2 的直流發(fā)射電流，遠勝于氧化物及純金屬陰極。
Kimball Physics公司（簡稱KPI公司）生產(chǎn)的六硼化鑭陰極特征如下：
l 更長的壽命：潔凈真空中上千小時的壽命
l 超常的穩(wěn)定性能：耐熱、化學(xué)、電、碳鍍、高溫等等
l 高亮度，低能耗：單晶LaB6,高品質(zhì)-高純度
Model ES-423E,單晶被加工成90°或者60°椎體，再根據(jù)微面分為15um、6um、20um平面等幾種。
