陶瓷等无机材料,硬度高、脆性大,通常是很难象金属那样将薄片样品冲压成透射电镜用的直径为ф3mm规则的圆片试样。陶瓷和其它硬质材料透射电镜试样的制备通常有如下步骤: 1 从大块材料中用超薄切片机(金刚石刀片)切成厚为0.1～0.3mm的薄片; 2 将薄片用低溶点蜡或其它粘结剂固定在支撑盘上:再用一空心钻(也称取芯钻)将薄片切成直径为 Ceramic and other inorganic materials, high hardness, high brittleness, it is usually difficult to metal sheet metal stamping sample into a diameter of ф3mm rules for the use of TEM sample of the wafer. Ceramic and other hard materials TEM samples are usually prepared as follows: 1 from the bulk material with a thin slicer (diamond blade) into a thickness of 0.1 ~ 0.3mm sheet; 2 the sheet with a low melting point Wax or other adhesive fixed to the support plate: Then use a hollow drill (also known as core drill) cut the sheet into a diameter of
