氧化铝在电子工业中的应用?
多芯片式封装用陶瓷多层基板,封装用的纳米氧化铝陶瓷多层基板的制造方法有厚膜印刷法、生坯叠片法、生坯印刷法、厚薄膜混合法等四种。
高压钠灯发光管由多晶不透明的高纯纳米氧化铝所形成的纳米氧化铝透明体,应用于高压钠灯发光管,照明效率为水银灯的两倍,从而开拓了提高照明效率的新途径。
透明高纯纳米氧化铝精细陶瓷不仅能透光,而且具有耐高温、耐腐蚀、高缘、高强度、介质损耗小等性能,是一种优良的光学陶瓷,还可作微波炉窗等。
纳米氧化铝陶瓷传感器:用高纯纳米氧化铝陶瓷的晶粒、晶界、气孔等结构特征和特性作敏感元件,用于高温和含腐蚀性气体的环境中,使检测、控制的信息准确而迅速。
从应用的类型看,有温度、气体、温度等传感器。
Ceramic multilayer substrate for multi chip packaging. The manufacturing methods of nano alumina ceramic multilayer substrate for packaging include thick film printing method, green lamination method, green printing method and thick film mixing method.
The luminescent tube of high-pressure sodium lamp is a nano alumina transparent body formed by polycrystalline opaque high-purity nano alumina. When applied to the luminescent tube of high-pressure sodium lamp, the lighting efficiency is twice that of mercury lamp, thus opening up a new way to improve the lighting efficiency.
Transparent high-purity nano alumina fine ceramics can not only transmit light, but also have the properties of high temperature resistance, corrosion resistance, high insulation, high strength and low dielectric loss. It is an excellent optical ceramics and can also be used as microwave oven windows.
Nano alumina ceramic sensor: using the structural characteristics and characteristics of high-purity nano alumina ceramics such as grain, grain boundary and pore as sensitive elements, it is used in the environment of high temperature and corrosive gas to make the information of detection and control accurate and rapid.
From the type of application, there are temperature, gas, temperature and other sensors.
