多芯片式封裝用陶瓷多層基板，封裝用的納米氧化鋁陶瓷多層基板的制造方法有厚膜印刷法、生坯疊片法、生坯印刷法、厚薄膜混合法等四種。

高壓鈉燈發(fā)光管由多晶不透明的高純納米氧化鋁所形成的納米氧化鋁透明體，應(yīng)用于高壓鈉燈發(fā)光管，照明效率為水銀燈的兩倍，從而開(kāi)拓了提高照明效率的新途徑。

透明高純納米氧化鋁精細(xì)陶瓷不僅能透光，而且具有耐高溫、耐腐蝕、高緣、高強(qiáng)度、介質(zhì)損耗小等性能，是一種優(yōu)良的光學(xué)陶瓷，還可作微波爐窗等。

納米氧化鋁陶瓷傳感器：用高純納米氧化鋁陶瓷的晶粒、晶界、氣孔等結(jié)構(gòu)特征和特性作敏感元件，用于高溫和含腐蝕性氣體的環(huán)境中，使檢測(cè)、控制的信息準(zhǔn)確而迅速。

從應(yīng)用的類型看，有溫度、氣體、溫度等傳感器。

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.
