95% black alumina ceramics, black in appearance, with properties similar to those of traditional alumina ceramics, and a microscopic porous structure, referred to as “black ceramics”.

Like traditional alumina ceramics, 95% black alumina ceramics have excellent properties such as good insulating properties, small expansion coefficient, high thermal conductivity, high mechanical strength, good light protection, wear resistance and low dielectric loss. Due to its unique properties, it has received widespread attention and attracted more researchers to develop and study it. In the future, the application of 95% black alumina ceramics in air pollution control, molten metal filtration is already a possibility.

Although 95% black alumina ceramics have unique and excellent performance, but because of itself is a porous product, so 95% black alumina ceramics itself exists a greater brittleness, sintering molding process often produces a more serious cracks, these performances to a large extent limit the 95% black alumina ceramics application and popularity. Therefore, in the research industry, this problem has long been plagued by researchers, but the development so far, did not find any effective and obvious improvement methods, if still can not find a solution in time, then its use will certainly be affected.

At present, in the market of ceramic preparation, there can be many ways to toughen black corundum ceramics, the more common ones are particle toughening, toughening transformation, and adding an appropriate amount of ductility in its toughening. On the surface of the laser, to promote its performance, in 95% black alumina ceramics design, should also look for new ways and means.

95% black alumina ceramic substrates are mostly used in semiconductor integrated circuits and electronic products. This is mainly due to the high light sensitivity of most electronic products. The packaging material needs to have strong light-shielding properties to ensure the clarity of the digital display. It is packaged with 95% black alumina ceramic substrate. With the continuous renewal of modern electronic components, the demand for 95% black alumina packaging substrate is also expanding. At present, domestic and foreign countries are actively carrying out 95% black alumina ceramic manufacturing process research.

The 95% black alumina ceramic fiberboard for electronics packaging is based on the needs of its application area. The selection of the black coloring material needs to be combined with the properties of the ceramic raw material. For example, the need for better electrical insulation of the ceramic material needs to be considered. Therefore, black coloring materials must take into account electrical insulation, thermal insulation and electronic properties in addition to the final coloring and mechanical strength of the ceramic substrate. Other functions of the packaging material. During the ceramic coloring process, the low temperature environment may affect the volatility of the coloring material and keep it warm for a certain period of time. During this process, free coloring materials may aggregate into spinel compounds, preventing the coloring materials from continuing to exist in a high-temperature environment. Volatility ensures the coloring effect.

95% black alumina ceramics can be used in semiconductor integrated circuits and electronic products, in addition to electronic bases, ceramic metallization, ceramic heating pads for hair straighteners, ceramic heating rods for faucets, and food processing machines and equipment.

With the continuous improvement and development of science and technology and related ceramics, in the near future, 95% black alumina ceramic brittleness problem will certainly be solved in time, and its own porous properties in alumina ceramics will be more widely used.
