Ceramic Substrate Material

Keral 99 is a high alumina substrate material with 99 7 purity.

Ceramic substrate material.

At present the ceramic substrate materials used include alumina beryllium oxide aluminum nitride silicon carbide and mullite. Ceramic materials include alumina al2o3 aluminum nitride aln and silicon nitride si3n4. The advantages of alumina include high resistivity good mechanical and dielectric strength excellent thermal and corrosion stability and the ability to provide hermetic seals. Substrates made from rubalit alumina ceramics rubalit 708 s with 96 al 2 o 3 this ceramic material is characterized by its extremely high strength and thermal conductivity.

The dielectric strength is the highest of kerafol s ceramic substrate materials. Ceramtec offers the world s top ceramic materials for thick and thin film technology and provides ceramics optimally designed to meet customer specification profiles.

Ceramic substrates corning s ceramic substrates launched a global clean air movement optimized for high performance efficiency and flexibility our advanced ceramic substrates can meet the most demanding gasoline and diesel system needs in both light duty and heavy duty applications. Ceramic substrates such as alumina aluminum nitride and beryllium oxide are highly thermally conductive materials which transfer heat away from hot spots quickly and efficiently dissipating it over the whole surface. Our range of ceramic substrates alumina substrate. The porous alumina substrates are often used as sintering base with the thermal treatment to 1500 c.

In terms of structure and manufacturing process ceramic substrates can be divided into high temperature co firing multi layer ceramic substrates low temperature co firing ceramic substrates thick film ceramic substrates etc. Zro 2 substrate have a high corrosion and abrasion resistance. Alumina and aln have been used for a long time as the standard substrate materials for fabricating electronic circuits in thick film technology. Aln substrate have a high oxidation and abrasion resistance.

We lasercut the material according to your wishes. The ceramic substrates include copper layers for fabrication of circuit patterns heat sinks and other electronic structures. Beside this conventional application these ceramics have been proved as excellent substrate materials for thick film heater employments.
