High Temperature Co Fired Ceramic Process

The ceramic refractory metal composite structure is sintered or co fired at temperatures as high as 1 600ºc in a carefully controlled atmosphere.

High temperature co fired ceramic process.

Adtech ceramics manufactures its proprietary htcc blend which allows for hermetic straight through vias and dense metal interconnects. The temperature needed to transform soft clay into hard ceramic is extremely high and is usually provided by a kiln. If you re looking for a medium sized high fire kiln we d recommend the evenheat hf 2318. At 1832 f 1000 c the clay crystals begin to break down and melt.

Co fired ceramic packages are fabricated through four distinct processing stages that include material preparation green processing sintering and post fire processing. You cannot fire pottery in a home oven because ovens do not get up to the high temperatures of more than 1 500 degrees fahrenheit that you need for firing clay. If you re looking for a small high fire kiln we d recommend the evenheat hf 1413. Co firing can be divided into low temperature ltcc and high temperature htcc applications.

Low temperature means that the sintering temperature is below 1 000 c 1 830 f while high temperature is around 1 600 c 2 910 f. Whilst it offers many advantages in terms of the geometries that can be achieved restrictions include the limitations on some dimensions i e. Thicknesses and gaps by dried tape thickness which is prescribed by the. Hot pressed aluminum nitride is physically constrained in the x and y dimensions so all shrinkage occurs in the z dimension.

High temperature co fired ceramic htcc is a popular material choice for hermetic packaging due to its desirable electrical properties high mechanical strength and good thermal conductivity. All of these kilns will reach at least cone 10 2350 f and will be perfect for your high firing kilns. High temperature cofired ceramic htcc. 90 aluminum oxide ceramic tungsten metallization molymanganese metallization kovar sealrings leads pins design miniaturization advantage mechanical shock advantage weight advantage glass to metal seal gtms kovar housing corning 7052 glass seals lower cost advantage.

Adtech ceramics htcc packages are most commonly used in military aerospace medical device and high temperature applications. And if you re ready to get some real work done. Individual tapes are then bonded together in a lamination procedure before the devices are fired in a kiln where the polymer part of the tape is combusted and the ceramic particles sinter together forming a hard and dense ceramic component. High temperature co fired ceramics is more chemically and mechanically resistant can withstand higher temperature of work and storage and has significantly one order of magnitude higher thermal conductivity.

We offer a variety of high fire kilns at soul ceramics. The fired clay is known as metakaolin.
