Heat-radiating ceramics

N-9H and N-6H, mainly made from alumina, are categorized in this group.
These materials have a high thermal emissivity, and they are applied to new types of heat sinks utilizing heat radiation.

Cordierite

-This ceramic is MgO・Al2O3・SiO2 kind, and it’s consist on 2MgO・2Al2O3・5SiO2 which is cordierite crystal. This material have two type, called N-23 and N-53.
-Especially, N-53 has much Nishimuras originality. The N-53s special feature is surface which is like after glazed.

Nishimura Original ceramics (Zirconcordierite)

-Zircon(ZrO2・SiO2)is one of the material which has good thermal shock resistance.
-We mixed this zircon with cordierite. This ceramics advantages are better resistance of thermal shock and stabler firing shrinkage.

Mullite

Mullite has high intensity as a alumina ceramic in room temperature. Also it is strong to high temperature condition, and it has small CTE.

For further details on Mullite, click here.

Porcelain (Standerd Porcelain)

This SiO2 and Al2O3 kinds ceramic is the most popular and low cost material.
As a high tension insulator, it is used for suspension-type insulator, pin-type insulator, or bushing. Also it is used for home appliance heater supporter, porcelain bushing, plug, socket, and wiring parts as a low or middle tension insulator. In case of  it is used in outside, we will coat its by a glaze.
