Medical ceramics

High strength, High purity Alumina ceramics N-9000NS and N-9000T

Nishimura Advanced ceramics cooperated with the Medical analysis device industry for a long time, and we have succeeded to develop a special material for the medical industry. N-9000NS / N-9000T‘s average crystal size is under 1μm and those materials own 1.5~2 times higher intensity.

The reason why this material is suitable for the medical industry

(1)Excellent durability

This material has excellent wear resistance (Vickers hardness 21.4 GPa), product life will be increased.

(2)Unbreakable

Bending strength, Compressive strength, Tensile strength is extremely high. It is the most suitable material for precision parts.
N-9000NS has similar/better material properties like Sapphire.

(3)Gentle for blood, easy to wash

Crystal size is under 1 µm which is an extremely smooth surface. 
Since a red blood cell size is approx. 5 µm, it won’t be stuck on an Alumina crystal.
It’s very easy to wash, so this material is suitable for parts/tool which needs to be hygienic and repeatedly usable.

(4)Chemical Resistance

The high purity Alumina material stands for most of Acid or Alkali. Especially N-9000NS and N-9000T has excellent chemical resistance.

(5)Plasma Resistance

This material is used as a plasma resistance material. Since Alumina purity of this material is very high(Al2O3>99.99%), grain boundary segmentation won’t occur.

(6)Excellent Insulation

Since this material doesn’t contain many impurities, dielectric breakdown voltage and volume resistivity are very high which means it has an outstanding thermal resistance and great insulation at high temperatures.
