Exhibit Highlights

Thin, highly crystalline boron nitride nanotube

BNNT, similarly as Carbon Nanotube (CNT), has high rigidity and high thermal conductivity, as well as unique properties not found in CNT, such as high-temperature oxidation resistance, insulation, piezoelectricity, and radiation shielding. It is possible to improve the properties significantly and add new functions by adding a small amount of BNNT to various kind of materials.

Boron Nitride Nanotube(R&D product)

BNNT has a very thin average diameter of 5 nm and high crystallinity. The BNNT does not contain any metal components. However, BNNT synthetics contains about 25 % boron particles which can be removed by oxidation heat treatment easily. In addition, we are developing a high purity BNNT that contains almost no byproducts of boron nitride component.
