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.
