Boron nitride nanotube (BNNT) has a similar tubular nanostructure as carbon nanotube (CNT) in which boron and nitrogen atoms are arranged in a hexagonal network. Owing to the unique atomic structure, BNNT has numerous excellent intrinsic properties, such as superior mechanical strength, high thermal conductivity, electrically insulating behavior, piezoelectric property, neutron shielding capability, and oxidation resistance. Since BNNT was first synthesized in 1995, developing an efficient BNNT production route has been a significant issue due to low yield and poor quality in comparison with CNT, thus limiting its practical uses. However, many great successes in BNNT synthesis have been achieved in recent years, enabling access to this material and paving the way for developing promising applications. In this article, we discussed the current progress in producing boron nitride nanotube, focusing on the most common and effective methods that have been well established. In addition, we presented various applications of BNNT, including polymer composite reinforcement, thermal management packages, piezo actuators, and neutron shielding nanomaterial. A material's outstanding and exceptional physical properties can emerge when its size reduces to the nanoscale. Developing nanostructures possessing unique features has been the essence of nanoscience and nanotechnology since the beginning. Among various nanostructures in general and all kinds of one-dimensional networks, nanotubes have built a strong reputation as the most widely studied nanomaterial. Take carbon nanotube as an example; theoretical and experimental research in every aspect of tubular nanostructure has flourished since CNT's first discovery in the early 1990s. CNTs offer numerous fascinating applications in electronics, sensing, composite, and many more that are being progressed. Developing a new class of nanotubes beside the famous carbon allotrope has become an attractive topic in recent years.
