Chemical vapor deposited isotropic boron nitride is formed on the inner walls of a reaction chamber by forming a vapor mixture of an oxygen containing organic boron compound with ammonia and reacting the vapor mixture in said reaction chamber at about 1100 degrees C. to about 1900 degrees C. at pressures of about one torr to atmospheric.

The properties, such as density and dielectric constant, of materials prepared by the CVD depend upon reaction parameters, such as pressure and temperature. The degree of anistropy of the CVD products depends primarily upon the initial reactants and secondarily upon the reaction parameters of temperature and pressure. In the report the preparation of anistropic and isotropic boron nitride (BN) is described. Two methods of preparation of the anistropic material have been investigated. One method uses ammonia and boron trichloride as the starting materials while the second method begins with beta-trichloroborazole. It will be shown that beta-trichloroborazole is a logical intermediate of the ammonia-boron trichloride system and that the two methods are, therefore, essentially equivalent. A theory is presented that not only accounts for the fact that BN formation occurs only at the hot substrate but is capable of predicting the requirements for the formation of the isotropic or anistropic forms. It should be shown that at the hot substrate a surface reaction takes place that results in the deposition of BN in an ordered anistropic form. In the reaction used for the formation of anistropic BN, water vapor is not present to disturb the initial anistropy. (Author).

Boron nitride was first produced in the 18th century and, by virtue of its extraordinary mechanical strength, has found extensive application in industrial processes since the 1940s. However, the more recent discovery that boron nitride allotropes are as structurally diverse as those of carbon (e.g. fullerenes, graphene, carbon nanotubes) has placed this material, and particularly its low-dimensional allotropes, back at the forefront of modern material science. This book provides a comprehensive history of this rapid rise in the status of boron nitride and boron nitride nanomaterials, spanning the earliest examples of three-dimensional boron nitride allotropes, through to contemporary structures such as monolayer hexagonal boron nitride, boron nitride nanomeshes, boron nitride nanotubes and the incorporation of boron nitride into cutting-edge van der Waals heterostructures. It specifically focuses on the properties, applications and synthesis techniques for each of these allotropes and examines how the evolution in boron nitride production methods is linked to that in our understanding of how low-dimensional nanomaterials self-assemble, or ‘grow’, during synthesis. The book demonstrates the key synergy between growth mechanisms and the development of new, advanced nanostructured materials.
