Methods of making a ceramic of a Group 13-15 type or a Group 13-15-16 type by thermolyzing a discrete molecular precursor to the ceramic in an oxygen-containing atmosphere. In some embodiments, the discrete molecular precursor is bench-stable and comprises a Lewis acid-base pair or small cyclic compound containing at last one Group 13 element and at least one Group 15 element but does not include indium and phosphorus in combination with one another unless a Group 16 element is present. The thermolysis can be carried out in air, at atmospheric pressure, and at a temperature below about 400° C., if desired. In some embodiments, the discrete molecular precursor can be placed in a mold having a desired shape and the thermolysis performed while the discrete molecular precursor is in the mold so as to produce a ceramic product having the desired shape.

The present disclosure provides a method for preparing a multi-layer hexagonal boron nitride film, including: preparing a substrate; preparing a boron-containing solid catalyst, and disposing the boron-containing solid catalyst on the substrate; annealing the boron-containing solid catalyst to melt the boron-containing solid catalyst; feeding a nitrogen-containing gas and a protecting gas to an atmosphere in which the melted boron-containing solid catalyst resides, the nitrogen-containing gas reacts with the boron-containing solid catalyst to form the multi-layer hexagonal boron nitride film on a surface of the substrate. The method for preparing a multi-layer hexagonal boron nitride film can prepare a hexagonal boron nitride film having a lateral size in the order of inches and a thickness from several nanometers to several hundred nanometers on the surface of the substrate, providing a favorable basis for the application of hexagonal boron nitride in the field of two-dimensional material devices.

Disclosed herein are processes for purifying as-synthesized boron nitride nanotube (BNNT) material to remove impurities of boron, amorphous boron nitride (a-BN), hexagonal boron nitride (h-BN) nanocages, h-BN nanosheets, and carbon-containing compounds. The processes include heating the BNNT materials at different temperatures in the presence of inert gas and a hydrogen feedstock or in the presence of oxygen.
