Ammonium paratungstate (APT) was reduced in inductively coupled h.f. plasma reactor(4 MHz,2 kW). As working gas was used hydrogen. If the mixture of hydrogen with hydrocarbon is used (methane, propan butane)it is possible to prepare also tungsten car

Three boron nitride processes have been studied—synthesis of turbostratic powder, sintering of hexagonal ceramics and transformation into diamond-like phases. It is shown that the crystallization of boron nitride proceeds in three distinctive steps

A reaction mechanism of formation and growth of hexagonal boron nitride planar macromoleukules during reductive nitridation of oxidic boron compounds has been proposed. This model was verified by a comparison of computed values of oxygen contents wit
