标题:Zeolites of the borosilicate type, containing fluorine
摘要:Process for the synthesis of zeolites of the borosilicate type of the family of pentasils having the formula: (O-1) M2/nO : B2O3 : x SiO2, wherein x varies between 20 and 1000 and M is a compensation cation of valence n and also containing fluorine. The process comprises: (a) the formation of a reaction medium having a pH lower than 10.5 and comprising particularly water, a silica source, a boron oxide source, a mobilizing agent source containing fluoride ions and a structuring agent source capable of providing cations selected among tetrapropylammonium cations (TPA+) and tetrapropylphosphonium cations (TPP+), (b) heating the reaction medium formed in step (a) to a temperature lower than 230oC till the obtention of cristalline compound, (c) calcining the obtained compound to a temperature higher than 450oC.

摘要:A non-aqueous route and process for preparation of boron nitride utilizing aerosol assisted vapor phase synthesis (AAVS) wherein boron precursors are nitrided in one or two heating steps, and wherein a boron oxide nitride carbide intermediary composition is formed after the first heating step and may be further nitrided to form resultant spheroidal boron nitride powders including spheroidal particles that are smooth, bladed, have protruding whiskers, and are of turbostratic or hexagonal crystalline structure, specifically wherein the boron precursor is dissolved in a non-aqueous solution prior to aerosolization.
