Рассчитаны удельная поверхность и  пористость порошков. Анализируются особенности изотерм адсорбции исследуемых  образцов до и после взаимодействия с водой с точки зрения соответствия их конкретному  типу согласно рекомендациям Международного союза по теоретической и прикладной химии (IUPAC), а также определенному виду пористости, что необходимо для понимания  области их дальнейшего применения. Обсуждается механизм взаимодействия порошка  нитрида алюминия с водой. Показано, что имеет место ионно-адсорбционный механизм с  формированием пористых агломератов, состоящих из нанопластин оксигидроксида  алюминия игольчато-пластинчатой формы, соединенных контактами, с диаметром пор 55 Å.  Удельная поверхность при этом возрастает с 48 до 115 м2/г. Установлено, что в результате  взаимодействия нанопорошка AlN с водной средой происходит изменение фазового состава  – продукты взаимодействия представлены фазами AlO(OH), Al(OH)3.</p></abstract><trans-abstract xml:lang="en"><p>The paper presents the results obtained when studying the adsorption and structural peculiarities of aluminum nitride nanopowder interaction with water, particularly the morphology and  phase composition of oxidation products. Powder surface areas and porosities are calculated. The peculiarities of the adsorption  isotherms of the investigated samples are analyzed before and after interaction with water in terms of their correspondence to a  certain type according to the recommendation of the International  Union for Pure and Applied Chemistry (IUPAC), as well as to a  certain porosity type, which is necessary for the understanding of  their further application. The mechanism of aluminum nitride powder and water interaction is discussed. It is shown that aluminum nitride interacts with water by the ion-adsorption mechanism that  leads to the formation of porous agglomerates consisting of needle and platelet shaped aluminum oxyhydroxide nanoplates  connected by contacts with pores 55 Å in diameter. Specific surface  area increases from 48 to 115 m2/g. It is also found that phase  composition changes as a result of AlN nanopowder interaction with aqueous environment, and interaction products are represented by AlO(OH) and Al(OH)3 phases.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>адсорбция</kwd><kwd>ультрадисперсные порошки</kwd><kwd>поры</kwd><kwd>удельная поверхность</kwd><kwd>ионность связи</kwd><kwd>ионно-адсорбционный механизм</kwd><kwd>нитрид алюминия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>adsorption</kwd><kwd>ultradispersed powders</kwd><kwd>pores</kwd><kwd>specific surface</kwd><kwd>bond ionicity</kwd><kwd>ion-adsorption mechanism</kwd><kwd>aluminum nitride</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Самсонов Г.В.
