Установлено, что при замещении 4 % MgO на ZnO синтезированный при температуре 1 150 °С керамический материал характеризовался более высокими значениями кажущейся плотности (не менее 1 835 кг/м3), механической прочности при сжатии (300 МПа) и термостойкости (более 80 термоциклов), а также низким значением температурного коэффициента линейного расширения (ТКЛР) (–0,25 · 10–6 К–1), что обусловлено формированием кристаллических фаз сподумена, шпинели, форстерита, корунда, ганита и кварца.</p></abstract><trans-abstract xml:lang="en"><p>The results of a study the influence of magnesium oxide substitution with zinc oxide in the Li2O–MgO– Al2O3–SiO2 system, as well as the introduction of pre-synthesized ganite ZnAl2O4, on sintering, phase formation and thermal expansion of synthesized materials are presented. It was found that after substitution of 4 % magnesium oxide MgO with zinc oxide ZnO, the ceramic material synthesized at a temperature of 1 150 °C was characterized by higher values of apparent density (not less than 1 835 kg/m3), mechanical compressive strength (300 MPa), and heat resistance (more than 80 thermal cycles), as well as low values of LTEC (–0,25 ∙ 10–6 K–1), which is due to the formation of crystalline phases of spodumene, spinel, forsterite, corundum, ganite and quartz.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>термостойкая керамика</kwd><kwd>система Li2O–MgO–Al2O3–SiO2</kwd><kwd>оксид цинка</kwd><kwd>ганит</kwd><kwd>синтез</kwd><kwd>фазовый состав</kwd><kwd>температурный коэффициент линейного расширения</kwd><kwd>термостойкость</kwd><kwd>механическая прочность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>heat-resistant ceramics</kwd><kwd>Li2O–MgO–Al2O3–SiO2 system</kwd><kwd>zinc oxide</kwd><kwd>ganite</kwd><kwd>synthesis</kwd><kwd>phase composition</kwd><kwd>linear thermal expansion coefficient</kwd><kwd>heat resistance</kwd><kwd>mechanical strength</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">Cordierite obtained from compositions containing kaolin waste, talc and magnesium oxide / E.
