In this work, the effect of mechanochemical activation time of mixtures of initial components on the sintering of magnesium titanate ceramics is studied. The apparent activation energy of sintering samples ...
... spinel occurs in the range of 800…1050 ? from synthesized xerogels based on different ratios of magnesium and aluminum chlorides and nitrates. It was found that the crystalline structure of the spinel ...
Yttrium aluminum garnet (YAG) powders were synthesized via chemical precipitation, both with and without the addition of ammonium sulfate as a dispersant. The impact of the dispersant on the particle size ...
The temperature regimes of the thermal extraction method for obtaining silicon dioxide from rice husk and various conditions of subsequent milling were investigated. Elemental, X-ray phase, petrographic ...
A dense-sintered protoenstatite ceramics based on fluorinated talc was obtained. Influence of BaO and Al2O3 additives on the sinterability, structure and strength of ceramics was investigated. It makes ...
The results of the initial stages of work on assessing the possibility of obtaining whiskers of titanium nitride from the gas phase are presented. A theoretical assessment was made of the possibility of ...
The features of the action of cationic promoters on the thermochemical behavior of zirconium hydroxide have been investigated. It is shown that the composition and properties of the obtained materials ...
It has been established by X-ray diffraction and electron microscopy that in glasses of the La 2 O 3 - B 2 O 3 - GeO 2 a film texture of lanthanum germanate La 2 Ge 2 O < sub> 7 with a thickness ...
The proposed method was used to determine the values ??of the viscosity of glass and glass-crystalline compositions in the temperature range of foaming. It was found that when the glass-crystalline composition ...
