It is known that the introduction of small Na2O additives (up to 5 mol. %) into the glass composition of the ZnO–MgO–Al2O3–SiO2 (ZMAS) does not interfere with the production of zinc spinel (ZnAl2O4) based ...
The processes of thermochemical hardening of aluminosilicate glass are investigated. The glass was processed in a KNO3 melt under industrial and laboratory conditions at 440…480 °C for 1…120 h. The effect ...
Zinc magnesium aluminosilicate (ZMAS) glasses have been obtained with the addition of Na2O (from 1.1 to 7.0 mol. %). Influence of the Na2O content on glass forming ability and effectiveness of the ion-exchange ...
For the first time, a local Abrio method for estimating birefringence was applied to hardened glasses, and the distribution of microstresses in float glass subjected to ion exchange hardening was studied. ...
The paper presents the results of a study on the cyclic strength of cutting ceramics: a replaceable polyhedral plate developed at NSTU and VOK-60 cutting ceramics when processing a hardened steel billet ...
The paper presents the results of a study on the durability of cutting ceramics: a replaceable polyhedral plate developed at NSTU and cutting ceramics WOK-60 when processing hardened steel blanks made ...
The preparation and mechanical properties of composites 20 & # 37; molar fraction of Al 2 O 3 and 80 & # 37; [3Yb & # 8211; TZP] modified with strontium oxide. It is shown that in the process of heat ...
The influence of the mass content of Al 2 O 3 on the stability of the phase composition and the strength of the ceramics of the Al 2 O 3 -3Y system has been determined. -ZrO 2 prepared according ...
Glasses of silicate, borosilicate, aluminosilicate and aluminoborosilicate systems are considered. Expressions have been obtained for determining the activation energy of hydrogen permeability, the hydrogen ...
