“…Now theoretical ideas about glass formation and physical parameters of low-melting glasses including TCLE are very limited [19][20][21][22][23][24][25]. Also interest in this class of glasses due to their prospective application is very high [18].…”

A second-order regression polynomial model is offered, taking into account a pair components interaction for TCLE calculation of low-melting glasses in system MgSO4-KPO3-Na2B4O7. The analysis of the obtained model is carried out. The results adequacy, obtained by modeling in comparison with the experimental data, is shown. It is established that the square pair interaction of the MgSO4-KPO3 and MgSO4-Na2B4O7 components, when modeling this system, can be neglected.

“…Other than low melting temperature, adjustable degradation rate is another peculiarity of PG . The PG is based on [PO 4 ] groups with a polymer‐like, regular tetrahedral structure . The physical structure of PG is interrupted by network modifiers such as CaO, Na 2 O, and MgO.…”

The coral, whose main composition is aragonite-type calcium carbonate, has been widely used as bone substitute in clinic. However, the study on calcium carbonate bioceramic has not been largely reported due to difficulty in sintering calcium carbonate which is liable to evidently decompose at low temperature. In this study, a novel calcium carbonate composite ceramic was fabricated by sintering fast at a low temperature. A degradable, biocompatible phosphate-based glass (PG) which grew liquid at a low temperature was added as sintering agent in the sintering process. The sintering schedule was explored by thermal analysis. The phase composition, microstructure, compressive strength, and biocompatibility of calcium carbonate composite ceramics were evaluated. The results revealed that the optimum holding time at the sintering temperature was 20 min. The obtained calcium carbonate composite ceramics did not produce calcium oxide but new compounds according to phase analysis. The compressive strength of calcium carbonate composite ceramics correspondingly increased with growing addition of PG ranging from 10 to 50 wt%. The cell proliferation on the calcium carbonate composite ceramic was not compromised but augmented compared to the neat calcium carbonate ceramic without adding PG as sintering agent. The novel calcium carbonate composite ceramic is a promising bone substitute for bone defects. H.-E. Kim-contributing editor Manuscript No. 35122.

“…Low-melting glasses include whole groups of inorganic glasses of various systems having a softening point below 550-600 °C [3][4][5][6][7][8][9][10][11][12][13]. The relative low softening temperature of such glasses makes it possible, for example, to carry out a vacuum-tight junction under conditions that do not damage the units to be joined in the soldering zone [1][2][3][4][5][6][7][19][20]. At the same time, the creation of a strong connection of units requires that the glass connecting them spreads well and moistens the units surfaces.…”

“…The creation of a universal solution is not possible because of the wide range of products to be connected and there are the various requirements for their connection. To date, the experimental data for low-melting glasses has been obtained in numerous glass-forming systems [14][15][16][17][18][19][20][21][22][23][24][25] and there is a constant search of new compositions.…”
