“…According to the literature data, the main crystal phase formed during the devitrification of pure Bioglass 45S5 glasses has not been established precisely. Some authors indicated the formation of the Na 2 Ca 2 Si 3 O 9 phase [58][59][60]; others pointed at the Na 6 Ca 3 Si 6 O 18 phase formation [44,46]; and there are works in which Na 4 Ca 4 Si 6 O 18 was determined as the crystalline phase after glass devitrification [23,61]. The current uncertainty can be explained by the close lattice parameters of all three compounds, Na 2 Ca 2 Si 3 O 9 (hexagonal, P31 (152), a = 10.464, c = 13.176) [62], Na 4 Ca 4 Si 6 O 18 (hexagonal, P32 (152), a = 10.464, c = 13.168) [63], and Na 6 Ca 3 Si 6 O 18 (rhombohedral, R-3m (166), a = 10.500, c = 13.184) [64], as well as by the isostructurality of the Na 6 Ca 3 Si 6 O 18 and Na 4 Ca 4 Si 6 O 18 phases and the high-temperature form Na 2 Ca 2 Si 3 O 9 .…”

“…However, this system is not limited to the variety of glasses and glass-ceramics derived from the 45S5 bioglass concept. The system is sufficiently extensive to open the possibility of obtaining composite materials based on bioglass and calcium phosphate materials [20,21]; ceramics from powders produced by mixed-anion synthesis [22]; and ceramic materials using intermediate phases, which can be converted into final compounds during heat treatment [23]. This review aims to consider approaches to obtaining such materials and their properties.…”

Calcium phosphate materials and materials based on silicon dioxide have been actively studied for more than 50 years due to their high biocompatibility and bioactivity. Hydroxyapatite and tricalcium phosphate are the most known among calcium phosphate materials, and Bioglass 45S5 is the most known material in the Na2O–CaO–SiO2–P2O5 system. Each of these materials has its application limits; however, some of them can be eliminated by obtaining composites based on calcium phosphate and bioglass. In this article, we provide an overview of the role of silicon and its compounds, including Bioglass 45S5, consider calcium phosphate materials, talk about the limits of each material, demonstrate the potential of the composites based on them, and show the other ways of obtaining composite ceramics in the Na2O–CaO–SiO2–P2O5 system.

“…Bioresorbable materials are in demand in modern medicine for creation matrices that promote and support bone regeneration, thus eliminating the "gold standard" of using bone material taken from the human body [1,2]. Materials based on calcium phosphates with a molar ratio of 0.5 < Ca/P < 1.67, calcium carbonates [3] and calcium sulfates [4] have the ability to resorb when used in regenerative methods of bone defect treatment [5][6][7][8][9]. Different composite materials containing calcium sulfates and other components such as calcium phosphates [10][11][12][13][14] or calcium citrate tetrahydrate [15] in the phase composition are now under investigation.…”

Materials (cement stone samples) in the CaO-K2O-SO3-H2O system with the target phase compositions, including syngenite K2Ca(SO4)2·H2O and calcium sulfate dihydrate CaSO4·2H2O, were prepared from powder mixtures of calcium sulfate anhydrite CaSO4, and/or calciolangbeinite K2Ca2(SO4)3, and potassium sulfate K2SO4 via hydration reactions at a water/powder ratio within an interval of 0.5–0.9. It was revealed that samples with contents of 25, 50, 75 and 100 mol% of syngenite K2Ca(SO4)2·H2O demonstrated a nonlinear dependence of their respective microstructures on their phase compositions. The microstructures of samples with phase compositions of 25 and 75 mol% of syngenite K2Ca(SO4)2·H2O consisted of pillar crystals. The microstructures of samples with phase compositions of 50 and 100 mol% of syngenite K2Ca(SO4)2·H2O consisted of plate crystals. An explanation of microstructure formation was set forth, taking into account equilibria of the dissolution–crystallization processes during cement stone formation. Materials obtained in the CaO-K2O-SO3-H2O system consisting of biocompatible and resorbable (soluble in water) phases can be recommended for testing as potential substances for bone defect treatments.

“…Alternatively, sodium rhenanite CaNaPO 4 can be obtained by cement technology with subsequent firing. The work [23] shows a method for obtaining CaNaPO 4 from brushite cement, prepared by the reaction of β-tricalcium phosphate, monocalcium phosphate monohydrate (Equation ( 3)), and a highly alkaline bioactive glass (composition (wt.%): SiO 2 -50, Na 2 O-25, CaO-20, P 2 O 5 -5).…”

Ceramics Based on Sodium Rhenanite CaNaPO4, Obtained via Firing of Composite Cement-Salt Stone

et al. 2022

View full text Add to dashboard Cite

Ceramics based on rhenanite CaNaPO4 with density of 0.94 g/cm3 and compressive strength of 10.3 MPa was obtained via firing at 900 °C of composite cement-salt stone prepared from a hardening powder mixture of calcium citrate tetrahydrate Ca3(C6H5O7)2∙4H2O and sodium dihydrogen phosphate NaH2PO4. The phase composition of the obtained samples of cement–salt stone was represented by monetite CaHPO4, unreacted sodium dihydrogen phosphate and calcium citrate tetrahydrate. According to the XRD data, the phase composition of the ceramic samples after annealing in the temperature range of 500–700 °C was mainly represented by the β-CaNaPO4 phase. It was found that after an annealing at temperature of 900 °C, the phase composition of ceramics was presented with the only phase of β-CaNaPO4. It was demonstrated that an increase in the annealing temperature led to an increase in the grain size from 1 μm after annealing at 500 °C to 5 μm after annealing at 900 °C. Obtained ceramic material based on CaNaPO4 could be important for regenerative treatments of bone tissue defects.
