Abstract—

Calcium alkali metal (potassium and sodium) double and triple phosphates have been synthesized in different ways. Was for the first time used reaction sintering to produce ceramics based on calcium alkali metal mixed phosphates and investigated the densification behavior of mixed phosphate-based multiphase materials during sintering by this method. Was presented the microstructure of polished surfaces of sintered samples differing in phase composition and determined the density of ceramics prepared using reaction mixtures differing in composition. The effect of reaction sintering on the porosity of the ceramics has been assessed. Using stereolithographic printing and reaction sintering, was produced macroporous mixed calcium phosphate-based ceramic implants. Their compressive strength has been determined to be 0.78 ± 0.21 MPa for two-phase samples and 1.02 ± 0.13 MPa for three-phase samples.

基于磷酸钙的高强度大孔陶瓷制备中反应烧结的潜力

摘要-

钙碱金属（钾和钠）双磷酸盐和三磷酸盐的合成方法不同。首次使用反应烧结法生产基于碱金属钙混合磷酸盐的陶瓷，并通过这种方法研究了混合磷酸盐基多相材料在烧结过程中的致密化行为。介绍了相组成不同的烧结样品抛光表面的微观结构，并确定了使用组成不同的反应混合物制备的陶瓷的密度。已经评估了反应烧结对陶瓷孔隙率的影响。使用立体平版印刷和反应烧结，制备了大孔混合磷酸钙基陶瓷植入物。它们的抗压强度已确定为0.78±0。
