PSC is currently practiced in table-ware industries however, application to the technical ceramics is limited owing to the collapse of cast part while de-moulding during pressure cast cycle under pneumatic pressure. Current study focuses on this key issue and demonstrated pressure casting process successfully for the fabrication of alumina parts. Slips of a mixture of alumina with different particle sizes in the various proportions and solid loadings were prepared. Slip under PSC resulted in effective interlocking of the particles retaining the shape while de-moulding and achieved a sintered density of 98.6% of theoretical density (TD). Slurry on CSC exhibited a lower sintered density of 97% of TD. Selection of particles with sizes in optimised proportion for PSC results in effective interlocking of particles in green parts as well as grains on sintering as revealed by the microstructure. This leads to higher density and mechanical properties. Slip thus optimised were shaped into solid spheres of ϕ 60 mm by PSC targeting grinding applications.","PeriodicalId":7224,"journal":{"name":"Advances in Applied Ceramics","volume":"1 1","pages":"211 - 221"},"PeriodicalIF":2.2,"publicationDate":"2021-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84085849","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the current study, bar-shaped hydroxyapatite (HA) specimens were hung between two Pt wire electrodes and consolidated by FS through a direct electric field at a constant furnace temperature (1000°C or 1100°C) in air. The electric field facilitated the sintering of HA at relatively lower furnace temperatures than that obtained using the conventional sintering method. The voltage required for the onset of the flash decreased with increasing furnace temperature. The effects of the DC electric field strength at different sintering furnace temperatures were examined in terms of the phase evolution and stability of HA. HA phase dissociation was not observed regardless of the electric field strength or furnace temperature because of the very short FS time. Higher grain growth with fast densification in the flashed-sintered HA samples occurred with increasing electric field strength at each furnace temperature.","PeriodicalId":7224,"journal":{"name":"Advances in Applied Ceramics","volume":"17 1","pages":"300 - 306"},"PeriodicalIF":2.2,"publicationDate":"2021-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84777154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

VSM presented soft ferromagnetic behaviour. From in vivo evaluations, changes in serum levels are analysed at different days of study after administration of bare and coated NPs through the intraperitoneal route of administration in albino rats. Toxicity parameters revealed a transient increase at day 1 but a gradual decrease thereafter. For biodegradation studies, NPs exposure in lysosomal-like medium showed insignificant changes in the absorbance spectrum for a short interval of time, however, dynamical degradation effects were observed on Day 8. Apoferritin studies disclose the growth of absorbance near 260 nm, which reveals progressive and partially filled proteins with iron ions.

However, the occlusal screw access hole interrupts porcelain integrity, which may result in porcelain cracks or fractures. There is insufficient scientific evidence to prove that screw access holes affect the fracture load of implant-supported monolithic zirconia crowns. In this study, we investigated the effects of the screw access hole and its preparation technique on the fracture load of implant-supported monolithic zirconia single crown. The crowns were designed for the maxillary right first premolar. Three techniques analysed for screw access hole preparations included computer-aided designed/computer-aided manufactured (CAD/CAM) before sintering, manually prepared after sintering, and then resintering. Our findings show that the screw access holes and preparation techniques have no significant effects on the fracture load of implant-supported monolithic zirconia single crown. On the other hand, the screw access hole preparation techniques affect failure initiation in implant-supported monolithic zirconia single crown.","PeriodicalId":7224,"journal":{"name":"Advances in Applied Ceramics","volume":"43 1","pages":"1 - 11"},"PeriodicalIF":2.2,"publicationDate":"2021-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78550512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This has innovated the introduction of reinforcement in traditional materials such that the resulting composite material would be an advantage for the collaborating influence of the combined matrix and the reinforcement. Single-phase ceramics have been limited in application due to low densification and poor properties. Hence, ceramic matrix composite is the family of materials that have undertaken quick innovation in past years because of its auspicious properties for structural and functional usage. This concept has made the incorporation of sintering additives into the monolithic form of ZrO2 of high importance because of the poor densification and fracture toughness of undoped ZrO2. The addition of sintering additives provides good functionality to the improvement of ceramic materials. This paper painstakingly reviews the effects of diverse sintering additives such as carbides, borides, nitrides on the microstructure, densification, and mechanical properties of ZrO2 ceramic matrix using different sintering techniques and it lastly stated a futuristic approach to the enhancement and characterisation needed for ZrO2 ceramic matrix composites.","PeriodicalId":7224,"journal":{"name":"Advances in Applied Ceramics","volume":"47 1","pages":"319 - 335"},"PeriodicalIF":2.2,"publicationDate":"2021-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74784817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
