Mechanical properties of commercial high strength ceramic core materials.
OBJECTIVE The objective of the present study is to evaluate and compare the flexural strength, dynamic elastic moduli and true hardness (H(o)) values of commercial Vita In-Ceram alumina core and Vita In-Ceram matrix glass with the standard aluminous porcelain (Hi-Ceram and Vitadur), Vitadur N and Dicor glass and glass-ceramic. METHODS The flexural strength was evaluated (n=5) using 3-point lo...
متن کاملHIGH TEMPERATURE ELASTIC PROPERTIES OF REFRACTORY MATERIALS
Abstract: A pulse-echo technique, based on ultrasonic "long-bar" mode (LBM) velocity measurements, working up to 1700°C is described. Magnetostrictive transducers and ultrasonic lines used in a 40-85 kHz frequency range are detailed. The conditions of choice of fundamental parameters (frequency, line geometry, sample size) are discussed in relation with the nature and the microstructure of ...
متن کاملTHERMO-MECHANICAL DESIGN OPTIMIZATION OF CORDIERITE–MULLITE BASED KILN FURNITURE
Abstract: Cordierite-Mullite based kiln furnitures are widely used in fast-firing of ceramic products because of their low thermal expansion which confer them a very good ability to thermal shock resistance. Difference in CTE of constituent phase can develop damage during thermal cycling due to internal stresses. Increase in industrial competitiveness leads to the development of new means for e...
متن کاملImproving the mechanical and bioactivity of hydroxyapatite porous scaffold ceramic with diopside/forstrite ceramic coating
Objective(s): Scaffolds are considered as biological substitutes in bone defects which improve and accelerate the healing process of surrounding tissue. In recent years a major challenge in biomaterials is to produce porous materials with properties similar to bone tissue. In this study, the natural bioactive hydroxyapatite scaffolds with nano Diopside /Forstrite coating was successfully synthe...
متن کاملMicro Structural Investigations and Mechanical Properties of Macro Porous Ceramic Materials from Capillary Suspensions
Recently, we have introduced a novel, material-independent processing method for producing macro porous ceramics with capillary suspensions as a stable precursor. A capillary suspension is a three-phase system where a small amount of an immiscible secondary liquid is added to a suspension resulting in the formation of a sample spanning particle network. This technology provides open porosities ...
