Castability of a Commercial Castable Glass Ceramics.

Dental Materials Journal, 1998
This study was carried out to determine the design and thickness of the cervical margin of a castable ceramic restoration from the point of view of its castability. Castability of castable ceramics was lower compared to Ag-Pd-Au and Co-Cr alloy with the use of the mesh pattern and rod pattern test (p < 0.05).

Investigation of the milling route for the development of colloidal suspensions to be used as binder in refractory castables

Open Ceramics, 2023
Refractories castables bonded with CAC (calcium aluminate cement) have a limitation when they are used at high temperature in micro-silica containing system and/or in acidic corrosive environments.

Simultaneous enhance of the thermal shock resistance and slag-penetration resistance for tundish flow-control refractories: The role of microporous magnesia

Materials & Design, 2023
As the low thermal shock and slag-penetration resistance of the magnesia castables cause the premature failure of tundish flow-control devices leading to the pollution of steel, the microporous magnesia with high closed porosity and intergranular CaZrO3 ...

Effect of B2O3 on Volume Stability and Strength of Corundum-based Castables

High Temperature Materials and Processes, 2017
Calcium aluminate cements (CAC) with 0.21 wt% B2O3 and without B2O3 were used as binders of corundum-based castables. The properties of the castables with and without B2O3 after heat treatment at 110 °C, 1,100 °C and 1,450 °C were investigated, with ...

Impacto do uso de fibras poliméricas no desempenho de concretos refratários aplicados por projeção Influence of the polymeric fibers on shotcrete refractory castables

Cerâmica, 2004
A utilização de fibras poliméricas em concretos refratários tem sido motivada principalmente pela possibilidade de se elevar a velocidade de secagem sem acentuar o risco de explosão destes materiais. As fibras quando empregadas em concretos aplicados por

Corrosion mechanisms of Al2O3-SiC-C refractory castables by iron and slag based on post-mortem analysis of industrial samples

Open Ceramics, 2023
The Al2O3-SiC-C or ASC castables are used in the main runners of blast furnaces. Most of the papers published to date focus on laboratory corrosion tests because access to the post-mortem samples of ASC castables is difficult.

Thermal characteristics of Al2O3-MgO and Al2O3-spinel castables for steel ladles [PDF]

, 2011
[[abstract]]The hot properties of the Al2O3-MgO castables containing 5.5 wt.% MgO and 1.36 wt.% CaO with and without the addition of 0.75 wt.% microsilica and the Al2O3-spinel castables containing 20 wt.% Al2O3-rich spinel of 90 wt.% Al2O3 and 1.70 wt ...
