The Continuous Drying of Refractory Concrete
The aim of this paper is to help avoid a steam explosion during drying. Drying refractory occurs via the evaporation of water on the heated side and its drain on the cold side.

Morphology Evolution of the Hydration Products of Hydratable Aluminas at 40 °C
Hydratable Alumina (HA) is an important CaO-free hydration binder for no-cement castables. Different sources of hydratable alumina have varied phase compositions and physical properties (such as specific surface area and particle size), which could generate hydration products with different phases and structures during hydration.
Improved Precision Casting of Titanium Alloys Using Calcium Zirconate Moulds
The main challenges of titanium investment casting are the high melting temperature and the extreme reactivity of the melt. Therefore, a new ceramic material for crucibles and moulds based on calcium zirconate (CaZrO3) is under development.
Marcheluzzo Ceramics Supplies New Dryer for Refractories Production
Marcheluzzo Ceramics, located in Caldogno, Vicenza/IT, develops and supplies plants for drying and environment control in the production of sanitaryware,
ceramic insulators, refractories and heavy clay ceramics. Marcheluzzo Ceramics has recently started up a dryer supplied to Eco Inter S.r.l., a well-known Italian producer of refractories for the ceramic and food industries. The company is located in the Novara Province, in an area where ceramic tradition reached highest levels of quality and technology for tableware, sanitaryware and refractory production in the past.
Improvements in Drying Behaviour and Explosion Resistance of Microsilica-Gel Bonded No-Cement Castables
Microsilica-gel bonded no-cement refractory castables (NCCs) have drawn lots of interest lately, because of their easier handling, storage and transportation compared to silica-sol NCCs.
Manufacture of Refractory Multilayer Composites with Optimised Thermal and Chemical Properties Via the Tape Casting Process
Multilayer refractory structures have been manufactured by means of cast green tapes to improve their thermal and corrosive properties.
Functionally Graded Materials Made by Water-Based Multilayer Technology
The development of Functionally Graded Materials (FGM) with graded microstructures concerning composition or porosity opens new fields of application.
