Effects of Metallic Additions on Fired Ceramic Materials
This paper describes the effect of metal powder addition to a standard fired ceramic kiln-furniture product. Different amounts and combinations of aluminium and silicon are tested. Small additions have the metals completely oxidised forming secondary mullite or corundum.
Alteo Announces Price Increase
Throughout 2018, alumina production has kept suffering from significant continuous cost increases – in particular bauxite, energy, freight and caustic soda.
Virtual Material and Process Development – Save Time and Reduce Risks by Computer Simulation
Prototype manufacturing and testing is time-consuming and costly. To save time and to reduce cost, use of computer simuation is state-of-the-art in many industries, e.g. for product development or process optimisation. Nevertheless, simulation requires some invest in software, skilled people, and time for model development and validation. For this reason, Small and Medium-Sized Enterprises (SMEs) often hesitate to make use of simulations for their R&D activities or technical services. To overcome this hurdle, VM&P Virtual Materials and Processes GmbH/DE offers its simulation expertise as service particularly for SMEs.
Re-engineered Calcium Aluminate Cement for Refractory Castables
The effect of Calcium Aluminate Cement (CAC) fineness and mineralogy on workability and high temperature performance of two commercial available CAC was investigated.
Advanced Anorthite Lightweight Castables for Carbon-Containing Atmosphere Application
Heat insulating refractories have been widely adopted owing to the low thermal conductivity that permit reducing heat losses through the lining of furnaces, to reduce a consumption of energy carriers in thermal units.
Engineering the Microstructural Parameters of Erosion Resistant High Alumina Castables
Different parameters (i.e., particle size distribution and packing, size and amount of coarse grains, and other features of the resulting microstructure) can affect the erosion resistance of refractory castables.
