Porous Ceramic Foam -- Taking The Heat Out Of Furnaces
A new porous ceramic material, called Hi-Por, could be set to replace the refractory ceramic fibres (RCFs) used as an insulation material in research and industrial furnaces following the European Union's (EU) classification of RCFs as Category II carcinogens. Hi-Por is made using ceramic powders and foaming agents to produce a material that can withstand changes in temperature from ambient to 1600 degrees Celsius in less than fifteen minutes.
Scientists Use Fossilized Emu Eggshells To Discern Changes In Vegetation, Provide Additional Evidence Of Human Impact On Australian Landscape
