19/3/2010· I''ve made graphite crucibles, though no resins, only refractory clay and graphite. And yes, glazing improves them, ground glass, fire clay and a little Borax. They are the reason I bought a ceramics kiln. I like my Silicon Carbide crucibles best but they are expensive
List of refractive indices. Many materials have a well-characterized refractive index, but these indexes often depend strongly upon the frequency of light, causing optical dispersion. Standard refractive index measurements are taken at the "yellow doublet" sodium D line, with a wavelength of 589 nanometers . There are also weaker dependencies

Silicon carbide is composed of tetrahedra of carbon and silicon atoms with strong bonds in the crystal lattice. This produces a very hard and strong material. Silicon carbide is not attacked by any acids or alkalis or molten salts up to 800°C. In air, SiC forms a protective silicon oxide coating at 1200°C and is able to be used up to 1600°C.
3/12/2010· Gosh, impressive, and easy as pie. Watch the video below to see just how easy it all is. The Sahara Solar Breeder Project is a joint initiative by universities in Japan and Algeria that aims to build enough solar power stations by 2050 to supply 50 per cent of the energy used by humanity. The idea is to begin by building a small nuer of
