(15) A glass substrate dipped in a mixture of methyltrimethoxysilane (MTMS), ammonium hydroxide, and a large amount of methanol can realize superhydrophobicity, but a post-synthesis modification is needed, by which methyl groups were introduced using a solution of methyltrichlorosilane
or hexamethyldisilazane in hexane.
The project will produce fumed silica using Cabot's world-class manufacturing technology and utilizing the methyltrichlorosilane
byproduct from Bluestar's silicones monomer production.
The 90 to 110 [micro]m thick silicon carbide shell (density 3.15 to 3.5 g/[cm.sup.3]) was made in 16 hours at 1500[degrees]C in argon with additional hydrogen gas (250 to 400 L/h), saturated at 25[degrees]C with 4% methyltrichlorosilane
that decomposes into SiC and HCl.
