Steelites. Cheddite type expls patented in 1902 in Ger by E. Steele and manufd in Engl by Steelite Explosives Ltd. They contained K chlorate 72.5 to 75.5, oxidized rosin 23.5 to 26.5 and castor oil 0,5 to 1.5%. See refs under Chlorate Explosives in Vol 2, C206-R.

Colophony —Starch Nitrated Mixture (called by Davis Oxidized Rosin and by its inventor E, Steele Residee). It is a solid prepd by treating an intimate mixture of finely pulverized colophony 90 Sc starch 10% with cold 42 Be nitric acid. A homogeneous solid, tormed after several mins, was used as an ingredient in the prepn of potassium chlorate expls, known as Steelites. For their prepn, finely pulverized and dried K chlorate residee, in desired propns, were slightly moistened...

There has been some renewed interest in the use of tin-zinc alloy electroplate as a substitute for cadmium coatings on steelIt has been pointed out that tin-zinc coatings produce less loose corrosion product than zinc during full outdoor exposure ... 

Steatite. Massive form of the mineral talc, Mg3Si40io(OH)2. The chief sources are in USA, France, Italy, India, Austria and Norway. The natural rock can be machined and the shaped parts fired for use as electroceramics. A far greater proportion is ground and shaped in the usual way with a clay bond to produce low-loss electroceramics thermal expansion (20-500°C) 7-9 x 1(H volume resistivity (300°C) 10 - 10 ohm-cm. dielectric constant (1 MHz) S.5-6.5 power factor (IMHz) 5 - 25 x ICH. Steatite is also used as a raw material for cordierite electroceramics and for refractories containing cordierite. Steelite. A high strength hotelware body, presumed to contain alumina, first introduced by Ridgeway Potteries, 1967. Now the name of a hotelware company, Steelite International Ltd, Stoke-on-Trent.
