Abstract

A refractory composition comprises a major amount individually of dead burnt magnesite, added alumina 10-35 per cent. by weight, remainder, but with a minimum of 20 per cent. chrome ore. Preferred proportions of magnesite are 45-70 per cent. and of chrome ore 20-40 per cent. Part of both alumina and magnesite is finely divided. Magnesite is defined as material giving magnesia at high temperatures and includes magnesite rock and magnesium hydroxide. Chrome ore. containing up to 26 per cent. iron oxide and magnesite containing up to 5 per cent. lime may be used. Lignin waste liquor magnesium sulphate, resins, bitumen or oxychloride cements may be used as temporary bonds and ball clay added to aid pressing. Sodium silicate may be included as an additional bond. Magnesium silicates may also be present, and also mineralizers, e.g. fluorides, borates or phosphates.
