Sulfur also is harmful to the iron. It gives socrack formation in the red-hot state. The ores are roasted before processing. Roasting is heating with full air admission so that the sulfur in the ore is oxidized to sulfur dioxide, which disappears. The risk of red brittleness in the iron is decreased or ehminated. 

Zinc is a bluish-white, lustrous metal. It is brittle at ordinary temperatures but malleable at 100 to ISOoC. It is a fair conductor of electricity, and burns in air at high red heat with evolution of white clouds of the oxide. 

Titanium is a white metal and, when cold, is brittle and may be powdered. At a red heat it may be forged and drawn. The tensile strength of titanium is almost the same as that of steel, while its specific gravity (4.5) is almost two times less than that of steel. Hence, its specific strength (tensile strength/speciflc gravity) is 1000, which is considerably higher than that of 18/8 steel, which has a value of 700. Titanium is now available as plate, sheet and tube, and its use in chemical plant construction is considered common. 

Semimetal that occurs as a tin-type, brittle form and as a yellow, unstable, nonmetallic form. Its main use is in alloys to harden other metals. Without the addition of antimony, lead would have remained the "softy" of the Periodic Table. But with antimony, lead ruled the print world and later found use in the production of rechargeable batteries. It can be found in older ceramic glazing (yellow orange). Everyday encounters antimony sulfide in match heads and red rubber, antimony oxide is used as a flame retardant. Pure antimony is starting to become of interest in the electronics sector. 

Malononitrile can be distilled in small amounts (50 cc. or so) at ordinary pressure the boiling point is around 220°. However, the longer heating necessary with larger amounts is apt to cause violent decomposition. In such a case the liquid darkens, boils spontaneously, and finally spurts from the flask in a cloud of white fumes and burning liquid the latter partially solidifies to a brittle red solid. 

Steel It has a higher C content (usually 0.5-1%) and is harder than soft bon. An important property of steel is that it may be hardened. If heated to bright redness (to obtain an austenitic alloy) and suddenly cooled quenched), by putting it in water, oil, etc, it becomes hard and brittle due to the formation of the very hard martensite. Brittleness can be removed by tempering (that is by a carefully heating for a short time at, say, 250-300°C) to release or dimmish the internal strains resulted from quenching. 

Exploration for unconformity-related deposits is based firstly on Proterozoic red-bed basins overlying basement complexes and source regions characterized by high U contents. Given this criteria alone, there are nearly 200 basins that would qualify. Graphitic metasedimentary units within the basement complex are desirable, but not necessary, as exemplified by the Nabarlek deposit in the Northern Territory, Australia (Polite et al. 2004). Repeated brittle reactivations of ductile structures, normally from far field tectonic events, that may offset the basal unconformity and were foci for fluid flow are required.
