wikipedia: The silica firebricks that line metallic-making furnaces are used at temperatures as a lot as 1650°C (3000°F), which could melt many different kinds of ceramic, and really component to the silica firebrick liquefies. HRSI, a fabrics with a similar composition, is used to make the insulating tiles of the area vacation. yet they have low thermal conductivity, as maximum ceramics do. for metals, there are plenty that melt at severe temperatures, yet they don't seem to be low-cost. Platinum melts at 1772ºC , case in point. Titanium melts at 1668ºC (a 2d reference says 1725ºC) so it might want to be the perfect determination. .

Order is:
1. Silver (Ag)
2. Copper (Cu)
3. Aluminium (Al)
Poorest conductors of heat are lead (Pb) and mercury (Hg).
And i have a test on metals tomorrow.....
