Porcelain harder than steel
WebA diamond is much harder than corundum, even though they're only one division apart on the scale. The Mohs scale starts approximately linear, but the curve climbs sharply at the high end. Corundum (9) is twice as hard as topaz (8), and diamond (10) is four times as hard as corundum. (Note: diamonds, and only diamonds, can scratch other diamonds). WebSpecific gravity. This chart displays specific gravity of materials, which is the density of a material relative to the density of water. Compared to metals, ceramics tend to have less than half of the density. Furthermore, tungsten is heavier than lead and around the same weight as gold, making it an unusually dense material.
