1·Chromium Oxide Specific gravity 5.2, Moh hardness 2.5 Enhances friction, but not popular because of high price in most parts of the world.
氧化铬5.2比重2.5莫氏硬度,增强摩擦力,因为高价格因而在世界的大多数地方不流行的。
2·Granted the weight and the specific gravity of a body, we can calculate its volume.
假设已知一个物体的重量和比重,我们就能算出它的体积。
3·Aluminum Oxide Specific gravity 2.4 Moh hardness 3. More a filler than an abrasive. Tends to fade, but has good wear resistance. Will polish the opposing surface.
氢氧化铝比重2.4莫氏硬度3。比磨料加得更多的填充物。有衰退趋势,但耐磨性好。将抛光对偶。
4·Crystal habit, luster, color, streak, cleavage, fracture, fluorescence, phosphorescence, specific gravity and magnetism.
