Boron or boron is a dark powder. In fact, the existence of drill is a mystery, because it has a star shape and there seems to be no way in which it originated.
It does not occur independently in nature, but "hides" in numerous compounds with other substances.
Boron is an essential element for all plants, as it is a component of the cell walls. That is why it is added to fertilizer. In addition, boron connections have many industrial applications.
Drill: hard as diamond, soft as silk
Boron nitride is almost as hard and shiny as a diamond. A coarse variant is used as an abrasive in the industry, and a fine version is added to powders to make them shiny and silky soft.
Another boron joint, triethyl boron, is a highly flammable substance that ignited the engines of the Saturn V rockets from NASA.
