Facts About Boron Boron is a multipurpose element. It's a crucial nutrient for plants, an important component in the nuclear industry and the main ingredient of a bizarre fluid called oobleck. Perched next to carbon on the Periodic Table of Elements, boron is a metalloid, a substance with both metallic and nonmetallic properties.s part of borax, boron is a very common household element that is found in many detergents. (Pro tip: A borax-sugar solution will also kill ants!) It's also in the recipe for the science-fair goop oobleck, a liquid with some very strange properties.

How can you melt down nickel? As shown in Figure 1(1), when alloyed with nickel, a mere 3.6 wt% boron will lower the melting point by 652° F to 1999° F (1093° C). The lower melting point allows us to use nickel-boron filler metals to braze a wide variety of metals at temperatures far below their melting points. Although boron serves an important function in lowering the melting point of brazing filler metals, when alloyed alone with nickel, boron has some disadvantages.

Reading: Physical Characteristics of Minerals Luster describes the reflection of light off a mineral’s surface. Mineralogists have special terms to describe luster. One simple way to classify luster is based on whether the mineral is metallic or non-metallic. Minerals that are opaque and shiny, such as pyrite, have a metallic luster. Minerals such as quartz have a non-metallic luster. Luster is how the surface of a mineral reflects light. It is not the same thing as color, so it crucial to distinguish luster from color. For example, a mineral described as “shiny yellow” is being described in terms of luster (“shiny”) and color (“yellow”), which are two different physical properties.

- The term luster is used to describe the way a mineral surface looks when light is reflecting off of it. Luster is considered a basic descriptive parameter for minerals but varies somewhat even within a single crystal, which limits the term’s usefulness in categorizing gemstones and minerals.alc is an example of a mineral with a pearly luster. The term resinous is used to denote minerals that resemble resin, such as sphalerite. Minerals with a greasy luster appear as though they have a layer of oil or fat coating them. An example of a mineral with a greasy luster is graphite.
