· Fluorite enhances the fluidity of the slag (by reducing its melting point) and, as a result, makes it possible to remove sulfur and phosphorus from the steel into the slag. Consumption of fluorospar in the production of steel has increased from 2 to 10 kg or by 5 to 10% of the amount of lime....
Fluorite Meanings, Properties and Uses
· Originally, fluorite was called fluorospar or fluorspar. It is primarily an industrial mineral having a low melting point. It derives its name from the Latin term "fleure" which means "to flow". This refers to its use as a flux in the aluminum and steel smelting process....
Properties of Fluoropolymers
· The properties of PTFE high crystallinity, very high melting point (600 K), and very high melt viscosity do not allow its processing by the usual meltprocessing methods for plastics. Instead, similar to metal powder forming, the granular resins are processed by compression molding at ambient temperature followed by sintering above the crystalline melting point....
Why is the melting point of hydrogen fluoride lower than ...
· The melting point of hydrogen fluoride is °C, as compared to that of ammonia, which is °C. How does this make any sense? Both hydrogen fluoride and ammonia show hydrogen bonding, which "elevates" the boiling points of these two compounds when compared to the rest of the pnictogen and halogen hydrides....
Chemistry
As lattice energy increases, the melting point increases. Lattice Energy depends on two things: charge and size of each compound. The greater charge and smaller ionic radius result in a greater lattice energy. Charges. When these ionic compounds bond, each element forms a charge. Lithium Fluoride has a +1 and a 1 charge respectively....
