What is the benefit of using boron oxide over boric acid in lining of induction furnace?
As per my knowledge Boric acid dissociates into Boron oxide by escape of water molecules from boric acid near to 300 deg centrigrade; hence bonding may be weakened. But in case of Boron oxide use, there is no dissociation of Boron oxide.
What is the cupel used in metal refinery called?
The cupel used in metal refining is typically called a "cupel." It is a porous container made from materials like bone ash or clay, designed to absorb impurities during the process of fire assay. In this process, precious metals like gold and silver are separated from base metals, allowing for the recovery of pure metal. The cupel's ability to absorb lead and other oxides is crucial in achieving high purity levels in the refined metal.
How do you calculate pcd in submerged arc furnace?
The PCD (Power Consumption per ton of metal produced) in a submerged arc furnace can be calculated using the formula: [ \text{PCD} = \frac{\text{Total Power Input (kWh)}}{\text{Tons of Metal Produced}} ] To determine the total power input, you need to sum the electrical energy consumed during the smelting process over a specific period. This value is then divided by the total weight of the metal produced in that same period to obtain the PCD in kWh per ton of metal.
What causes welding hose to be charred?
Laying on hot metal, or having slag fall on it.
Melting point for tin?

What is the formula of boron nitride?
The chemical formula of boron nitride is BN.
What is boron nitride?
Boron nitride is a synthetic compound composed of boron and nitrogen atoms. It can exist in various forms, including hexagonal boron nitride (h-BN) and cubic boron nitride (c-BN), with unique physical and chemical properties. Boron nitride is known for its high thermal conductivity, chemical inertness, and lubricating properties.
What is the name of the compound for boron?
The compound for boron is Boron Nitride.
Is boron nitride an element or compound?
Boron nitride is a compound made of both boron and nitrogen atoms, with a chemical formula of BN.
Why is boron nitride a conductor?
Boron nitride can be a conductor under certain conditions due to the presence of free electrons that can move to conduct electricity. This typically occurs in hexagonal boron nitride, which has a similar structure to graphene, allowing for electron mobility. However, boron nitride is more commonly known for its insulating properties.
What is the correct name for the covalent compound BN?
The correct name for the covalent compound BN is boron nitride.
Why boron nitride is not a conductor?
Boron nitride is not a conductor because it has a wide band gap between its valence and conduction bands, which makes it an insulator. The electrons in boron nitride are tightly bound, and there are no available free electrons to carry charge.
What is the formula for boron nitrate?
The chemical formula for boron nitride is BN.
Formula writing boron nitride?
The chemical formula for boron nitride is BN. It consists of equal numbers of boron and nitrogen atoms in a 1:1 ratio.
How does nasa space program use Boron Nitride?
NASA used Boron Nitride in many different ways. It was used as a catalyst when starting Saturn rocket engines. Boron Nitride is also used in one form to protect the outside of the spacecraft. Boron Nitride is one of the hardest chemicals known to man.
The nitride of this element can be as hard as a diamond?
This is Boron
What is boron nitrogen?
Boron nitride is a binary compound made up of boron and nitrogen atoms. It exists in several forms, including hexagonal boron nitride (h-BN) and cubic boron nitride (c-BN), with distinct properties such as high thermal conductivity, chemical stability, and hardness. It is commonly used in industries like electronics, ceramics, and lubricants.
