Boron Trioxide Powder Description :
Boron trioxide Powder is one of the oxides of boron. It is a white, glassy solid with the formula B2O3.
It is almost always found as the vitreous (amorphous) form; however, it can be crystallized after extensive annealing (that is, under prolonged heat).
Another method is heating boric acid above ~300 °C. Boric acid will initially decompose into steam, (H2O(g)) and metaboric acid (HBO2) at around 170 °C and further heating above 300 °C will produce more steam and diboron trioxide. The reactions are:
H3BO3 → HBO2 + H2O
2 HBO2 → B2O3 + H2O
Boric acid goes to anhydrous microcrystalline B2O3 in a heated fluidized bed. A carefully controlled heating rate avoids gumming as water evolves.
Molten boron oxide attacks silicates. Internally graphitized tubes via acetylene thermal decomposition are passivated.
Crystallization of molten α-B2O3 at ambient pressure is strongly kinetically disfavored (compare liquid and crystal densities).
The threshold conditions for the crystallization of the amorphous solid are 10 kbar and ~200 °C.
Its proposed crystal structure in enantiomorphic space groups has been revised to enantiomorphic space groups P3121(#152); P3221(#154) (e.g., α-quartz).
Boron oxide will also form when diborane (B2H6) reacts with oxygen in the air or trace amounts of moisture.

Hafnium Carbide Powder
Product Hafnium Carbide Powder
Colour Gray Powder Purity ≥ 99.9% Particle size 1-10 µM (customizable) Ingredient/MF HfC Product Code NCZ-C-103/20 CAS Number 12069-85-1 Brief Description of Hafnium carbide powder HfC:
Hafnium carbide ( HfC) is a chemical compound of hafnium and carbon
With a melting point of about 3900 °C it is one of the most refractory binary compounds known.
However, it has low oxidation resistance, with the oxidation starting at temperatures as low as 430 °C
Hafnium carbide is usually carbon deficient and therefore its composition is often expressed as HfCx (x = 0.5 to 1.0). It has a cubic (rock-salt) crystal structure at any value of x
Application of Hafnium carbide powder HfC:
- Used for preparation of ultra-high temperature ceramics
- The reactant in the synthesis of hafnium-containing organometallic polymers
- Used as an additive in alloys
- Used in coatings
- Widely used in microelectronics, semiconductor, aerospace high-temperature resistant material, coating materials, ceramic materials, ceramic target material, etc.

Silicon Carbide Powder
Product Silicon Carbide Powder
Colour Black Powder Purity ≥ 99.9% Particle size 1-10 µM (customizable) Ingredient/MF SiC Product Code NCZ-C-104/20 CAS Number 409-21-2 Silicon Carbide Powder Description:
Silicon carbide is produced in the same way as Black silicon Carbide except for some differences in the raw material. Its crystallization has higher purity and hardness. Green silicon carbide is suitable for processing hard alloy, metallic and non-metallic materials with hard and brittle features such as copper, brass, Aluminum, magnesium, jewel, optical glass, ceramics, etc.
Silicon Carbide Applications:
- One of the best properties of silicon carbide is that it is resistant to alkali and acids.
- It retains strength when applied at high temperatures.
- It shows good electrical conductivity and shock resistance capacity and for this reason, it is preferred for applying in an electric furnace to heat elements.
- It is compatible to apply under extreme conditions of applications.
- Apart from that, this chemical component also shows considerable thermal expansion and conductivity.
- It is an ideal component for applications requiring good flexural strength.
- We provide this product after evaluating the properties, ingredients, and applicability to cover a wide range of industrial usages.
Advantages:
- Large melting furnace, longer melting time, lead to more crystallization, bigger crystals, higher purity, and fewer impurities.
- Beckman coulter particle size distribution instrument.
- The laboratory is registered at the government Import and Export Inspection Bureau.

Ferrochrome Nitride Powder
Product Name: Ferrochrome Nitride Powder
Product Ferrochrome Nitride Powder Colour Black Powder Purity ≥ 99.9% Particle size 1-10 µM (customizable) Ingredient/MF FeCrN Product Code NCZ-CN-151/20 CAS Number 7439-89-6, / 24094-93-7 Ferrochrome Nitride Powder Description:
Ferrochrome nitride is widely used in electric furnace and oxygen converter smelting nitrogen steel. Nitrogen is an element of austenite formation,
It is used as a component to add chromium manganese and chromium manganese nickel stainless steel to replace the shortage of nickel.
Ferrochrome Nitride Powder Application:
Ferrochrome, or ferrochromium (FeCr) is a type of ferroalloy, that is, an alloy of chromium and iron, generally containing 50 to 70% chromium by weight.
Ferrochrome is produced by electric arc carbothermic reduction of chromite. Most of the global output is produced in and India, which have large domestic chromite resources. Increasing amounts are coming from Russia and China.
Production of steel, especially that of stainless steel with a chromium content of 10 to 20%, is the largest consumer and the main application of ferrochrome.
Ferrochrome production is essentially a carbothermic reduction operation taking place at high temperatures. Chromium ore (an oxide of Cr and Fe) is reduced by coal and coke to form the iron-chromium alloy.
The heat for this reaction can come from several forms, but typically from the electric arc formed between the tips of electrodes at the bottom of the furnace and the furnace hearth.
This arc creates temperatures of about 2,800 °C (5,070 °F). In the process of smelting, huge amounts of electricity are consumed, making production very expensive in countries where power costs are high.
The tapping of the material from the furnace takes place intermittently. When enough smelted ferrochrome has accumulated in the furnace hearth.
The tap hole is drilled open and a stream of molten metal and slag rushes down a trough into a chill or ladle. Ferrochrome solidifies in large castings that are crushed for sale or further processed.
Ferrochrome is generally classified by the amount of carbon and chrome it contains.
The vast majority of FeCr produced is “charge chrome” from South Africa, with high carbon being the second largest segment followed by the smaller sectors of low carbon and intermediate carbon material.
