Tungsten carbide, a remarkable compound known for its exceptional hardness and durability, has become an indispensable material in various industries. From cutting tools to jewelry, this versatile substance finds applications in numerous fields. In this comprehensive guide, we'll explore the various sources and locations where you can find tungsten carbide, its properties, and its wide-ranging applications.
Understanding Tungsten Carbide
Before delving into where to find tungsten carbide, it's crucial to understand what it is and why it's so valuable. Tungsten carbide is a chemical compound consisting of equal parts tungsten and carbon atoms[3]. It's renowned for its extraordinary hardness, which is second only to diamond on the Mohs scale, ranking between 9 and 9.5[6].
Properties of Tungsten Carbide
Tungsten carbide boasts several remarkable properties that make it highly sought after:
1. Extreme hardness and wear resistance
2. High density (about twice that of steel)
3. Excellent heat resistance
4. High electrical conductivity
5. Corrosion resistance
These properties contribute to its longevity and make it an ideal material for various applications across different industries[1][2].
Natural Sources of Tungsten
While tungsten carbide itself is not found naturally, its primary component, tungsten, is a naturally occurring element. Tungsten is relatively rare, with only about 1.25 grams found in every 1000 kilograms of the Earth's crust[6]. It's believed to have been formed through supernova explosions.
Mining Locations
Tungsten is primarily mined from two types of ore deposits:
1. Wolframite ((Fe,Mn)WO4)
2. Scheelite (CaWO4)
The largest deposits of tungsten are found in:
- China
- Vietnam
- Russia
- Bolivia
- Austria
Industrial Production of Tungsten Carbide
Since tungsten carbide doesn't occur naturally, it must be synthesized. The production process involves several steps:
1. Mining and processing of tungsten ore
2. Conversion of tungsten ore to tungsten metal powder
3. Mixing of tungsten powder with carbon
4. Heating the mixture to high temperatures
Manufacturing Process
Tungsten carbide is typically produced by heating tungsten metal and carbon to temperatures between 1400°C and 2000°C[3]. Alternative methods include:
1. A lower-temperature fluid bed procedure using tungsten metal or blue WO3 with a CO/CO2 mixture and H2 between 900°C and 1200°C[3].
2. Heating WO3 with graphite at 900°C or in hydrogen at 670°C, followed by carburization in argon at 1000°C[3].
Where to Find Tungsten Carbide Products
Now that we understand how tungsten carbide is produced, let's explore where you can find products made from this remarkable material.
Industrial Suppliers
Many industrial suppliers specialize in tungsten carbide products. These suppliers cater to various industries and offer a wide range of tungsten carbide items, from raw materials to finished products. Some well-known suppliers include:
