Introduction to Carborundum Crystal

Overview of Carborundum Crystal

Carborundum crystal is a synthetic compound of silicon and carbon. Different from the common green or black silicon carbide, carborundum crystal shows a variety of colors and is sometimes called rainbow carborundum. 

This color is caused by the silicon carbide structure and various impurities present in the crystal. These impurities interfere with light and create a spectrum, creating a unique rainbow aesthetic.

High Hardness; Sharpness;Thermal Stability and Chemical Resistance are just a few advantages available with these unique abrasives.

Longevity; Versatility; Cost-Effectiveness and Low Expansion Coefficient are hallmarks of excellence for any construction material.

Innovations in Carborundum Crystal Manufacturing

Innovations in carborundum crystal manufacturing can significantly enhance its performance, quality, and applications. Below we introduce key innovative technologies.

3D Printing of Silicon Carbide

3D Printing of Silicon Carbide:

At present, 3D printing using silicon carbide has drawn much interest and research.

Emergence of 3D printing technology marks an advancement in additive manufacturing technology. By rapidly prototyping parts through 3D printing technology, rapid prototyping timeframes can be drastically decreased – cutting product development time down significantly!

Physical Vapor Transport (PVT):

commonly referred to as sublimation method, has been refined in order to produce high-purity SiC single crystals of large sizes with defect-free surfaces.

The process involves sublimating silicon carbide powder before allowing it to recrystallize on seed crystals at slightly cooler temperatures; innovations relating to temperature gradients, growth atmospheres and pressure have resulted in larger, defect-free crystals.
