High Purity Lab Diamond Crystal

The use of silicon carbide

1. LEDs

The phenomenon of electroluminescence was discovered in 1907 using silicon carbide and the first commercial LEDs were based on SiC. Yellow LEDs made from 3C-SiC were manufactured in the Soviet Union in the 1970s[57] and blue LEDs (6H-SiC) worldwide in the 1980s. The production was soon stopped because gallium nitride showed 10–100 times brighter emission. This difference in efficiency is due to the unfavorable indirect bandgap of SiC, whereas GaN has a direct bandgap which favors light emission. However, SiC is still one of the important LED components – it is a popular substrate for growing GaN devices, and it also serves as a heat spreader in high-power LEDs.

2. Astronomy

The low thermal expansion coefficient, high hardness, rigidity and thermal conductivity make silicon carbide a desirable mirror material for astronomical telescopes. The growth technology (chemical vapor deposition) has been scaled up to produce disks of polycrystalline silicon carbide up to 3.5 m (11 ft) in diameter, and several telescopes like the Herschel Space Telescope are already equipped with SiC optics, as well the Gaia space observatory spacecraft subsystems are mounted on a rigid silicon carbide frame, which provides a stable structure that will not expand or contract due to heat.

3.Thin filament pyrometry

Test flame and glowing SiC fibers. The flame is about 7 cm (2.8 in) tall.

Silicon carbide fibers are used to measure gas temperatures in an optical technique called thin filament pyrometry. It involves the placement of a thin filament in a hot gas stream. Radiative emissions from the filament can be correlated with filament temperature. Filaments are SiC fibers with a diameter of 15 micrometers, about one fifth that of a human hair. Because the fibers are so thin, they do little to disturb the flame and their temperature remains close to that of the local gas. Temperatures of about 800–2500 K can be measured.

Moissanite  Maintenance

Although Moissanite is the hardest substance in nature, it is also very brittle, and it is easy to break when it is hit or crushed by external force. Therefore, when doing sports, heavy physical labor, do not wear Moissanite jewelry, so as not to accidentally collide with hard objects, causing Moissanite to cause permanent and irreparable defects.

How to clean

Cold water immersion

Use a small bowl or teacup to soak the Moissanite in water for about 30 minutes, then use a small brush to gently scrub around moissanite Stone, then wave it in the water for a while, then take it out and wipe it with a paper towel.

Brand story

Hmois

In 1893, The French Nobel Prize winner Dr. Henry Moissan found these sparkling pieces of Sic.

In 1905, To order Dr. Henri moissan, the newly found gem was named Moissanite

Our company in order to celebrate the Dr. Henry Moissan, So named our brand to Hmois
