Xiamen university sends diamond rings to freshmen of physics department. Is this a real diamond?
This is not a real diamond, it's mosan stone. Recently, Xiamen University's official recruitment WeChat exposed the meeting prepared by the college to recruit students from the Strong Foundation Program. Among them, "physics" is the most eye-catching, and it turns out to be a "diamond ring". It is reported that this "diamond ring" is made of Mosan stone.

Mosan stone is the brightest gem in the world, which is second only to diamond in hardness, but even surpasses diamond in luster and fire color. However, according to the professors from the School of Physical Science and Technology of Xiamen University, Mosanite is actually silicon carbide, which is the most advanced scientific and technological achievement in the semiconductor industry today and is regarded as the third generation silicon carbide crystal in the semiconductor industry.

Extended data

This university has special expectations for its students.

According to reports, after more than 20 years of accumulation, the institute has made a series of achievements in silicon carbide ultraviolet point detectors, power devices and material growth. In vernacular Chinese, professors can synthesize silicon carbide by themselves. They use good crystals as chips and process the remaining materials into "diamond rings".

This "diamond ring" is also full of profound meaning. It says: I will give you a diamond ring, and I will love you all my life. I look forward to loving Xiamen University and physics with you. Gifts from other colleges are relatively unpretentious.
