What are the characteristics of white corundum produced by flame fusion synthesis

We only know that white corundum is made by smelting, but we may not know that it also includes several smelting processes, and flame fusion synthesis is one of them. How much do you know about this? Let's take a look.
The white corundum produced by flame fusion synthesis has some obvious characteristics, which we can easily identify. For example, the color of this kind of white corundum is pure and gorgeous; Its crystal shape is generally pear-shaped; In addition, some growth patterns with curved arcs can be seen on the white corundum.
In addition, bubbles are another important basis for distinguishing white corundum products synthesized by flame melting method. Although these bubbles are small, they can be easily seen because of their large refractive index compared with other products. Pear crystal of white corundum produced by flame fusion synthesis will have transverse cracks due to the effect of stress, so it is obvious that it can be observed.
Through the description of these characteristics, we can easily observe the process by which a white corundum product is processed.
