1.1 Amorphous Network and Thermal Stability

(Quartz Crucibles)

Quartz crucibles are high-temperature containers produced from fused silica, a synthetic kind of silicon dioxide (SiO TWO) originated from the melting of natural quartz crystals at temperatures surpassing 1700 ° C.

Unlike crystalline quartz, integrated silica has an amorphous three-dimensional network of corner-sharing SiO ₄ tetrahedra, which imparts exceptional thermal shock resistance and dimensional security under quick temperature level adjustments.

This disordered atomic structure stops cleavage along crystallographic planes, making integrated silica much less prone to cracking during thermal cycling compared to polycrystalline ceramics.

The product displays a low coefficient of thermal development (~ 0.5 × 10 ⁻⁶/ K), among the lowest amongst engineering products, enabling it to withstand severe thermal gradients without fracturing– a crucial building in semiconductor and solar battery manufacturing.
