Quartz crucibles are behind the growth of silicon crystals ...
According to the SiO2 crystal phase transformation conditions, β-squared quartz is precipitated from fused silica at high temperatures during the sintering process, and at about 270°C during the cooling process, β-squared quartz is transformed into α-squared quartz, a process that reduces the volume by about 2.8%, which can damage the ...
