High-Purity Fused Quartz Ingot for Advanced Industrial
Detailed Diagram
Product Description of Quartz ingots
Fused Quartz Ingots are solid blocks of ultra-high-purity silicon dioxide (SiO₂), manufactured through precise high-temperature fusion processes. As the fundamental raw material in the quartz industry, fused quartz ingots provide the structural and performance foundation for a wide range of downstream quartz products, including tubes, rods, plates, wafers, capillaries, optical elements, and semiconductor quartz components.
Thanks to their exceptional purity, structural uniformity, thermal stability, and optical transparency, fused quartz ingots are widely used in semiconductor fabrication, optical engineering, photovoltaic manufacturing, and other high-end industrial applications where material reliability is critical.
Material Characteristics of Quartz ingots
Fused quartz ingots are produced from carefully selected high-purity quartz sand or synthetic SiO₂ feedstock. The melting and solidification process is tightly controlled to achieve a dense, homogeneous structure with minimal bubbles and striae.
Key material characteristics include:
-
Extremely low metallic impurity levels
-
Uniform internal structure suitable for precision machining
-
Excellent resistance to thermal shock
-
Stable performance under harsh chemical environments
These properties make fused quartz ingots an ideal starting material for precision quartz components.

FAQ of Quartz Glasses
Q1: What is the difference between fused quartz and fused silica?
A: Fused quartz is produced from natural quartz crystal melted at high temperature, while fused silica is synthesized from high-purity silicon compounds through chemical vapor deposition or hydrolysis. Fused silica typically has higher purity, better UV transmission, and lower impurity content than fused quartz.
Q2: Can quartz glass sheets withstand high temperatures?
A: Yes. Quartz glass sheets have excellent thermal stability and can operate continuously at temperatures up to 1100°C, with short-term resistance up to 1300°C. They also have extremely low thermal expansion, making them highly resistant to thermal shock.
Q3: Are quartz glass sheets resistant to chemicals?
A: Quartz is highly resistant to most acids, including hydrochloric, nitric, and sulfuric acids, as well as organic solvents. However, it can be attacked by hydrofluoric acid and strong alkaline solutions like sodium hydroxide.
Q4: Can I cut or drill quartz glass sheets myself?
A: We do not recommend DIY machining. Quartz is brittle and hard, requiring diamond tools and professional CNC or laser equipment for cutting or drilling. Improper handling may cause cracking or surface defects.
