Custom Quartz Glass Chemical Acid Etching to Frosted Surface

Custom Quartz Glass Chemical Acid Etching to Frosted Surface

Quartz glass acid etching is a highly controlled chemical machining process, primarily utilizing hydrofluoric acid (HF) to selectively remove material from the surface of fused silica. This technique creates a uniformly frosted, matte finish characterized by excellent light diffusion and a smooth, non-abrasive texture, unlike mechanical methods.

Its applications are diverse and critical across high-tech industries. In optics, frosted quartz glass for optics is essential for creating diffuser plate quartz etched components that homogenize light in lasers and LED systems. The semiconductor sector relies heavily on semiconductor quartz component etching to produce precisely textured surfaces on etched quartz wafer carriers and process kits, enhancing wafer handling and minimizing particle contamination in cleanrooms.

Beyond technical uses, the process enables intricate decoration acid etched quartz for artistic and architectural elements. Similarly, laboratory glassware etching employs this method to apply durable, chemical-resistant markings and identifiers on quartz vessels and tools.

Requiring stringent safety protocols for HF handling, this process is valued for achieving complex geometries and fine details without inducing mechanical stress or micro-cracks, making it indispensable for manufacturing high-purity, performance-critical components.

Fused Quartz Glass Features:

Fused quartz glass is a special industrial glass made of silicon dioxide. It is a very good basic material. Quartz glass has a series of excellent physical and chemical properties.

1. High temperature resistance. The softening point of fused quartz glass is about 1730℃ and can be used for long time working under 1100℃~1250℃.  And working at 1450℃ in a short time.

2. Corrosion resistance. In addition to hydrofluoric acid, fused quartz glass is inert to other acids. Its acid resistance is 30 times as ceramic, 150 times as stainless steel. Especially, any other material cannot make a comparison with chemical stability of fused quartz at high temperature

3. The thermal stability is good. Thermal expansion coefficient is extremely small. And it can withstand severe temperature changes such that heating up to 1100℃ and putting it in normal temperature water will not crack.

4. The light transmittance is good. Quartz glass has good transmittance in the whole spectral band from ultraviolet to infrared. The transmittance of the visible light is above 95%. Especially in the ultraviolet spectrum band and the maximum transmittance is over 85%.

5. The electrical insulation performance is good. Resistance value of quartz glass equaling to 10000 times of ordinary glass. It is an excellent electrical insulating material and has good electrical properties even under high temperature.
