Porous quartz glass plate is an advanced functional material that combines the excellent performance of quartz glass with controllable porous structure. It is not "foam glass" in the traditional sense, but forms a uniform and connected nano or micro pore network in the glass matrix through precision technology. This unique structure enables it to maintain the core advantages of quartz glass such as high purity, high temperature resistance, and corrosion resistance, while possessing a huge specific surface area and excellent fluid handling capabilities, making it an ideal choice for high-end filtration, separation, catalysis, and thermal management fields.

Frequently Asked Questions (FAQ) about Porous Quartz Glass Plates

Q1: What is the difference between porous quartz glass plate and ordinary quartz glass plate?

A: The core difference lies in the internal structure. Ordinary quartz glass is dense and pore free, while porous quartz glass plates form a large number of uniformly distributed and interconnected micropores or nanopores inside through special processes such as phase separation heat treatment and acid treatment. This gives it a huge internal surface area that can adsorb, carry, or separate fluids, which ordinary quartz glass does not possess.

Q2: What is the maximum temperature that this material can withstand?

A: Porous quartz glass inherits the excellent heat resistance of quartz glass, and its long-term use temperature can reach above 1100 ℃, and it can withstand higher temperatures (close to 1200 ℃) in a short period of time. This enables it to maintain structural stability even in extreme high temperature environments, which is unmatched by many polymer porous materials.

Q3: What specifications and sizes of customized services can you provide?

A: We provide comprehensive customized services. In addition to standard sheet sizes, we can customize porous quartz glass products with different thicknesses (from a few millimeters to tens of millimeters), pore sizes (nanometer to micrometer), porosities, and special shapes (such as circular, ring-shaped, tubular, etc.) according to your specific application needs, ensuring perfect compatibility with your equipment and process.

Can porous quartz glass panels be reused?

A: Okay. Thanks to its extremely high chemical stability and mechanical strength, porous quartz glass plates can be reused multiple times after appropriate cleaning, drying, or high-temperature calcination treatment without significant performance degradation, greatly reducing the long-term usage cost for users.

Resolve your core challenge

Porous quartz glass plates are designed to solve precision application challenges in extreme environments. It can provide you with stable and reliable filtration, separation, catalysis, or thermal protection functions under harsh conditions such as strong acid, strong alkali, high temperature, and high pressure. Whether it is microfiltration that requires precise control of fluid flow rate, catalyst support in high-temperature reactors, or efficient desiccant in precision optical equipment, it can guarantee the stability and efficiency of your core process with its outstanding performance.

Analysis of the advantages and disadvantages of porous quartz glass plates

advantage:

Excellent chemical corrosion resistance: Its main component is high-purity silicon dioxide (SiO ₂), which hardly reacts with any acid, alkali, or organic solvent except hydrofluoric acid and hot phosphoric acid, making it suitable for the most demanding chemical environments.

Excellent high temperature resistance: With an extremely low coefficient of thermal expansion and good thermal stability, it can withstand drastic temperature changes without bursting. Its long-term working temperature can reach up to 1100 ℃, meeting the high temperature requirements of aerospace, semiconductor and other fields.

High mechanical strength and rigidity: Compared to porous materials such as polymers, its inorganic glass skeleton provides extremely high mechanical strength and dimensional stability, which is not easily deformed or compressed, ensuring stable operation under high pressure differentials.

Controllable and uniform pore structure: narrow pore size distribution, precise control of porosity and pore connectivity, enabling precise molecular level separation and filtration, ensuring process consistency and reliability.

Huge specific surface area: The rich internal pore network provides a huge specific surface area, making it an ideal adsorbent, catalyst carrier, or reaction substrate.

High purity and biological inertness: The material is pure, free of organic impurities, and does not breed bacteria. It is suitable for semiconductor, biopharmaceutical, and medical fields that require extremely high cleanliness.

Disadvantages:

Brittle material: Like all glass, porous quartz glass is a brittle material with limited impact and bending resistance. During installation and use, it is necessary to avoid severe mechanical impacts.

Processing difficulty and cost: The preparation process is complex, involving precise heat treatment and chemical treatment, and subsequent mechanical processing (such as cutting and drilling) is difficult, resulting in higher costs than ordinary porous materials.

Not resistant to strong alkali: Although it has excellent acid resistance, its silicon oxygen skeleton will be corroded in high-temperature and strong alkali environments, which limits its application to a certain extent.
