Milky opaque quartz plate

The milky opaque quartz plate is a special type of quartz material made from 99.9% high-purity quartz raw materials through advanced electro-fusion technology. With its uniformly distributed micrometer-sized closed pores structure inside, this material has extremely low thermal conductivity and excellent infrared reflection performance. As an ideal component for semiconductor heat treatment, high-temperature furnaces insulation, and the optical field, it can not only effectively reduce heat loss but also maintain excellent chemical stability and structural strength in extremely high-temperature environments, meeting the strict requirements of global high-end manufacturing.

FAQ

Q1: What is the core difference between the milky white opaque quartz plate and the traditional transparent quartz plate?

A: The core difference lies in their microscopic structure and optical and thermal properties. The milky white quartz plate contains a large number of tiny closed pores inside, which makes it opaque and milky white, and has extremely low thermal conductivity and high infrared reflectivity, making it ideal for heat insulation and preservation; while the transparent quartz plate has excellent light transmission properties and is mainly used as optical windows or observation windows, with much poorer heat insulation performance than the milky white quartz.

Q2: What customization services can you provide in terms of specifications and dimensions?

A: We offer comprehensive size and shape customization services. Whether it's circular, square, or rectangular plates with a thickness ranging from 2 to 500mm, or custom-shaped parts based on drawings, we can precisely process them. Additionally, we can also provide deep processing services such as punching, cutting, mold opening, grinding and polishing, fully meeting the personalized needs of customers.

Q3: What is the specific role of this material in semiconductor manufacturing?

A: In the semiconductor field, it is mainly used in high-temperature heat treatment processes such as oxidation, diffusion and annealing. As insulation tanks, heat insulation baffles, flanges and other components in vertical or horizontal furnaces, it can minimize heat loss and ensure uniform temperature in the furnace, while its high purity characteristic avoids process contamination.

Value: Addressing Key Challenges in High-Temperature Environments

From the user's perspective, choosing our milky white opaque quartz plate means you will obtain a set of efficient high-temperature thermal management solutions. We are committed to addressing the challenges you face in high-temperature equipment operation, such as excessive energy consumption, uneven temperature distribution, short lifespan and easy leakage of traditional insulation materials. By adopting our high-performance quartz plate, you can not only significantly reduce the energy consumption and production costs of the equipment, but also greatly improve the stability and yield rate of the thermal processing process, ensuring continuous and efficient operation in high-end manufacturing fields such as semiconductors, photovoltaics and chemicals.

Advantages and Application Analysis

1. Outstanding Insulation and Energy-saving Performance

Our white opal quartz plates are prepared through advanced electric melting technology, with the average bubble diameter being less than 15 μm. This unique microstructure endows the material with extremely high infrared reflectivity and extremely low thermal transmittance. In applications involving high-temperature furnaces, it can effectively block heat radiation, confine heat within the processing chamber, and significantly reduce energy loss, thereby improving application costs.

2. Excellent Surface Quality and Sealing Performance

Compared to traditional gas refining technology-produced quartz products, our electrically melted white opal quartz maintains a smooth and flat surface after firing processing, without rough protrusions or depressions. This characteristic significantly enhances the tightness between quartz components and devices, effectively preventing leakage issues due to poor sealing, and also makes the material easier to clean, reducing maintenance time.

3. High Purity and High-Temperature Chemical Stability

The product uses 99.9% high-purity quartz raw materials, with extremely low metal impurity content. In advanced semiconductor manufacturing processes, it can withstand chemical corrosion at high temperatures and will not release impurity particles into the process environment, ensuring high cleanliness in wafer processing. Its density is approximately 2.2 g/cm³, featuring both lightweight and high-strength characteristics.

4. Flexible Customized Processing Capability

We understand that different equipment has extremely high precision requirements for components. Therefore, we offer a one-stop service from raw materials to precise processing. Customers can request that we process the quartz plates into specific thicknesses (the thinnest can reach below 2 mm, with regular thicknesses ranging from 2 to 500 mm), diameters or lengths and widths, and perform high-precision planar grinding and edge chamfering.

Customer Application Cases

Case 1: Thermal Insulation Upgrade for a Vertical Furnace of a Semiconductor Equipment Manufacturer

Challenges: The client encountered difficulties in finding a thermal insulation material for their new 12-inch wafer vertical diffusion furnace. The original ordinary quartz insulation baffles would crystallize on the surface and become rough after long-term operation at high temperatures, resulting in minor leaks at the sealing area between the furnace body, affecting the purity of the furnace atmosphere and causing significant heat loss, thereby increasing power costs.

Solution: The client introduced our custom-made electrically fused milky white opaque quartz insulation tanks and baffles. Based on the furnace structure, we provided high-precision arc-shaped quartz components and carried out special surface polishing treatment.

Application Effect: After replacing the new material, the client reported that the temperature uniformity inside the furnace was significantly improved, and the heat loss was reduced by approximately 15%. More importantly, due to the smooth and dense surface of the electrically fused quartz, the sealing performance was significantly enhanced, completely eliminating the risk of gas leakage, and the equipment maintenance cycle was extended by more than 30%.

Case 2: Observation and Protection of High-Temperature Reactors in the Photovoltaic and Chemical Industries

Challenges: A photovoltaic material production enterprise needed to install protective windows and inner linings at specific parts of the high-temperature reactor, requiring the material to be able to withstand temperatures above 1100℃, while also having certain shading properties to protect external sensors from strong light interference, and must resist the corrosion of acidic gases.

Solution: We recommended a 10mm thick milky white opaque quartz plate to the client and cut it into square flange structures according to the drawings.

Application Effect: The opaque characteristic of the milky white quartz perfectly blocked the internal strong light radiation, protecting the external precision instruments. At the same time, its excellent acid and alkali corrosion resistance ensured a long-term service life in harsh chemical environments, helping the client achieve stable production without faults for 6 consecutive months.
