Specification of Hich purity quartz material silica sand superfine silica powder for optical glass crucible

Our high pureness quartz material silica sand and superfine silica powder meet strict needs for optical glass crucible manufacturing. The raw quartz sand provides consistent bit dimension circulation. This guarantees uniform melting actions inside crucibles. You obtain marginal batch variation. Our processing achieves extraordinary chemical purity. Complete metal contaminations remain below 50 parts per million. Iron material is especially reduced, often under 10 parts per million. This pureness stops unwanted coloring or flaws in the last optical glass. The material keeps very low degrees of alkali steels. This prevents devitrification issues inside the crucible throughout high-temperature melting.

The superfine silica powder boasts a precisely managed particle dimension. Typical bit diameter ranges from 1 micron to 5 microns. This fine dimension advertises rapid melting and superb homogeneity in the molten glass batch. It minimizes crucible use as well. Both sand and powder undertake rigorous washing and acid leaching. This gets rid of surface pollutants efficiently. We utilize advanced magnetic separation. This removes ferrous particles additionally. The resulting material displays high brightness and illumination.

Our quartz product offers exceptional thermal security. It withstands the severe temperature levels inside optical glass melting heating systems. The material stands up to thermal shock successfully. Crucibles made with our silica program minimized cracking and contortion. This expands crucible service life substantially. You attain cleaner glass melts. Bubble formation decreases. Light transmission residential properties in the last optical glass boost. Our silica makes sure constant glass top quality batch after set. It is the trusted choice for requiring optical applications requiring clearness and accuracy.

Applications of Hich purity quartz material silica sand superfine silica powder for optical glass crucible

High purity quartz silica sand and superfine silica powder are essential for excellent optical glass crucibles. This product should be remarkably pure. Contaminations like iron or aluminum are very negative. Even tiny amounts can wreck the glass. They cause bubbles, touches, or cloudiness. This pureness is non-negotiable for clear lenses, optical fiber, and precision tools.

Producing this product needs careful work. We start with selected all-natural quartz crystals. These crystals go through rigorous cleansing. After that comes crushing and grinding. The grinding creates superfine silica powder. The powder bits are extremely tiny and uniform. This great size is vital. It enables the powder to load densely inside the crucible mold. Thick packing ways much less air caught inside. Much less air means fewer bubbles later on. This great powder also thaws equally. Constant melting is essential for ideal glass.

The crucible itself should do completely. Crucibles encounter severe warm inside furnaces. Thermal shock is a continuous threat. Unexpected temperature level changes can fracture weaker products. Our high-purity quartz handles this tension well. It withstands thermal shock properly. This product likewise endures chemical rust. Liquified glass is very corrosive. Impure silica can liquify or infect the melt. Our pure material remains stable. This stability protects the molten glass. It makes sure the glass stays uncontaminated.

The outcome is an exceptional crucible. It makes it possible for the production of remarkable optical glass. This glass has excellent light transmission. It has high clarity and strength. Manufacturers rely on this material. It ensures crucible reliability and long life span. Regular outcomes are attainable batch after set.

5 FAQs of Hich purity quartz material silica sand superfine silica powder for optical glass crucible

Here are 5 common questions about our high-purity quartz silica sand and superfine silica powder for optical glass crucibles:

What makes your silica sand high-purity?
Our quartz material undergoes strict processing. We remove almost all impurities. The final product has incredibly low levels of metals like iron, aluminum, and potassium. Typical purity exceeds 99.995% SiO2. This level is essential for clear optical glass.

Why is superfine silica powder used?
Superfine powder melts uniformly inside the crucible. This consistency is vital. It prevents bubbles and defects in the final optical glass. The fine particles pack densely. This improves melting efficiency.

How do impurities affect optical glass crucibles?
Impurities cause big problems. They create defects like bubbles or stones in the glass. They also reduce the crucible’s lifespan. High temperatures make impurities react with the crucible material. This weakens it faster. Our low impurity levels minimize this risk.

How do you ensure quality consistency?
We use advanced processing and strict lab tests. Every batch undergoes checks for purity, particle size, and moisture. We follow precise specifications. Traceability is key. We know the source and process for each shipment.

Is moisture control important?
Yes, moisture control is critical. Excess water causes issues during melting. It can lead to bubbles or unpredictable reactions in the crucible. Our material is carefully dried and packed. We use moisture-proof packaging to keep it dry until use.
