Borosilicate glass plays an important role in modern life and industry due to its excellent physical properties and aesthetic value. This article will give you an in-depth look at the features, applications and benefits of borosilicate glass, from kitchen items to laboratory utensils, and discover why this material is the first choice in many fields.

The unique charm of borosilicate glass

Excellent heat resistance

High borosilicate glass has a very low coefficient of thermal expansion, which means it can maintain a stable shape and size under extreme temperature differences. Whether it is taken out of the refrigerator and heated immediately, or used on a high-temperature flame, there will be no cracking or deformation, which makes it an ideal choice in the kitchen and laboratory.

Superior corrosion resistance

High borosilicate glass has good resistance to most acid and alkali solutions and will not be corroded or dissolved. This characteristic makes it particularly suitable for the storage and handling of chemicals, which are widely used in chemical equipment and laboratory utensils.

Good light transmission and beautiful appearance

High borosilicate glass has a high transparency, light through almost no loss, showing a clear and bright effect. This not only increases the aesthetics of the product, but also allows better observation of the internal conditions, especially for cooking utensils and laboratory observations.

Application fields of borosilicate glass

Kitchen Supplies

Cooking appliances

The baking pan, stew lid and baking mold made of high borosilicate glass are not only resistant to high temperatures, but also easy to clean. They are essential items in modern kitchens. They not only enhance the cooking experience, but also ensure food safety and hygiene.

Tableware and Storage Containers

High borosilicate glass bowls, cups and storage tanks are not only beautiful, but also safe and healthy. These products are not easy to scratch, are not easy to breed bacteria, and are very suitable for long-term use and food storage.

Labware

Beakers and tubes

The beakers and test tubes commonly used in the laboratory are usually made of high borosilicate glass because they can withstand high temperature and chemical corrosion to ensure the accuracy and safety of the experiment.

Bottle and Reactor

Experimental bottles and reactors made of high borosilicate glass have high transparency, easy to observe the reaction process, and strong corrosion resistance. They are important tools for chemical experiments and research.

Industry and Manufacturing

Chemical Equipment

High borosilicate glass is widely used in chemical equipment, such as pipes, valves and reactors. Its corrosion resistance and temperature resistance ensure the long-term stable operation of the equipment.

Optics

Because of its low expansion coefficient and high transparency, high borosilicate glass is often used in the manufacture of optical lenses, optical fibers and other precision optical components to ensure image quality and transmission efficiency.

Technical advantages of borosilicate glass

Low expansion coefficient

The thermal expansion coefficient of borosilicate glass is extremely low, about 1/3 that of ordinary glass. This feature makes it perform well in environments with large temperature changes, reducing the risk of damage due to thermal stress.

High strength and toughness

Despite its light texture, high borosilicate glass has high strength and toughness, and can withstand greater impact without being easily broken. This is particularly important for occasions that require frequent handling and use.

Environmentally friendly and non-toxic

High borosilicate glass does not contain any harmful substances and fully complies with food safety standards. It can be safely used in food contact and will not cause harm to the human body.

Production process of borosilicate glass

Raw material preparation

The main components of high borosilicate glass include silicon dioxide (SiO₂), boron oxide (B₂) and small amounts of sodium, potassium and other fluxing agents. These raw materials are carefully proportioned to ensure optimal performance of the final product.

Melting and Forming

The mixed raw materials are melted in a high-temperature furnace, and then formed into the desired shape by blowing, pressing, etc. This process requires strict temperature control and technical operation to ensure product quality.

Cooling and Inspection

The formed high borosilicate glass product needs to be slowly cooled to eliminate internal stress. Subsequently, each product will undergo strict quality inspection to ensure that there are no bubbles, cracks and other defects.

Daily care of borosilicate glass

Cleaning and Disinfection

Borosilicate glass products can be cleaned with mild detergent and water, and stubborn stains can be removed with a soft brush if necessary. For thorough disinfection, the product can be put into boiling water and boiled for a few minutes.

Storage and Maintenance

After use, the high borosilicate glass products should be wiped dry and stored in a dry and ventilated place to avoid collision and heavy pressure. Regularly check whether there are scratches or damage, and replace the problematic products in time.
