What is hollow-glass microsphere?
Hollow glass microspheres are also called microballoons. Their diameters range from 10 to 30 micrometers. Hollow spheres fill composite materials like lightweight concrete, syntactic foam or lightweight cement. The hollow spheres can be used to fill lightweight composite materials like syntactic polymer foam and lightweight concrete.
Hollow glass bead
This is a special type of glass bead that is less dense and has a lower thermal conductivity. This new micron-graded light material was developed during the 1950s and 60s. Its primary component is borosilicate. The particle size of the material is 10250mm with a wall thickness 12mm. Hollow glass beads feature high compressive strengths, a high melting temperature, high resistivity, a low thermal conductivity coefficient and small thermal conductivity.
Hollow glass microspheres
Micro balloons (also known as bubbles) are formed from borosilicate and sodium salt glass mixtures. They have low density, and they're resistant to heat and chemicals. The walls are made of
Glass microspheres
The spheres are typically rigid and about 10% thicker than their diameter. Spherical particles are available in a variety of densities ranging from 0.06g/C3 to 0.80g/C3, and particle sizes from 5um to180um. The wall thickness determines the compression strength of a hollow ball. This is expected as the greater density of the sphere increases the compressive strengths.

Hollow Glass Sphere Hollow Glass beads Product Performance:
Hollow glass microspheres consist of hollow glass microspheres at the micron level with a smoothed surface. It is made up of borosilicate, which is the main chemical component. The sphere is hollow and transparent under an electron microscope. Hollow glass beads possess low density, good strength, resistance to acid and alkali, low thermal conductivity and electrical insulation, among other qualities. These new materials are multi-functional and have excellent fluidity, chemical stability.

How do you make microspheres of glass?
1. Glass Powder Method
The glass powder method involves passing pre-prepared powdered glass containing SO3 through a flame heated between 1100-1500°C. Due to the increase in solubility, SO3 as well as other gases in the glass are released from the glass. During high temperatures, the glass becomes spherical because of the surface tension. The spillage gas forms hollow glass beads when it is sealed within the spherical particle.
2. Spray granulation is a method of granulation.
Spray granulation is made with aqueous sodium silicate solution containing a special auxiliary agent (boric, urea or ammonium tetraborate) and then by the nozzle into the spray drying solution, it is expected that after drying, the powder particles will shrink to a specific size.
3. Droplet method
The liquid drop technique uses the same raw material as the spray-granulation method. The raw materials used are 500 copies each of sodium silicate (M(SiO2):M (Na2O =2) and 10% ammonium aqueous solution. After evenly mixing, the hollow beads are sprayed onto the spray dryer tower.
4. Dry gel method
The alkyl sodium was added to diluted hydrochloric and decomposes with water. The gel was dried twice at 60°C and 150°C and then crushed in a ball mill. After grading was completed, dried gel powder was obtained. This was then foamed at 1280 in a vertical electric oven.
Applications

:
Hollow glass microspheres have many applications, including glass fiber reinforced products, composite foam, artificial wood, compound, atomic-ash, sound insulation and heat preservation, bowling material, low density cement, sealing materials, lightweights, resin handicrafts, wall plate sandwich layers structure of lightweight packaging material, electronic industry.
Hollow glass microspheres are also coated to provide a conductive surface. Conductive coatings optimized in thickness give spherical materials excellent shielding and conducting properties, but still maintain the weight savings of hollow low-density material. These conductive microbubbles can be used in military applications, biotechnology and medical devices as well electronics.
Hollow glass beads can reduce weight and improve sound insulation. The products are also resistant to cracking and have good reprocessing properties. It is used in the manufacture of composite materials like wood, engineering plastics, rubber, buoyancy materials, FRPs, artificial marbles, man-made stones, the oil and gas industry, aerospace and communications, new high-speed cars and ships, thermal insulation coatings and adhesives.
