These glass beads are the substitute of sand or rice in Incense Burner.
The incense can be easily put in Incense Glass Beads. Also the beads are unbreakable and used permanently because they don’t absorb moisture like rice and sand.
The best benefit of Incense Glass Beads is that they are helpful for health because they emit the ultrared rays at a certain temperature degree.
The use of Incense Glass Beads can also be made for crystal vases with artificial flowers in a Buddhist Sanctum. Incense Glass Beads make Sanctum more elegant and dignified.

The high-performance hollow glass microspheres, a kind of ultra-light inorganic non-metallic powder with hollow “ball-bearing” shapes, have been developed into a new type of high performance lightweight material and have been widely applied in recent years. It will be the main direction for new-type compound materials in the 21st century. Its true density is 0.20-0.60 g/cm3; particle size is 2-130μm; It owns the features with light weight, bulk density, lower thermal conductivity, higher compressive strength, improved dispersion and liquidity, and excellent chemical stability.

Application:

thermal insulation coating,putty,plastic casting polyester,FRP,SMC,BMC,radome,synthetic foam,adhesives,printed circuit board substrate,RTM,bowling,fan blades,emulsion explosives,pipeline insulation materials,artificial marble,PVC,low density oil drilling,light cement,and deep-sea buoy etc.

With the advantages of smooth surface, even size, high hardness, wearable and stable, widely used as disperser, grinding media and filler materials in day, paint, ink and chemical industry.

Weight reduction filler Hollow Glass Microspheres   is a tiny sphere with high ball-type rate. Its ball-bearing effect can improve its mobility and reduce the viscosity and internal stress of resin mixture. Therefore, during processing, less heat is produced in composite materials so as to prevent inadequate lubrication and partial thermal decomposition. It is more likely to extrude when molding, which can not only reduce defects in products, but also improve the production efficiency by 15% -20%.

Bioactive glass is a promising osteoconductive silica-based biomaterial for guidance of new bone growth. On the basis of several in vitro studies, the material appears able to promote osteoblast functions. In our in vivo study, the osteopromotive effect of bioactive glass microspheres seemed to surpass the osteoinductive action of direct adenovirus-mediated human bone morphogenetic protein 2 (BMP-2) gene transfer in a noncritical size bone defect model. The current study was initiated to elucidate the molecular mechanism behind bioactive glass action with or without adjunct BMP-2 gene transfer. A standardized bone defect of the rat tibia was filled with bioactive glass microspheres and injected with adenovirus carrying the human BMP-2 gene (RAdBMP-2). Control defects were left empty or filled with bioactive glass microspheres with injection of adenovirus carrying the lacZ reporter gene or saline. Quantitative polymerase chain reaction confirmed the expression of the transferred human BMP-2 gene at the defect area at 4 days, but not in intact reference tissues. Bone matrix components (collagens I, II, and III, osteocalcin, osteonectin, and osteopontin) and resorption markers (cathepsin K and MMP-9), determined by Northern analysis, showed a completely different pattern of gene expression in defects filled with bioactive glass compared with control defects left to heal without filling. Bioactive glass induced a long-lasting production of bone matrix with concurrent upregulation of osteoclastic markers, a sign of high bone turnover. Combining RAdBMP-2 gene transfer with bioactive glass decelerated the high turnover, but did not influence the balance of synthesis and resorption. This molecular analysis confirmed not only the highly osteopromotive effect of bioactive glass microspheres, but also the accelerated rate of new bone resorption on its surface. At least in noncritical size defects this impact of bioactive glass seems to saturate new bone formation on its surface and thereby overshadow the effect of BMP-2 gene transfer.
