Microspheres maintain a uniform gap between the two glass panels used to form a flat panel display(such as the LCD). Our silicon dioxide spacer is the next-generation highly functional particles which are synthesized from high purity materials that is used in electronic materials.

General Characteristics
Microsphere Composition:	Silicon Dioxide, amorphous
Nominal Diameter: Density:	4µm, 5µm, 6µm, 7µm, 8µm, 9µm 1.9 - 2.3 g/cm3
Surface Conditions:	Nonporous, Silanol group

 

Features :
1. Truly spherical, non-agglomerate, particle size is monodispersed.
2. Impurities are very few, no elution of alkaline ions; Uranium, thorium and other
radioactive elements are less than 0.1 ppb.
3. The surface is rich in silanols (≡Si-OH), assuring excellent reaction with silane and
titamate coupling agents. It is also possible to bond functional molecules via surface OH groups as a carrier for synthesizing complex particles. 4．The product is thermally stable. Weight reduction is hardly observed in the temperature range from 200 to 800 ℃. Especially suited for use in epoxy seals that require high curing temperatures.
