• White fused alumina is used for its hardness and strength. It is widely used as an abrasive, including as a much less expensive substitute for industrial diamond.
  • White aluminum oxide flakes are base material for effect pigments. These pigments are widely used for decorative applications. For example in the automotive or cosmetic industry.
  • White aluminum oxide is also used in preparation of coating suspensions in compact fluorescent lamps.
  • White fused alumina is an electrical insulator used as a substrate(silicon on sapphire)for integrated circuits but also as a tunnel barrier for the fabrication of superconducting devices such as single electron transistors and superconducting quantum interference(squid)devices.
  • It is also used to make spark plug insulators.


As an eco-friendly sandblasting material, brown fused alumina is widely used in aluminium profile, precision mould etc.

As an advanced abrasive material, it is common to see in grinding kinescope, optical glass, monocrystalline silicon, lens, crystal glass etc. Good for manufacturing resin abrasive tool.

Ideal filler for automobile brake, special tire, highway pavement, airstrip etc.
It is also a suitable filter medium, waterjet cutting material and refractory.


Garnet sand is a good abrasive, and a common replacement for silica sand in sand blasting.
Mixed with very high pressure water, garnet is used to cut steel and other materials in water jets.
Garnet paper is favored by cabinetmakers for finishing bare wood.
Garnet sand is also used for water filtration media.


It is used for its hardness in abrasive machining processes such as grinding, honing, water-jet cutting and sandblasting. Particles of silicon carbide are laminated to paper to create sandpapers and the grip tape on skateboards.

Like other hard ceramics, silicon carbide is used in composite armor , and in ceramic plates in bulletproof vests.
Silicon carbide is used as a support and shelving material in high temperature kilns such as for firing ceramics, glass fusing, or glass casting.

Silicon-infiltrated carbon-carbon composite is used for high performance “ceramic” brake discs, as it is able to withstand extreme temperatures.

Silicon carbide fibers are used to measure gas temperatures in an optical technique called thin filament pyrometry.


Specially prepared fused silica is the key starting material used to make optical fiber for telecommunications.
Because of its strength and high melting point (compared to ordinary glass), fused silica is used as an envelope for halogen lamps.

The combination of strength, thermal stability, and UV transparency makes it an excellent substrate for projection masks for photolithography.

Due to the thermal stability and composition it is used in semiconductor fabrication furnaces.
Fused silica has nearly ideal properties for fabricating first surface mirrors such as those used in telescopes.
Fused silica as an industrial raw material is used to make various refractory shapes such as crucibles, trays, shrouds, and rollers for many high-temperature thermal processes including steelmaking, investment casting, and glass manufacture


Owing to its high thermal and chemical stability and abundance, quartz is widely used in many large-scale applications related to abrasives, foundry materials, ceramics, and cements.
Silica sand is the principal component in common glass.
Graded silica sand serves as an abrasive in cleaning, preparing, and polishing.
Media filters use silica sand for filtering water.
Mixing silica sand with paint produces a textured finish for walls and ceilings or non-slip floor surfaces.
