Product Description
Fused silica sand high silica content 100 mesh -1500 mesh crucible grade
Quartz sand filter material is made of natural quartz ore through crushing,washing,selecting and other processes.It is the most widely used water purification material in the water treatment industry.This product is made of high-quality natural quartz stone,which is refined through the process of selection-crushing-screening-dust removal.Our products have the advantages of uniform particles,complete models and high whiteness.
This product can be used alone or in combination with anthracite filter media,which is a double-layer filter quartz sand filter media.
I. Characteristics

Application
Glass Industry Used for Architectural glass, daily-use glass, technical glass, etc., as the main raw materials of the glass industry, its quality requirements are mainly reflected in three aspects: chemical composition, stability, and particle size composition.
Mechanical Engineering Modeling sand and abrasive materials: Generally, the content of silicon dioxide should be greater than 97% for cast steel sand; for cast iron sand should be greater than 85%; for non-ferrous alloy casting sand, it should be greater than 75%
Electronics Industry High-purity metal silicon, fused silicon powder for electronic plastic packaging, optical fiber, etc.
Metallurgical Industry Used as smelting additive, flux and various ferrosilicon alloys.
Refractory High silica brick for kiln, ordinary brick and refractory powder, etc.
Cement Industry Sand cement ingredients, aerated concrete, ordinary products, etc.
Chemical Industry Production of water glass and amorphous silica, silica gel, desiccant, petroleum refining catalyst, etc. Filling Field Rubber, plastic filler, anti-corrosion and abrasion resistance, road sign coating filler, etc.
