TRIPOLI Chemical Properties,Usage,Production

Chemical Properties

Soft, porous granules resulting from natural decomposition of siliceous rock.

Chemical Properties

Silicon dioxide/crystalline silica is a component of many mineral dusts and materials which melts to a glass at very high temperature.

Uses

Abrasive, polishing powder, filtering material, absorbent for insecticidal chemicals, paints (inert filler, wood filler), rubber filler, base for scouring soaps and powders, oil-well drilling muds.

Definition

Tripoli is an abrasive composed of a siliceous substance and used for polishing.

Potential Exposure

Cristobalite is used in the manufacture of water glass, refractories, abrasives, ceramics and enamels. Quartz is used as a mineral, natural or synthetic fiber. Tridymite is used as a filtering and insulating media and as a refractory material for furnace linings. Workers are potentially exposed to crystalline silica in such industries as granite quarrying and cutting, foundry operations; metal, coal, dentistry, painting, and nonmetallic mining; and manufacture of clay and glass products.

Incompatibilities

Violent reactions with powerful oxidizers: fluorine, chlorine trifluoride; manganese trioxide; oxygen difluoride, hydrogen peroxide, etc.; acetylene; ammonia.

Toxics Screening Level

The initial threshold screening level (ITSL) for chlordane is 3μg/m3 with an annual averaging time.

Waste Disposal

Sanitary landfill
