It is manufactured ion form of shapeless pieces with size up to 150 mm. The transportation is effected in bulk without packing in soft disposable containers (Big-Bag type) made from polyethylene fabric. Minimum railway lot is 60 t open wagon.
It is used in:
- manufacturing of liquid glass (water solution of block silicate) according to GOST 13078-81;
- machine-building: binding material for manufacturing of rods and forms of welding electrodes;
- paper industry: for the impregnation of paper pulp, as glue for cardboard, corrugated tare;
- in chemistry and petrol chemistry: in manufacturing of synthetic cleaning agents, silicate paints, catalysts for oil cracking, white carbon, silicagel, anticorrosion primes;
- in light industry: as a impregnation and fixative agent for bleaching and dyeing of fabrics;
- and also for the manufacturing of pastes, casting, flotation.
Physical-chemical indexes
- soda natrium silicate ГОСТ 13079-93;
- potassium-sodium and sodium-potassium silicates that are used for the manufacturing of welding electrodes TU U 21.140-97.
