CLAY-PHOSPHATE MATERIAL Russian patent published in 2009 - IPC C04B33/132 

FIELD: chemistry.

SUBSTANCE: clay-phospate material contains Cambrian blue clay, iron- containing waste of metallurgical production based on Fe(II) oxide with residue on sieve №008 5-7%, orthophosphoric acid with density 1.25 g/cm³ and crashed glass empties with resisdue on sieve №008 5-7%, wt %: SiO₂ - 62.00; Al₂O₃ - 4.00; B₂O₃ - 7.00; CaO - 10.00; MgO - 2.00; Na₂O - 15.00, with following components ratio, wt %: Cambrian blue clay - 57-58; said waste - 8-10; said crashed glass empties - 15-16; orthophosphoric acid with density 1.25 g/cm³ - the remaining part.

EFFECT: reduction of heat conductivity coefficient of clay-phosphate material.
