What are most common cyclic meta silicates?

(1) Number of oxygen atoms shared per tetrahedron is 2(Two).

(2) Total number of shared oxygen towards one Si atom is one (1)

(3) In cyclic silicates each tetrahedron shares its two oxygen atoms with other tetrahedron atom such that a cyclo silicates is formed.

(4) General formula is (Si_nO_2n)^-2n where n =3, 4,5,6,7 etc 

(5)The most common cyclic polysilicates are the cyclic trimers, (SiO₃)₃^6- and the cyclic hexamers (SiO₃)₆^12-.

(6) The most common cyclic trimer is Benitoite [BaTi(Si₃O₉)] and Wollasponite           [Ca₃(Si₃O₉)] 

(7) The most common cyclic hexamer is found in the mineral Beryl [Be₃Al₂(Si₃O₉)₂] or Be₃Al₂(Si₆O₁₈).

What is structure of solid Ortho Boric acid ?

Boric acid mainly exist in polymeric form like tri ,tetra, panta but tri and tetra meta boric acid are well known, because it's sodium salt (sodium borate,or sodium tetra borate or disodium tetra borate) is very famous which is called "Borax" or Tincal and commercially named as Jeweller,s of Borax [Na₂B₄O₅(OH)₄•8H₂0 or Na₂B₄O₇•10H₂O]

In solid state Boric [B(OH₎₃] unit are hydrogen bonded together into two dimensional sheet.

Borax is uses in manufacturing of ENAMELS and glazes for pottery and disinfectant in medicine.
