6 FAQs about Inverters & Power System Solutions

Does sodium-potassium silicate glass have a mixed alkali effect?

A novel topological analysis using persistent homology found that sodium-potassium silicate glass shows a significant reduction in large cavities as a result of the mixed alkali effect. Furthermore, a highly correlated pair arrangement between sodium and potassium ions around non-bridging oxygen atoms was identified.

Why are alkaline oxides added to glass?

Alkaline and alkaline earth oxides are added to the glass in order to increase the melting rate, to decrease the viscosity of the molten glass and to obtain a good processing performance during forming. The alkali oxides are effective in improving the fusibility (“fluxing agent”)

How are alkali silicate glasses prepared?

Alkali silicate glasses were prepared from mixtures of reagent grade SiO 2, Na 2 CO 3, and K 2 CO 3 powders. The mixtures were melted at 1923 K in air. Each melt was quenched and annealed at the glass transition temperature and then cooled slowly by 1 K/min. The nominal and analyzed compositions of the glasses are listed in Table S1.

What happens if alkali ions enter SIO 2 glass?

It is possible to infer that the introduction of alkali ions into SiO 2 glass causes partial cleavage of the tetrahedron network, and thus, the numbers of non-bridging oxygen (NBO) and silicon with Q n (n < 4) (where n is the number of bridging oxygen atoms in a SiO 4 tetrahedron) 8 increase by breaking the silicon–oxygen bonds.

Does display cover glass have a robust alkali-resistance of UV-shielding and strengthening sol-gel coating?

In this report, robust alkali-resistance of display cover glass's UV-shielding and strengthening sol-gel coatings have been successfully prepared, using 2,2′,4,4′-tetrahydroxybenzophenone (BP-2), γ- (2,3-epoxypropoxy) propyltrimethoxysilane (KH560) and tetraethyl orthosilicate (TEOS) as raw materials.

How to make a cover glass a strong alkali-resistant coating?

Robust alkali-resistant is obtained by tailoring an organic UV absorbent bonded to SiO 2 sol-gel. The new and facile preparation of the coating presents its application possibility on cover glass. Cover glass with UV-shielding function is important to mobile displays such as mobile phones and tablet PCs, as well as flexible photovoltaic cells.
