An opaque silica comprises silica and at least one second phase solid material. The at least one second phase solid material is essentially uniformly dispersed in the silica. A cut surface formed through the silica is free from surface defects since the at least one second phase solid material forms an opaque silica that is free from porosity.

Opaque silica composition

An electrolyte structure is produced by forming matrix material powder into a blank at room temperature and impregnating the resulting matrix blank with molten electrolyte.

Process of making electrolyte structure for molten carbonate fuel cells

A particulate mixture of an alkali chloride solvent salt, a lithium salt reactant selected from the group consisting of lithium hydroxide, lithium nitrate, lithium carbonate and mixtures thereof, and an aluminum salt reactant selected from the group consisting of aluminum hydroxide, alpha-alumina, gamma-alumina and mixtures thereof is heated to melt the chloride salt solvent in which the lithium and aluminum salt reactants dissolve and react precipitating lithium meta-aluminate.

Molten salt synthesis of lithium meta-aluminate powder

A relatively thin coat of calcium metaborate is electrolytically-applied from a solution of calcium formate with boric acid directly to the surface of a boron-containing electrical steel and a substantially thicker overcoat of Mg(OH).sub.2 is electrolytically-deposited on the calcium metaborate coating to provide a duplex coating about 0.2 mil thick.

Coated silicon-iron product and process therefor using calcium formate

A boron-containing electrical steel sheet is provided with an electrolytically-deposited boron-containing Mg(OH).sub.2 primary coating about 0.05 mil thick and a secondary coating of electrolytically-deposited Mg(OH).sub.2 about 0.15 mil thick. Magnesium formate is employed as the water-soluble magnesium salt in preparing the electrolytes.

Coated silicon-iron product and process therefor using magnesium formate

A boron-containing magnesium hydroxide coating is electrolytically applied to a boron-containing electrical steel through the use of an electrolyte at 90.degree. C. which is an aqueous solution of magnesium formate and magnesium metaborate containing magnesia as a solid second phase and having a pH in the range from 8.0 to 9.0.
