A system for forming a hollow modular candle filter includes: a first filter portion having at least one open end; a hollow second filter portion having at least one open end; a sleeve configured to fit within the open end of the first filter portion and the open end of the second filter portion; and an adhesive configured to bind the sleeve to each of the first filter portion and the second filter portion.

Method and apparatus for joining together modular candle filters

Processes of forming or repairing a structure for use in high temperature applications may include intermixing a sodium nitrite (NaNO) additive with a refractory material; and applying the refractory material to a structure surface.

Single additive refractory materials suitable for multiple application methods

A refractory composition and processes for manufacture are provided where the compositions possess improved refractory alkali resistance and superior handling properties. Compositions and processes for their manufacture may include a plurality of ceramic particles and a binder sintered to the particles wherein the binder includes crystalline aluminum orthophosphate distributed as the result of an in situ reaction of aluminum metaphosphate with alumina. Kits provided according to the invention provide materials for use in manufacture of a composition where the kit includes aluminum metaphosphate and a nonfacile additive.

Refractory composition and process for forming article therefrom

Refractory compositions and methods of forming articles therefrom are provided that include a plurality of aggregate particles and a binder intermixed with the aggregate particles. The binder composition includes sintered crystalline chromium metaphosphate or chromium-aluminum metaphosphate, or combinations of the two distributed in the binder. The provided compositions are free of chromium oxide yet exhibit excellent slag resistance and are easily disposed of.

A cementitious material is provided that includes a phosphate based component and an alkali earth component. The alkali earth ion component has as a majority source a calcium aluminate calcium ion source of dodeca-calcium hepta-aluminate, or tricalcium aluminate. Magnesium oxide that has been fused and crushed to a size of less than 200 microns, alone or in combination with the calcium aluminate calcium ion source is also provided as the alkali earth ion component. When the phosphate based component and alkali earth ion components are combined in appropriate proportions, a rigid structure is obtained. A cementitious material formulation is also provided having an aqueous acidic phosphate solution as a part B and an alkali earth ion source as a part A that includes calcium aluminate, magnesium oxide or a combination thereof. Other additives include strength enhancing insoluble phosphate additive, an impurity metal reaction suppressant, tackifiers, anti-foaming agents, and the like.
