Abstract

Vessels selected from crucibles, pans, open cups and saggars essentially comprising of two components, from which (A) one component being a ceramic matrix composite, and (B) the second component being from metal or alloy, and wherein component (A) is the inner one.

First claim

1 : A vessel, selected from the group consisting of a crucible, a pan, an open cup and a saggar and essentially comprising two components:
(A) a ceramic matrix composite, and (B) a metal or alloy, wherein component (A) is an inner component with respect to component (B).

2 : The vessel of claim 1 , wherein the ceramic matrix composite comprises:
fibers comprising silicon carbide, silicon nitride, silicon oxynitride, carbon fiber or combinations thereof, and a ceramic matrix comprising SiC, silicon nitride, silicon oxynitride, aluminum oxide, silica, mullite, cordierite, spinel or combinations thereof.

3 : The vessel of claim 1 , wherein the ceramic matrix composite comprises:
fibers comprising aluminum oxide, mullite or combinations thereof, and a ceramic matrix comprising aluminum oxide, silica, mullite, cordierite, spinel or combinations thereof.

4 : The vessel of claim 1 , wherein component (A) has an average wall thickness in a range of from 0.5 to 5 mm.

5 : The vessel of claim 1 , wherein component (A) has a square-shaped base.

6 : The vessel of claim 1 , wherein of components (A) and (B) have different shapes.

7 : The vessel of claim 1 , wherein component (B) is made from an alloy with a thermal conductivity in a range of from 15 to 35 W/mK at 1000° C.

8 : The vessel of claim 1 , wherein component (B) is made from steel.

9 : The vessel of claim 1 , comprising an additional component (C) selected from graphite and molybdenum foils and from coatings.

10 : A process for manufacturing the vessel of claim 1 , the process comprising:
(α) providing a green body of component (A), (β) providing component (B), (γ) optionally, pre-treating the green body of component (A) by vacuum treating, compressing or drying, (δ) firing the green body of component (A) or the pre-treated green body according to (γ), if applicable, (ε) contacting component (B) either with the green body of component (A) before (γ) or with the pre-treated green body according to (γ) or with component (A) after firing.

11 : The process of claim 10 , wherein the green body of component (A) is made by arranging a fabric around a shaped body, wherein said fabric is made from ceramic fibers and soaked with a slurry of a ceramic material or its precursor.

12 : The process of claim 10 , wherein the green body of component (A) is made by winding a roving, tow, filament or yarn around a shaped body, wherein said roving, tow, filament or yarn is impregnated with a slurry of a ceramic material or its precursor.

13 : A process for making an oxide material, said process comprising:
(a) providing a mixture of at least two solid particulate materials, of which at least one is an oxide or hydroxide or carbonate, (b) moving said mixture in the vessel of claim 1 , wherein the vessel is open, through an appliance in which said mixture is subjected to a heat treatment, thereby reacting the particulate materials with each other, (c) cooling the material resulting from (b).

14 : The process of claim 13 , wherein the oxide material is a cathode active material for lithium ion batteries and is selected from the group consisting of a lithiated layered oxide, a lithiated spinel (NMO), an LiCoO 2 -coated layered nickel-cobalt-magnesium oxide and a lithiated nickel-cobalt aluminum oxide (NCA).

15 : The process of claim 13 , wherein the cooling (c) or a heating phase in (b) is performed at a rate in the range of from 1 to 50° C./min.
