Abstract

A novel metal/ceramic hybrid material in which the void space of the ceramic is filled with metal. The metal may be bonded to the ceramic, for example by formation of a metal oxide. The metal may be introduced into the ceramic as small particles in a suspension then heated to melt the metal, allowing bonding to the ceramic or better filling of the void space. The hybrid material may be used in a variety of applications.

Claims

exact text as granted — not AI-modified
1 . A hybrid material comprising: 
 a ceramic with void space; and    a metal;    wherein the metal is covalently bonded to the ceramic such that a percentage of the void space remains void; and    wherein the ceramic comprises approximately 100% silica.    
     
     
         2 - 3 . (canceled)  
     
     
         4 . The hybrid material of  claim 1 , wherein the ceramic comprises up to 50% cristobalite.  
     
     
         5 . A hybrid material comprising: 
 a ceramic with void space; and    a metal;    wherein the metal is covalently bonded to the ceramic such that a percentage of the void space remains void; and    wherein the ceramic comprises up to 60% alumina.    
     
     
         6 . The hybrid material of  claim 1 , wherein the metal is selected from the group consisting of: Mg, Ca, Sc, Ti, Cr, Mn, Fe, Co, Ni, Cu, Zn, Pd, Ag, Cd, Pt, Au, any ionic forms thereof, and any combinations thereof.  
     
     
         7 . The hybrid material of  claim 1 , wherein the metal is an alloy.  
     
     
         8 . The hybrid material of  claim 1 , wherein at least 50% of the void space is occupied by the metal.  
     
     
         9 . The hybrid material of  claim 1 , wherein at least 80% of the void space is occupied by the metal.  
     
     
         10 . The hybrid material of  claim 1 , wherein at least 95% of the void space is occupied by the metal.  
     
     
         11 . The hybrid material of  claim 1 , wherein the metal comprises at least 50% of the hybrid material by weight.  
     
     
         12 . The material of  claim 1 , wherein at least 98% of the void space is filled with the metal.  
     
     
         13 . The hybrid material of  claim 1 , wherein the metal comprises at least 50% of the hybrid material by volume.  
     
     
         14 .- 36 . (canceled)  
     
     
         37 . The hybrid material of  claim 5 , wherein the ceramic comprises up to 50% cristobalite.  
     
     
         38 . The hybrid material of  claim 5 , wherein the metal is selected from the group consisting of: Mg, Ca, Sc, Ti, Cr, Mn, Fe, Co, Ni, Cu, Zn, Pd, Ag, Cd, Pt, Au, any ionic forms thereof, and any combinations thereof.  
     
     
         39 . The hybrid material of  claim 5 , wherein the metal is an alloy.  
     
     
         40 . The hybrid material of  claim 5 , wherein at least 50% of the void space is occupied by the metal.  
     
     
         41 . The hybrid material of  claim 5 , wherein at least 80% of the void space is occupied by the metal.  
     
     
         42 . The hybrid material of  claim 5 , wherein at least 95% of the void space is occupied by the metal.  
     
     
         43 . The hybrid material of  claim 5 , wherein the metal comprises at least 50% of the hybrid material by weight.  
     
     
         44 . The material of  claim 5 , wherein at least 98% of the void space is filled with the metal.  
     
     
         45 . The hybrid material of  claim 5 , wherein the metal comprises at least 50% of the hybrid material by volume.
