Bioceramic compositions

Abstract

This invention relates to compositions and applications for a bioceramic composition that includes from about 45 to about 55% by weight of kaolinite (Al2Si2O5(OH)4); from about 5 to about 15% by weight of tourmaline; from about 3 to about 13% by weight of aluminum oxide (Al2O3); from about 11 to about 19% by weight of silicon dioxide (SiO2); and from about 3 wt % to about 13 wt % zirconium oxide (ZrO2).

What is claimed is: 
     
         1 . A fabric or a textile comprising a bioceramic composition consisting of:
 a) from about 47 wt % to about 53 wt % kaolinite (Al 2 Si 2 O 5 (OH) 4 );   b) from about 5 wt % to about 15 wt % tourmaline;   c) from about 11 wt % to about 19 wt % silicon dioxide (SiO 2 );   d) from about 3 wt % to about 18 wt % aluminum oxide (Al 2 O 3 ); and   e) one additional oxide;   
       wherein the amounts are by total weight of the composition, wherein the bioceramic composition is applied or incorporated into the fabric or the textile. 
     
     
         2 . The bioceramic composition of  claim 1 , wherein the one additional oxide is zirconium oxide (ZrO 2 ). 
     
     
         3 . The bioceramic composition of  claim 2 , wherein the amount of said zirconium oxide (ZrO 2 ) is from about 3 wt % to about 13 wt % zirconium oxide (ZrO 2 ) by total weight of the composition. 
     
     
         4 . A method for manufacturing a fabric or a textile article comprising the steps of:
 (a) forming a mixture consisting of from about 47 wt % to about 53 wt % kaolinite (Al 2 Si 2 O 5 (OH) 4 ); from about 5 wt % to about 15 wt % tourmaline; from about 11 wt % to about 19 wt % silicon dioxide (SiO 2 ); from about 3 wt % to about 18 wt % of aluminum oxide (Al 2 O 3 ), and one additional oxide; and   (b) applying or incorporating the mixture into the fabric or the textile article.   
     
     
         5 . The method of  claim 4 , provided that the incorporating step comprises silk-screen printing. 
     
     
         6 . The method of  claim 4 , wherein the one additional oxide is: zirconium oxide (ZrO 2 ). 
     
     
         7 . The method of  claim 5 , provided that the one additional oxide is from about 3 wt % to about 13 wt % zirconium oxide (ZrO 2 ).
