This disclosure relates to a process for preparing co-pelletized submicron pigment powder/polymer pellets in a dry drum pelletizing process using a thermoplastic polymer as seed pellets. Also disclosed is a process for using the co-pelletized product either for formation of masterbatch or for directly introducing at least one pigment into thermoplastic media.

Barium titanate based dielectric compositions having the general formula Ba. sub. (1-x-x'-x") Pb. sub. x Ca. sub. x' Sr. sub. x" Ti. sub. (1-y-y'-y") Sn. sub. y Zr. sub. y' Hf. sub. y" O. sub. 3, wherein x, x', x" and y, y', y" represent mole fractions of the divalent and tetravalent cations and x and x' have independent value greater than 0. 01 and less than 0. 3 and x", y, y' and y" have independent values greater than zero and less than 0. 3, such that the sum (x+x'+x") is greater than 0. 01 and less than 0. 4 and the sum (y+y'+y") does not exceed 0. 4. Regardless of the specific composition selected, the products of the invention have a mean primary particle size in the range of 0. 05 to 0. 4 microns with a very narrow particle size distribution. The products are dispersible so that the mean particle size determined by image anaylsis and by sedimentation are comparable.

The present invention relates to a variety of dispersible doped multi-component BaTiO. sub. 3 based powder compositions. The primary particles of each of the products are substantially spherical, have sizes in the range of 0. 05 to 0. 4 microns and have narrow size distributions. Further, the compositions of the primary particles, forming each powder, are comparable. The amount of dopant oxide or oxides contained in the powder composition ranges from between greater than 1 to 10 mole percent. Regardless of the dopant or dopants utilzied, all the powder compositions of the present invention are identified by the same unique morphological characteristics.

The present invention involves a method for producing a variety of barium titanate based powder products consisting of submicron, dispersible primary particles having narrow size distributions. The method, in its broadest aspects, involves heating an aqueous slurry of PbO, or Pb(OH). sub. 2, and Ca(OH). sub. 2 with a stoichiometric excess of the hydrous oxides of Ti(IV), Sn(IV), Zr(IV) and Hf(IV) to a temperature not exceeding 200. degree. C. Thereafter, the resulting slurry temperature is adjusted to between 50. degree. and 200. degree. C. and a solution of Ba(OH). sub. 2 and Sr(OH). sub. 2, having a temperature of 70. degree. to 100. degree. C. is added within a period of five minutes or less to the slurry. About 10 minutes after the addition of the Ba(OH). sub. 2 and Sr(OH). sub.

Solid or liquid organic materials are converted to high BTU gas with little or no undesirable char formation by reaction with water at or above the critical temperature of water and at or above the critical pressure of water to achieve the critical density of water. The reaction can be conducted either in the presence or in the absence of a catalyst.
