PCT No. PCT/SE85/00217 Sec. 371 Date Jan. 8, 1986 Sec. 102(e) Date Jan. 8, 1986 PCT Filed May 23, 1985 PCT Pub. No. WO85/05352 PCT Pub. Date Dec. 5, 1985.The invention resides in a process of preparing an inhomogeneous sintered body by adjoining metal powder with refractory ceramic powder at normal powder metallurgical pressures and sintering conditions. The invention is characterized thereby that the sintered body is manufactured in one layer or several layers having displaced mixing ratio between the ceramics and the metal and that the binding between ceramics and metal is strengthened with monoaluminium phosphate or a monoaluminium phosphate former. The sintered body can be used for example as heat shielding.
