摘要： Process for manufacturing a product, comprising the following successive steps: a) mixing raw materials to form a starting feedstock, b) melting the starting feedstock so as to form a molten liquid, c) solidifying the molten liquid so as to obtain a fused product comprising crystals linked by a glassy phase, and d) crystallization heat treatment of the glassy phase of said fused product, in which the composition of the starting feedstock is adapted in order to manufacture a product having the following chemical composition, as weight percentages based on the oxides, and for a total of 100%: 40% ≤ (ZrO
2 + HfO
2 ) ≤ 94%, 6% 2 2 O
3 , 0% ≤ Al
2 O
3 , 2% ≤ SiO
2 , 0% ≤ MgO, 0% ≤ TiO
2 , and other oxides ≤ 1%. Use of the product obtained as a grinding agent, an agent for dispersing in a wet medium, a surface treatment agent, a supporting agent or a heat-exchange agent.

摘要： The invention relates to a sintered particle having a chemical analysis, in weight percent, of: ZrO
2 partially stabilized with CeO
2 and Y
2 O
3 : the remainder up to 100%; Al
2 O
3 : 10-60%; additive selected from CaO, a manganese oxide, La
2 O
3 , SrO, BaO, and the mixtures thereof: 0.2-6%, the CaO content being lower than 2%; impurities: 2 and Y
2 O
3 , present with a molar content in molar percent on the basis of the sum of ZrO
2 , CeO
2 and Y
2 O
3 , of: CeO
2 : 6-11 mol %; and Y
2 O
3 : 0.5-2 mol %, the particle being produced by sintering at a sintering temperature higher than 1300°C, the sintering temperature being lower than 1400°C if the additive is CaO or if the CeO
2 molar content is between 10 and 11%.
