钙稳定氧化锆-定径水口耐火材料
钙稳定氧化锆空心球、颗粒和粉末是锆基定型耐火材料的优质原料。它是一种经过氧化钙 (CaO) 化学稳定的电熔氧化锆。钙稳定氧化锆在高温下能够保持其立方晶体结构。因此，其热性能更佳，尤其具有高抗腐蚀性和抗热震性。它可以防止定型耐火材料开裂。
Calcia-Stabilized Zirconia grain is a superior raw material for zirconium base shaped refractories. It is a type of fused zirconia that has been chemically stabilized with calcium oxide (CaO). Calcia stabilized zirconia can maintain its cubic crystal structure at high temperature. Thus the thermal performance is better especially with high anti-corrosion, and thermal shock resistance. It can avoid the shaped refractories cracking.
特性：
1. 高熔点（约2700°C）。
2. 良好的抗热震性。
3. 中等离子电导率。
4. 化学惰性和耐腐蚀性。
5. 与钇稳定氧化锆相比，成本效益更高。
Properties:
1. High melting point (~2700°C).
2. Good thermal shock resistance.
3. Moderate ionic conductivity.
4. Chemical inertness & corrosion resistance.
5. High cost effective compared to Yttrium stabilized zirconia.
