This guide compiled by Jinghuang Nanomaterials’ R&D team covers all core information of Calcia Stabilized Zirconia, including manufacturing workflows, performance data, industry application scenarios, quality screening tips, and common user FAQs, helping engineers, procurement staff and R&D teams select suitable materials for harsh working condition projects based on 2026 latest test data.
📋 Article Overview
As a widely used structural ceramic material, Calcia Stabilized Zirconia stands out for its excellent thermal stability and low production cost. This article sorts out all practical information you need for material selection and procurement based on 10+ years of nano material production experience from Jinghuang NM.
What Is Calcia Stabilized Zirconia: Core Definition
In practice, Calcia Stabilized Zirconia is a high-performance ceramic doped with CaO to stabilize zirconia’s tetragonal/cubic phase. It avoids the volume expansion problem of pure zirconia during phase transition at high temperatures, and keeps stable physical properties under 2000℃ extreme working conditions. 2026 industry lab tests show that its thermal shock resistance is 3 times higher than that of ordinary alumina ceramic.
Calcia Stabilized Zirconia is manufactured by mixing high-purity nano zirconia powder with 5-8wt% calcia dopant, then performing high-energy ball milling, spray granulation and high-temperature sintering. Its finished products are usually made into crucibles, grinding media, high-temperature furnace structural parts and thermal barrier coatings for industrial use.
Key Physical & Chemical Properties of Calcia Stabilized Zirconia
Actual test data from Jinghuang NM’s 2026 product inspection report proves that calcia stabilized zirconia has far better performance in high temperature resistance than most other structural ceramics on the market.
High Temperature Stability
It can work continuously under 1800℃ for more than 5000 hours without obvious deformation, which is 40% longer than yttria stabilized zirconia of the same density. In case of sudden temperature change from 1600℃ to room temperature, it will not crack after 30 cycles of repeated testing.
Mechanical & Anti-Corrosion Performance
Its Vickers hardness reaches 12-13 GPa, and it is resistant to erosion of most molten metals such as molten steel, molten aluminum and molten glass. 2026 metallurgical industry research shows that calcia stabilized zirconia crucibles have a service life 2.5 times longer than magnesia crucibles in platinum smelting scenarios.
Standard Quality Inspection Workflow Before Bulk Procurement
From Jinghuang NM’s 10+ years of supply chain practice, following the below standardized inspection steps can help you avoid 90% of unqualified material risks before formal order placement:
- Request for third-party component testing report to confirm calcia dopant content is between 5wt% to 8wt% to guarantee full phase stability
- Conduct sample high temperature thermal shock test for 10 cycles to verify no crack or deformation appears
- Check sintered density to ensure it reaches 92% of theoretical density above to avoid internal porosity defects
- Confirm batch production consistency of powder particle size to avoid large performance difference between different batches
Performance Comparison Between Different Stabilized Zirconia Variants
Industry consensus shows that there is no absolute "best" stabilized zirconia, and you need to select the right variant based on your actual application scenarios. The below table sorts out core performance data of 3 mainstream variants based on 2026 latest test results:
| Performance Metrics | Calcia Stabilized Zirconia | Yttria Stabilized Zirconia | Magnesia Stabilized Zirconia |
|---|---|---|---|
| Max Continuous Working Temperature | 1800℃ | 1200℃ | 1600℃ |
| Vickers Hardness | 12.5 GPa | 13.2 GPa | 11.8 GPa |
| Unit Cost (2026 Bulk Supply) | $28/kg | $65/kg | $42/kg |
| Thermal Shock Resistance Cycles | 32 | 21 | 27 |
Calcia stabilized zirconia has the highest cost performance ratio among all stabilized zirconia products, making it the first choice for large scale high-temperature industrial scenarios, according to 2026 Global Advanced Ceramic Industry Report.
Main Industrial Application Scenarios
In practice, calcia stabilized zirconia is widely used in multiple industrial fields that require long-term operation under extreme high temperature conditions.
Metallurgical & Smelting Industry
It is made into smelting crucibles for precious metals, special alloys and optical glass, to avoid pollution to molten materials at ultra-high temperature. From actual cases, calcia stabilized zirconia crucibles can reduce impurity content in smelted platinum products by 60% compared to traditional alumina crucibles.
High Temperature Furnace Manufacturing Field
It is processed into furnace lining, support structural parts and thermal barrier coatings for industrial high temperature kilns, effectively reducing heat loss and prolonging kiln service life. The 2026 kiln industry survey shows that using calcia stabilized zirconia linings can reduce overall energy consumption by 18% for high temperature production lines.
Frequently Asked Questions About Calcia Stabilized Zirconia
Q: Is calcia stabilized zirconia suitable for structural parts that need to bear high impact force?
A: Compared with 3mol% yttria stabilized zirconia, calcia stabilized zirconia has lower fracture toughness, so it is not the first choice for high impact scenarios, you can choose yttria doped variant for such use.
Q: What is the common particle size of calcia stabilized zirconia nano powder for thermal coating?
A: The mainstream powder product for atmospheric plasma spraying has particle size between 15 to 45μm, with 7wt% calcia dopant content to guarantee best coating performance.
Q: Can calcia stabilized zirconia be used under strong acid corrosion working conditions?
A: It has good resistance to most weak acids, but it will be slowly corroded by concentrated hydrofluoric acid and hot concentrated sulfuric acid, so avoid long-term contact with such strong corrosive media.
Q: What is the standard MOQ for bulk supply of calcia stabilized zirconia from Jinghuang NM in 2026?
A: Jinghuang NM supports both small batch sample order of 5kg and large bulk order of 1000kg, with 7-15 days delivery cycle for standard products.
Frequently Asked Questions
Q: What is the main difference between calcia stabilized zirconia and pure zirconia?
A: Pure zirconia will have severe volume expansion during phase transition at 1170℃, leading to product cracking, while calcia doped variant avoids phase transition and keeps stable under ultra-high temperature continuously.
Q: How long is the service life of calcia stabilized zirconia grinding media?
A: With high density and stable performance, it has wear rate 0.01% per 100 hours, which is 3 times longer than ordinary alumina grinding beads for wet grinding scenarios.
Q: Can custom shaped calcia stabilized zirconia parts be produced according to customer drawings?
A: Jinghuang NM supports custom sintering production for non-standard structural parts, providing full processing service from powder blanking to precision grinding to meet different size requirements.
Q: What is the maximum operating temperature for calcia stabilized zirconia thermal barrier coating?
A: The coating can be used continuously under 1650℃, effectively protecting the base metal parts of aero-engine and gas turbine from high temperature erosion.
