calcium oxide
CALFUSE®
Electro-Fused Calcium Oxide
Calcium oxide with slake-resistance improved by means of the electro-fused method.
Features
Using its unique electro-fused technology, we have succeeded in producing the CALFUSE® compact, high-purity calcium oxide by inducing lime crystal grain growth.
CALFUSE® therefore has excellent slake-resistance. In addition, it has greater thermal shock resistance than that of magnesium oxide, enabling use of our calcium oxide in long-life refractory lining and similar materials.
Recently, crucibles made from electro-fused calcium oxide are used to melt special metals, such as titanium alloy, in order to remove impurities.
Slake - resistant calcium oxide
1. Composed of compact and homogeneous crystals, it has high slake resistance.
2. It is a high-purity product.
3. It has an impurity-removing flux effect.
4. It has an impurity-removing flux effect.
Usages
• Raw material for steel-making refractories
• Raw material for metal-melting crucibles
• Flux material for ESR furnaces
• Floor powder used in sintering electronic parts
