Dense Magnesium Oxide Ceramics Description
Dense Magnesium Oxide Ceramics are used as a refractory under severe conditions because their melting point (3098K) is the highest in the oxide. Magnesium Oxide is superior in corrosion resistance in molten metal. Magnesium Oxide Ceramics can be used for a lot of metals compared with Aluminum Oxide Ceramics.

Dense Magnesium Oxide Ceramics FAQs
Q1. What is Dense Magnesium Oxide (MgO) Ceramic?
Dense Magnesium Oxide (MgO) ceramic is a highly durable and thermally stable ceramic material composed primarily of magnesium oxide. It is known for its high density, hardness, and resistance to chemical attack, making it suitable for a variety of industrial applications.
Q2: Are there any limitations or considerations when using Dense MgO Ceramic?
Brittleness: Like most ceramics, MgO ceramics can be brittle and may fracture under mechanical stress or impact.
Processing Difficulty: Machining and forming dense MgO ceramics can be challenging due to their hardness and brittleness.
Cost: High-purity dense MgO ceramics can be relatively expensive due to the costs associated with raw materials and processing.
Q3. How should Dense MgO Ceramic be handled and stored?
Handling: Handle with care to avoid mechanical damage due to brittleness. Use appropriate personal protective equipment (PPE) when handling to avoid inhalation of dust or contact with skin.
Storage: Store in a dry, cool environment to prevent moisture absorption, which can affect the material's properties.
