Customer Friendly, High Quality Ceramics from our Complete Ceramic manufacturing facility.
TATEHO OZARK Technical Ceramics is the most diverse supplier of Magnesium Oxide (MgO) fabricated ceramic shapes in the industry. Purities are available from 96% to 99.4% MgO and products are engineered for excellent thermal, electrical, and dimensional properties.
Our MgO products are made by two fabrication methods:
- Slip casting is the preferred fabrication method for thin walled MgO components, especially crucible shapes.
- Extrusion is used for mass production of precision tubes and shapes for thermocouple and heater components.
TATEHO OZARK also offers a complementary line of Aluminum Oxide (Al2O3) products by all three techniques, and extrusions of Hafnium Oxide (HfO2) for ultra-high temperature use.
