Customer Friendly, High Quality Ceramics from our Complete Ceramic manufacturing facility.

Ozark Technical Ceramics is the most diverse supplier of Magnesium Oxide (MgO) fabricated ceramic shapes in the industry. Purities are available from 99.8% to 96% MgO and products are engineered for excellent thermal, electrical, and dimensional properties. OZARK also offers a complementary line of Aluminum Oxide (Al2O3) products by all three fabrication methods, and extrusions of Hafnium Oxide (HfO2) for exotic high temperature thermocouple use.

MgO products are made by state-of-the-art techniques of slip casting, extrusion, and dry pressing. 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. Dry pressing is employed for bulk forms and occasional large shapes.

Crucibles from 99.4% MgO and 99.6% Al2O3

Our Slip Casting process is specifically developed for fabrication of MgO ware with stringent purity and microstructural requirements. Our MgO body is a 99.4% pure MgO, fine grained, high density body with a nominal 1/8" cast thickness.

Fine grained, High Density crucibles, trays and shapes.
Many convenient stock sizes from 0.5" to 6" diameter.
Suitable for processing exotic alloys, actinides, and PZTs.

Our Extruded Products are custom made to specification for dimensions, density, mechanical, and electrical properties. We service a wide range of markets from exotic thermocouple probes in the aerospace and nuclear industry to low cost heaters used in consumer products.

Crushable and hardfired in sizes .030 to 1.00 Inch
Various grades of Magnesia, Alumina and Hafnia.
Stock sizes, no tooling charges, fast track delivery.

Our Custom Ceramic products includes pressed shapes for custom electrical, refractory, and corrosive applications. We use specialized machining and R&D technologies to produce quality ceramics from MgO, Al2O3, or customer specified materials.

Limited quantity runs with reasonable tooling costs and turnaround.
