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.
Crucibles from 99.4% MgO and 99.6% Al2O3
- Standard Purity MgO Ceramics
- High Purity MgO Ceramics
- Extrusions For Specialties
- Crucibles & Slip Cast Items
Cartridge heater component examples
INTRO: TATEHO OZARK did not enter the commercial MgO heater market until 1997. The previous 15 years of experience were limited to high purity MgO powders with a minimum 99.4% MgO content. This limited our ability to address the high performance cartridge heater market. The commercial market can not support the raw material costs, and many electrical and mechanical properties are improved with the ability to have beneficial silica, alumina, and lime content.
The vertical integration of the TATEHO OZARK extruded product family into heater and electrical grades has occurred very systematically. This makes TATEHO OZARK unique as the only company with total MgO capabilities in casting, extrusion, and pressing at all Purities and densities. In 2015 – Tateho Chemical Industries acquired OZARK and establishes TATEHO OZARK Technical Ceramics (TOTC)! Our relationship with our sister company (TateCera) in Une, Japan where highest quality MgO powders are produced and manufactured into Ceramics keeps our future MgO supply prospects secure. TATEHO is synonymous with high quality fused MgO for over 50 years. OZARK had a pipeline to them as a favored customer since inception. We now have the ability to create more designer blends because of our new ability to work directly with the excellent Engineers, Scientists, and Technicians at TATEHO.
TATEHO OZARK has learned a lot from our technical interactions with our excellent customers and are able to communicate about important issues regarding the form, fit, and function. Please explore our various product descriptions, with the understanding that not all technical labels and jargon are universal, and our categorizations may be inaccurate or incomplete.
