Electronic ceramics are integral components of numerous devices including computers, wireless communication, automotive and industrial control systems, and digital switches. High performance refractories from Saint-Gobain are proven to withstand the extreme demands in the production of electronic components.
High purity alumina, mullite, zirconia and zirconia-coasted alumina refractories from Saint-Gobain are engineered for strength, thermal shock resistance, creep resistance, chemical compatibility, dimensional stability and minimal mass, ensuring maximum productivity and longer life.
Refractories are used in the production of:
Electronic ceramics --
|Glass, quartz and crystal|
Thin, high strength Alundum® alumina or Mullfrax® mullite setters and sandwich batts are used for firing soft ferrites (electromagnets). Sandwich batts are manufactured with a core layer of silicon carbide sandwiched between two non-reactive alumina surfaces. These batts provide improved thermal shock resistance and prolonged flatness retention. Non-reactive Zirnorite® zirconia refractories help to achieve the highest ferrite permeability values.
Zirnorite® zirconia or zirconia-coated alumina refractories are chemically compatible with titanate materials used to manufacture a variety of products including capacitors, RF filters, resistors, thermistors and piezolelectrics.
Alundex® and Alundum® alumina refractories from Saint-Gobain are designed to yield flat substrates free from defects, providing high strength and smooth setting surfaces that maintain excellent flatness retention after repeated cycles. High strength alumina and silicon carbide products provide outstanding creep resistance at high temperatures. Saint-Gobain can grind setting surfaces to 0.1% for the ultimate flatness requirements.
Zirnorite® zirconia and Alundum® alumina refractories are proven to withstand extreme operating temperatures in quartz and crystal (ruby, sapphire, yttrium aluminum garnet) processing furnaces. Their low thermal conductivity minimizes heat loss and easily reaches maximum temperature. High purity alumina and zirconia products provide excellent stability and longevity in thermally demanding operations. Low thermal conductivity is particularly valuable for minimizing heat losses and easily attaining maximum temperature.
