Hi - Tone Magnesiya Private Limited Ahmedabad, Gujarat

We are offering Ceramic Media

  Porcelain is more readily formed into larger shapes Porcelain is very easy to glaze and is used extensively as insulators for overhead power transmission lines  Porcelain is easily formed by Wet Pressing, where as Steatite is not  

  Steatite is mainly used to manufacture Electrical Insulators   Steatite is magnesium silicate   Steatite has good Mechanical Strength   High volume resistively up to 1000 degree C   Good dielectric strength   Low dissipation factor     Impervious material structure   Steatite is commonly used in appliance thermostats where a high temperature electrical insulator is needed that will hold its shape and size and will not wear out during the life of the device. Steatite works very well in cold switching applications. Steatite is used to support heating elements in electric heaters, toasters, and ovens. Steatite is a good high voltage insulator. It holds up under thousands of volts without breaking down. Steatite ceramic parts are usually small and are formed from dry powder in a compaction press. The parts are then fired in the kiln. Diamond abrasives are used to grind parts to size for high tolerance applications.

Cordierite is a ceramic used in heat shock applications that would crack and shatter most other ceramic materials . Kiln furniture is made of cordierite because it will survive thousands of heating and cooling cycles. At Paratech all of our production is placed in cordierite trays known as saggers to be used in the kiln during the firing cycle.   Cordierites have excellent resistance to heat shock, due to their low coefficients of thermal expansion. Cordierites come in a range of thermal expansions, mechanical strengths and porosity's Cordierite ceramics make cost-effective insulators wether dry-pressed or extruded At K.C. Industries we make both a Dense Cordierite and a Cordierite with high porosity Cordierite that we call, Cordierite Refractory   Small cordierite parts can be dry powder pressed. Large cordierite pieces are formed by slip casting. Slip casting is a process where the ceramic material is mixed with water and poured into a plaster mold. After a few hours the plaster draws off the water from the mix and the sagger or other shape can be released from the mold. Parts are then dried and fired.

  Alumina is the most versatile engineered ceramic because of its high temperature service limit along with its chemical, electrical and mechanical properties. It is also relatively low cost, is easily formed and finished using a number of fabrication methods including injection molding for low cost, high volume production runs. It is often compounded with silica or trace elements to enhance its properties or fabrication and commonly will range from 92% to 99.8% Al2O3. Higher purity, gel cast material can be found under our REPTON brand. Alumina engineered ceramic parts can be formed by single axis pressing, isostatic pressing, injection molding, slip casting, or extrusion. Parts can "green machined" to near net size before firing and then "hard" ground using diamond tooling to tolerances less than 0.0002" (0.005 mm). Special grades of alumina can be metallized and/or brazed to metal parts
