Hexoloy Kiln Support Beams

Product Application

Hexoloy SiC Kiln Support Beams offer true low mass design potential for high temperature furnace applications. The excellent strength of Hexoloy SiC allows for reduction of beam cross section by some 50% versus traditional refractory SiC materials, without compromising load carrying capability. Use of Hexoloy beams can maximize furnace productivity and reduce total firing costs.

Product Description
Hexoloy SiC is produced by pressureless sintering submicron silicon carbide powder. The sintering process results in a self-bonded, fine grained (less than 10 �m) SiC product which is 98% dense. Hexoloy SiC's outstanding high temperature properties (strength, oxidation resistance, low creep) make it an ideally suited kiln support beam material.

Comparison of Typical Beam Cross-Sections:


High Temperature Strength
Hexoloy SiC exhibits strength of 2-3x that of nitride bonded and recrystallized SiC refractory materials. Hexoloy SiC's strength is also nearly twice that of reaction bonded (SiSiC) SiC materials. More importantly, Hexoloy SiC retains its strength at temperatures exceeding 1700°C.

Oxidation Resistance
In extended duration testing in steam (1100°C), Hexoloy SiC exhibited outstanding oxidation resistance as evidenced by its extremely low weight gain compared to traditional SiC refractory materials.

Creep Resistance
Hexoloy SiC has unequaled creep resistance at elevated temperatures. In tests performed at 1600°C, Hexoloy SiC shows improvement in creep resistance of greater than 400% compared to recrystallized and nitride bonded SiC materials.


Hexoloy® SA SiC Beams for Low Mass Kiln Cars

A technically superior, cost-effective solution

Hexoloy SA SiC Beams can provide a technically superior, cost-effective solution in demanding high temperature kiln applications. They can handle much higher loads - with a lower mass - at higher temperatures for a longer period of time.


Features & Benefits
  • Reduced beam volume and weight mean more product per kiln run
  • Performs at temperatures other materials can not (>1750°C)
  • Excellent oxidation resistance translates to long beam life
  • Excellent creep resistance minimizes beam warp
  • Excellent thermal shock resistance, allows for faster cycles - heat up and cool down
  • Overall lower operating costs
