Are there materials that are both heat-resistant and insulating?
Thread Content
Are there any materials that are both heat-resistant and insulating, capable of withstanding temperatures ranging from 20 degrees to 1200 degrees, at a voltage of 12 kilovolts, with minimal shrinkage?
Ceramic, corundum :lol ;P
However, the processing of ceramics and corundum is too demanding and they are fragile
This material must be able to withstand radiation at 1200 degrees Celsius, as well as bearing a weight of 200 kg. The high temperature is generated by electricity (that is, through electric heating). I have tried ceramic and quartz, but quartz is fragile and cannot bear weight; ceramic is also fragile
Does anyone have any good materials? This post was last edited by yutr on 2009-2-18 at 15:56.]

Refractory materials; among silicon-aluminum products, there are high-load variants that can meet your requirements
You can look into silicon nitride ceramics or their composite materials!
Refer to this: High-temperature adhesive, Model: ZT-II. Aliases: High-temperature bonding agent, High-temperature adhesive substance. Properties: A colorless to slightly yellowish viscous liquid that is soluble in water, has a weakly acidic nature, and does not contain sodium ions. Purpose: Suitable for bonding under high-temperature conditions of over 300°C, especially for the construction or repair of high-temperature furnaces. Such as bonding ceramics and similar materials, constructing and repairing various high-temperature furnaces and heat treatment ovens, spray materials for the periodic renovation of furnaces, and bonding aluminum silicate refractory fibers, etc. Primary uses: 1. Used for the construction and repair of kilns. This product is an inorganic binder with strong chemical bonding strength and high heat resistance (it can withstand temperatures up to 1800°C). Especially in the construction or repair of high-temperature furnaces, furnaces built with mortar prepared from refractory materials possess advantages such as seismic resistance, resistance to spalling, minimal shrinkage of the joints, tolerance to sudden temperature changes, resistance to high-temperature air currents, strong bonding between bricks, no brick detachment, and no leakage of heat. Since it contains no sodium ions, it prevents the formation of mullite powdery crystals when applying aluminum silicate refractory fibers; it is also easy to work with and maintain, allowing for energy savings of 30% to 50% ； Used for building or repairing furnaces, it can extend the lifespan of the furnaces by 1 to 3 times, reducing the costs associated with furnace repairs and the losses resulting from downtime. Technical properties: The strength data of the mortar prepared using this adhesive, as determined through testing, are as follows: 1. Tensile strength of the mortar (kg/cm2): 50 kg/cm2 after firing at 1100°C, and 70 kg/cm2 after firing at 1500°C. 2. Compressive strength of the mortar (kg/cm2): 261 kg/cm2 after firing at 1100°C, and 505 kg/cm2 after firing at 1500°C. 3. Adhesive strength between refractory bricks (kg/cm2): above 11 kg/cm2 at room temperature; 37 kg/cm2 after firing at 1100°C, and 54 kg/cm2 after firing at 1500°C.
When used as a material for concrete pouring, its strength data are as follows: 1. Compressive strength after firing: 285 kg/cm2 at 110°C, 407 kg/cm2 at 800°C, and 857 kg/cm2 at 1400°C. 2. Flexural strength after firing: 98 kg/cm2 at 110°C, 80 kg/cm2 at 800°C, and 200 kg/cm2 at 1400°C.
Using this high-temperature adhesive as a bonding material to mix with high-alumina materials to create concrete provides good workability at room temperature, while its strength and adhesive properties increase significantly at high temperatures. This results in excellent integrity of the poured concrete. Additionally, less amount of this high-temperature adhesive is required, making it cost-effective from an economic perspective. III. Application of aluminum silicate refractory fibers: In industries such as machinery and electrical equipment, a large number of resistance furnaces and heat treatment furnaces are used; to reduce heat loss, aluminum silicate refractory fibers are often employed for insulation purposes. Many factories use nickel-chromium wires for fixation, which not only results in high costs and difficulties when modifying the furnace, but also leads to poor quality in such modifications. Using a high-temperature adhesive can solve this problem well. By mixing a high-temperature adhesive with a certain proportion of refractory materials such as high-alumina powder or refractory clay, and then attaching aluminum silicate fibers to it, good adhesion is achieved through sintering and curing, resulting in a smooth surface. Suitable for various heat treatment furnaces, box-type or shaft-type resistance furnaces; it can be used continuously at high temperatures ranging from 1000°C to 1800°C without peeling, offers secure adhesion, and can save more than 50% on electricity consumption. It also has the following characteristics: ① It is inexpensive, costing about 1/8 of that of aluminum silicate refractory fibers fixed with nickel-chromium wires, thus allowing for significant savings in expensive metal materials. ②It is easy to construct, and the furnace lining is durable. ③It has good airtightness, excellent heat retention, and significant power savings. IV. Used as a heat-resistant flame-retardant coating to protect the substrate, reduce heat loss, and save energy. This high-temperature binder possesses excellent infrared absorption capabilities; when mixed with materials such as high-alumina powder to form a slurry, it can be applied to the furnace walls to create a refractory coating that effectively improves radiation resistance on the furnace walls and reduces heat loss. The coatings produced using it have a high fire resistance and strong corrosion resistance; when applied to the surface of objects, they serve to protect the materials. V. Used for material molding. On certain specific occasions, this adhesive is mixed with materials such as clay, mica powder, diatomite, and kaolin to bind them together and press them into the desired shape. VI. Used for bonding in other applications that require high-temperature resistance.

I have materials that are both insulating and heat-resistant; their specific gravity is 0.40, they can withstand temperatures of around 1600 degrees, and their particle size ranges from 300 to 45 microns. Contact number: 15093295550
I need the contact number of a precision mold manufacturer; it should be located within Henan Province. Thank you
It seems there is a substance called boron nitride that is resistant to high temperatures and insulating.

We have a type of fiberboard that can withstand temperatures of 1300 degrees, as well as bear pressure. I just don’t know how its insulation performance is. Because it hasn’t been tested. QQ 123610315, 13818330315 – we can communicate with each other.
