High Temperature Refractory Material​​​ belongs to acid refractory material, has good ability of resisting acid slag erosion, the softening temperature of load is as high as 1640 ~ 1670℃, the volume of long-term use is relatively stable under high temperature.


The High Temperature Refractory Material​​​ is mainly an acid refractory material composed of scale quartz, calcite and a small amount of residual quartz and glass phase.


The silica content of High Temperature Refractory Material​​​ is above 94%.True density 2.35g/cm3.It is resistant to acid slag. Higher high temperature strength. High refractoriness under load. In high temperature for a long time without deformation. Low thermal shock stability. Using natural silica as raw material, with appropriate amount of mineralization agent, to promote the conversion of quartz in the billet to scale quartz.


It is slowly fired at 1350 ~ 1430℃ in reducing atmosphere. When heated to 1450℃, about 1.5~2.2% of the total volume expansion, the residual expansion will make the cut joints close, to ensure that the masonry has good air tightness and structural strength.





1. Silicon oxide is above 95%.

2. Good acid erosion resistance.

3. High softening point with temperature.

4. No shrink in burn repeatedly.

5. Temperature of refractoriness under load is above 1650º C.

Stable Capability, High Quality, Excellent Service, Competitive price is the most important advantage of our products.




1). Gas cooker,Water heater,Gas oven, Gas boiler,Air-conditioning and so on.

2). As ceramic parts of flexible pad and channel heaters at operations of pre and postweld heat treatment; Welding process, stress-relieving, pre-heating & post heating, other resistance-heating environment
3). halogen lamps, high and low pressure uv lamps, mercury lamps, uv lamp holders and heating tubes.

4). high-power electrical applicance and all kinds of insulation device.
