Which material is silicon nitride with low conductivity and high heat resistance?

Explanation:
Silicon nitride combines two key properties: low electrical conductivity and high heat resistance, which is why it’s prized as a bearing material. This makes it a ceramic bearing material—the specific class of ceramics engineered for bearing use, where insulating behavior and high-temperature performance are crucial. Ceramics as a broader category can include materials that don’t meet this exact bearing-focused combination, while glass isn’t used for high-temperature, load-bearing bearings, and composites don’t guarantee the same insulating and thermal properties. So the description best matches Ceramic Bearing Material.
